I welcome everyone who stopped by. The review will focus, as you probably already guessed, on comparing three fairly well-known models of high-current batteries with a capacity of 3000mAh in various modes, including with a discharge current of 20A. This testing will allow you to tell how the battery behaves under different modes, and thanks to the capabilities of the iCharger 208B charger in the form of plotting graphs, you can compare head-to-head and find out which of them is better. If you are wondering whether they will pass the test and how they will behave, then you are welcome to the cat...
First, a few words about batteries:
A long time ago I wrote a short article about removing protection boards, where I briefly wrote about what Li-Ion batteries are and how they are marked, so in order not to inflate the review, I will not repeat myself. A little later, I decided to compare some models of high-current batteries, but since the necessary equipment was not at hand, the testing was more informative. About a year ago I purchased a proprietary charging and balancing device iCharger 208B, capable of discharging batteries with a current of 20A, so I decided to repeat the experiment. All copies have a declared capacity of 3000mah, with the exception of Sony VTC6, which has a capacity of 3120mah. I have long wanted to compare popular models of high-current batteries, but somehow I didn’t have the desire, since testing takes a lot of time. But by chance (thanks to the prize draw), I decided to assemble a normal stand and conduct a thorough comparison. Unfortunately, I ordered the batteries before the new year, so some models are already a year old, but I think the picture shouldn’t change much.
I have long adhered to the following classification of batteries based on maximum current output:
- low-current batteries - conventional banks with a maximum allowed current of up to 5A. These are the popular Samsung ICR18650-26FM/28A/30B/32A, Sanyo UR18650FM/ZY, Sanyo/Panasonic NCR18650B/BF/BL, LG ICR18650D1/E1/F1L, etc.
- medium current – intended for devices with a consumption of no more than 10A. These are mainly new products from 2015 with upgraded chemistry Sanyo/Panasonic NCR18650GA/BD/PF/PD, LG INR18650MJ1, Samsung INR18650-35E
- high-current – can withstand loads of 10A and above. These are cans for electronic cigarettes and power tools, which will be discussed in this review; see the list of models below.
Main models of high-current 18650 Li-Ion batteries:
- Sanyo UR18650W2 1500mah (20A max.)
- Sanyo UR18650RX 2000mah (20A max.)
- Sanyo UR18650NSX 2500mah (20A max.)
- Samsung INR18650-15L 1500mah (18A max.)
- Samsung INR18650-20R 2000mah (22A max.)
- Samsung INR18650-25R 2500mah (20A max.)
- Samsung INR18650-30Q 3000mah (15A max)
- LG INR18650HA1 1300mah (20A max.)
- LG INR18650HB6 1500mah (30A max.)
- LG INR18650HD2 2000mah (25A max.)

- SONY US18650VTC3 1600mah (30A max.)
- SONY US18650VTC4 2100mah (30A max.)
- SONY US18650VTC5 2600mah (30A max.)
- SONY US18650VTC5A 2600mah (35A max.)
- SONY US18650VTC6 3120mah (30A max.)
Packaging and appearance:
As mentioned above, the review includes three popular models of high-current batteries with a capacity of about 3000mAh (LG / Samsung / Sony): 
The batteries are supplied in a plastic box in a regular postal bubble: 
When purchasing a pack of 4 batteries from the GearBest store, you get a plastic box as a bonus: 
The exception is protected batteries, which simply do not fit in length. I would like to remind you that when you buy one or two batteries, they will be packaged in simple boxes, so it makes sense to buy packs of 4 or 8 pieces, especially since they are often cheaper. And a separate plastic box costs about $1.
Packaging and protection during transportation are, let's say, average. There have been cases where batteries arrived a little dented with the heat shrink stripped off, but in my experience this has not happened. The most that happened was a cracked box, as in this case (small crack on the lid): 
Official Specifications:
The length of all batteries is almost the same (65mm): 
The weight of batteries, in most cases, directly affects the capacity, i.e. the bigger, the better: 
Internal resistance measured by iCharger 208B charger: 
Internal resistance readings should not be taken into account, because correct determination is possible only with good equipment. Here, at a minimum, the resistance of wires and contacts is not taken into account, which may just be equal to a couple of tens of milliohms. But under equal conditions, chocolates show the worst results. Let me remind you that I made about 5 samples and took the average result.
Well, for company on the Opus BT-C3100 V2.2 memory: 
More detailed description of the models:
Next come the infamous LG HG2, popularly called “chocolate” for its specific color: 
The model is not bad, but there was a technological defect, which is why production was suspended. I don’t know what kind of marriage it was. Besides, this model has a huge number of fakes. These can be either high-current models with low capacity, or simply low/medium current batteries. How to distinguish a fake from an original by external features is written in an English-language blog. Here is a similar comparison, but on the Russian-language forum of steamers (simplified).
I have the original, which I had no doubt about, because... I have been buying batteries exclusively on GearBest for several years now: 
The production date for LG models is standard and is printed on heat shrink by laser engraving: 
The LG bank under review has the following designations - PO56B252AH(the first four characters are needed), i.e.:
- the first letter is the year of manufacture: J – 2010, K – 2011, L – 2012, M – 2013, N – 2014, O – 2015, P – 2016, Q – 2017, etc.
- the next three digits are the day of issue: 040 (40th day), it’s inconvenient to calculate...
Total: production date of LGDBHG21865 PO56B252AH – February 25, 2016.

Well, the last ones in line are the novelties of the past Sony of the Year VTC6 with a maximum capacity of 3120mah for this class of batteries and a current output of 30A: 
Several years ago, Sony officially announced the cessation of production of its line of high-current batteries (VTC4, VTC5), as a result of which the models beloved by many vapers began to be counterfeited, and the counterfeits were of a very high class. I wasn’t very interested in the topic of batteries back then, so I didn’t delve into it too much, but the fact is a fact. Since the batteries of this company really have high performance characteristics, it is not surprising that after some time counterfeits began to appear on VTC6. Judging by some information from thematic forums, fakes are also of good quality, but you can identify them by appearance It's still possible. Here are a couple of articles on how to identify fakes on VTC6, as well as on earlier models - and.
In my case, the original, because in most cases you can see Samson 30Q under the heat shrink, and it has a slightly narrowed positive contact. Sony has a positive contact strictly in the center and in diameter slightly smaller than the protective black ring: 
In addition, for original Sony cans the position of the QR code relative to the marking is not fixed and “walks” from instance to instance: 
Since fakes most often repack the cheaper Samson 30Q, it wouldn’t hurt to compare the recesses in the area of the positive contacts (mechanical battery protection, see the review on castration of Li-Ion cans): 
As you can see, the notches are different; a comparison with other models is in the specifications section (see above).
Production date Sony models standard and heat-shrinkable using laser engraving: 
We are interested in the last 5 characters on the bottom line - C6A13 YF22T:
- the first letter is the year of manufacture: W-2014, X-2015, Y-2016, Z-2017
- second letter – month of release: A – January, B – February, C – March, D – April, E – May, F – June, G – July, H – August, I – September, J – October, K – November , L – December
- third and fourth digits – day of issue (1-31)
- the last (fifth) letter is not of particular interest
Total: production date of Sony US18650VTC6 C6A13YF22T – June 22, 2016.
For those interested, the full transcript of the bottom line suggests:
- the first letter is the name of the manufacturer (K – Sony Energy Devices Koriyama Plant in Japan)
- the next two characters after the space are the model name (C6 – battery model VTC6)
- the next three characters are the internal production code
- the next four characters are the date of production of the can (see above)
- the last letter is something related to electrodes (Electrode History)

Testing:
I tried to provide the most equal testing conditions for all batteries, but unfortunately, the chocolate skis were a little stale and possibly from a defective batch, or maybe just with a corrected defect from new batches. At the beginning of February there was a review of chocolates, the production date was already P249 (September 2016). Therefore, I ask you to be skeptical about the results obtained. I don't like them and I'm not going to order them again, sorry.
In order to minimize discrepancies in the results (losses on contacts, heating), I did not disassemble the stand until I tested all three batteries in a specific mode. Before each subsequent test there was a pause of about 10 minutes in order to Charger and the load cooled down. To minimize losses, a modified battery holder (holder) was used. For tests at currents of 1A and 7A, the batteries were charged in the Opus BT-C3100 V2.2 charger and, before the test itself, “achieved” in the iCharger 208B charger. Since these modes are not of particular interest and are somewhat long in time, only one bank was tested, with the exception of Skis. I didn’t like the result and I ran the second battery at 1A. The result was similar. But for the 20A test, I charged the batteries with a branded Xtar SP1 charger and did two tests. The result was the best. In the 20A test, active cooling was used in the form of a household floor minifan and an external load, because the heating of all components was quite high. Don’t also forget that Sony VTC6 releases its entire capacity when discharging up to 2V!
So, first, the results of measuring the capacity in the Opus BT-C3100 V2.2 memory, which I did a long time ago:
The results are just for informational purposes only. it slightly overestimates the readings and cannot discharge below 2.8V. In addition, such a run is necessary for the batteries to reach their nominal capacity. It is recommended to perform a couple of charge/discharge cycles.
Test for discharge current 1A in the iCharger 208B charger: 
The graphs are almost closely matched; Sony, although slightly, is still in the lead both in capacity and in the ability to maintain voltage under load. Samsons are a little ahead of Skis and show greater capacity, although in theory it should be the other way around - Skis should lead by a small margin at low currents, and Samsons at high currents. I specifically tested two different LG batteries, but the result was the same. In my opinion, the Skis showed the worst results either because of their age (the difference with the ones being reviewed is six months), or they actually have a defect, or just with a corrected defect. Often, after technological defects are eliminated, the performance characteristics of the model decrease. As a trivial example, problems with electrode insulation (separator). A few months after sales, it turns out that, suppose, under heavy loads on the can, the insulation may be damaged as a result of heating. The company conducts additional tests and if this is confirmed, it returns all shipped shipments. To eliminate the defect, technologists suggest increasing the thickness of the separator, and since The internal volume of the can is limited, which means that the working area of the electrodes has decreased, and with it the capacity. Let me remind you once again that this is just a banal example and does not apply in any way to Lg banks. Or maybe I just came across jars with quality class “B” or “C”.
In any case, when all three batteries are discharged with a current of 0.6A (according to the datasheets), they should return their nominal capacity.
For those interested, original graphs from the LogView 2.0 program (Samsung -> Lg -> Sony):
Next, a discharge test with a current of 7A in the iCharger 208B charger without external load and cooling:
It becomes noticeable how the voltage drops under load, after all, it’s already 7A. Here Sony is again the clear leader, although the gap is again small (0.05V). The skis are again drained both by capacity and by subsidence. In my opinion, this is the most common operating mode ( e-Sigs, power tool), so it’s better to focus on it. The heating of the cans is small.
For those interested, original graphs from the LogView 2.0 program (Samsung -> Lg -> Sony):
Well, the most interesting mode discharge current 20A in the iCharger 208B charger with external load and forced cooling:
The graphs show that there is practically no difference between the 30Q and VTC6 in terms of ability to withstand high loads. The only difference is the slightly higher capacity/energy output. But HG2 failed here in every sense. Therefore, we can conclude that there is practically no significant difference at high (maximum) currents between 30Q and VTC6. Don’t also forget that Sonya releases its entire capacity when discharging up to 2V. I’m not a steamer, but in my opinion, only a few mods can provide such a load (I could be wrong), so there’s no point in overpaying for Sonya.
Let me explain a little about the stand. Due to the operating characteristics of the iCharger 208B charger, the current increases gradually in discharge mode. In our case, the rise to the maximum value was 65 seconds (I don’t know how to get around this). When the batteries were discharged during intensive cooling, the temperature at the end of the test was 66-68°C for Sonek and Samson, and for Ski it was as much as 72°C. It is not difficult to guess that heating in such cases acts as a catalyst and batteries show better results.
That's all for those who are interested, original graphics from the LogView 2.0 program (Samsung -> Lg -> Sony)
I agree that there is no point in scolding chocolates, since the conditions are not entirely equal, so I suggest that you familiarize yourself with the results of foreign testers.
Comparison in well-known comparators:
Now let’s compare our charges in the popular Danish comparator at the same currents 7A/20A (Samsung on the red graph, Lg on the blue): 
Hmm, doesn't remind me of anything? The behavior of both models resembles the situation in my testing, the discharge graphs are similar, but here the Dane did not use external cooling and the test was stopped prematurely (vertical rise of the graph - “recovery” of the battery).
The picture is the same when comparing Samsons with Sonya (Samsung on the red graph, Sony on the blue): 
The gap is quite small.
I have already mentioned several times above that the new Sony VTC6 is not particularly worth idolizing; they are only slightly ahead of the Samsung 30Q. Many attribute to Sonya a slightly longer operating cycle at high load currents and a slightly larger delivered capacity/energy. I agree with the latter, but about the resource it’s not entirely true. First, let's look at the Samsung 30Q datasheet, which clearly states that when comparing 15A vs 22A cans, the service life is reduced by 50 cycles: 
I'll try to explain more clearly. One cycle is equal to the full charge and discharge of the bank and usually for high-current banks is equal to 250-300 cycles, after which a significant drop in capacity is observed. There is an opinion that the number of cycles is an indicator at which the manufacturer guarantees 70-80% residual capacity, i.e. after the extreme maximum cycle, the battery capacity will be at least 70-80% of the nominal. I cannot say which statement is true, but I lean more toward the first. In the graphs above, the number of cycles is indicated horizontally (Cycle number), judging by which it can be seen that with a discharge current of 15A, after 300 charge/discharge cycles, the capacity of the jar decreased to 2200mah. But with a discharge current of 22A, after 250 cycles the capacity of the jar was 2200mah. Those. when the discharge current increases by 7A, we “lose” 50 cycles.
In the Sony VTC6 datasheets you can see the following test, from which it follows that when discharged with a current of 10A after 300 charge/discharge cycles, the capacity of the can is 2000mah: 
Comparing with the Samsons, which at 15A and 300 cycles showed a capacity of 2200mah, the Sony result (2000mah) at less than 10A is somewhat depressing.
Well, the skis are worth mentioning: 
But here it gets a little more interesting. When discharged with a current of 15A after 600 cycles, the residual capacity of the jar was about 2250mah, but with the maximum allowed 20A, the result is already similar to the Samsons (250 cycles and 2200mah). But here the discharge is up to 2V! It turns out that with the worst load parameters of the whole three, Skis have the longest lifespan, but only at currents up to 15A, :-)
Unfortunately, this is only information from datasheets, but still. And finally, a small photo of Samson’s impact/crushing tests: 
Not every jar can withstand such abuse :-)
Typical applications for high current batteries:
- e-Sigs
- power tools – screwdrivers, drills, hammer drills
- assembly of batteries for electric vehicles
- powerful "custom" lights, especially with a boost driver
To summarize, I would say that the Samsons are a proven workhorse, the Skis are the company's attempt to give a quick answer to Samsung with their 30Q, but as usual, the rush did not lead to anything good. Sony was the latest to release its VTC6 and gave them some publicity, but the gap is not significant, as it is attributed, and in terms of resource it is completely behind everyone else. My choice is definitely Samsung 30Q, but decide for yourself which one to choose...
Most manufacturers try to make flagships thin. This is understandable, since low weight and thickness of the body are important criteria for a TOP-class smartphone. If we neglect this, then new flagship will look like a mid-range smartphone and it will fail to sell. Naturally, it is impossible to build into a thin body capacious battery, since current technologies do not allow the creation of such a battery. So it turns out that cool phones with huge power-hungry screens and powerful processors are equipped with 3000-3500 mAh batteries, but there are exceptions.
This review uses the results of studio autonomy testingGSMArena, links to sources at the end of the article.
1st place – Huawei Mate 20X
The most enduring smartphone was created by Huawei. We are talking about the Mate 20X model with a huge 7.2-inch screen. Due to its huge size, this “shovel” received a capacious 5000 mAh battery, which, paired with a low-power processor, OLED matrix and optimized shell, provides solid autonomy.
A full battery charge is enough for:
- 28:49 hours of communication
- 15:32 hours surfing the Internet with backlight 200 cd/m2
- 17:56 h video playback
Such results allow us to put the flagship in first place - no other TOP-class smartphone is capable of this. Plus, the device supports fast charging SuperCharge, and comes with a compatible 5V/4.5A adapter, which gives a power of 22.5 W. With him huge battery 5000 mAh charges up to 47% in 30 minutes; up to %100 – in 100 minutes. Unfortunately, there is no wireless and reverse charging, as on Huawei Mate 20 Pro.
Autonomy is not the only strong point apparatus. It is made on the latest 7-nm HiSilicon Kirin 980 processor, equipped with the same camera unit as the Huawei Mate 20 Pro (ranked 2nd in the ranking of camera phones), which means that it takes photographs no worse. Plus, there is a cool OLED matrix with support for HDR10 and infinite contrast, NFC and a set of up-to-date interfaces that any TOP smartphone of 2019 should be equipped with.
You can praise the device for a long time, but it is more important to highlight the shortcomings. Firstly, there is no protection against water, only splash protection is claimed, and this is not serious. Secondly, there is no wireless charger and LED event indicator. Thirdly, the device only supports branded nano memory cards - they are very expensive. On the official Huawei website, such a 128 GB card will cost 5,000 rubles.

2nd place – Huawei P30 Pro
A completely new flagship, which is not yet sold in Russia, but has already been officially presented and went on sale in other countries. One of these days it will hit the shelves of Russian stores.
Studios have already tested the smartphone, and DxOMark experts recognized it as the best camera phone in the world. The cameras here are truly revolutionary - you can read about this in full, but for now we are interested in the battery and autonomy.
P30 Pro is equipped with a 4200 mAh battery, which is enough for:
- 27:40 hours of communication.
- 14:21 hours surfing the Internet at 200 cd/m2.
- 20:16 hours of video playback at 200 cd/m2.
Fast, wireless and even reverse charging are supported. With the “native” adapter that comes with the kit, the phone charges up to 70% in 30 minutes; up to 90% in 45 minutes; a full cycle lasts 60 minutes, and this is a record among phones with 4000+ mAh batteries. Obviously, the Chinese have done a good job optimizing energy consumption, and the result is one of the most standalone flagships in the world.
On the market, Huawei P30 Pro is not positioned as very standalone smartphone, the emphasis is on his cameras - there are three of them. The main sensor has a resolution of 40 megapixels and a Quad-Bayer filter, which allows you to combine adjacent pixels on the matrix into one large one. This really improves the quality of the photo, expands the DD and reduces the amount of noise. The second and third modules have wide-angle and telephoto lenses. P30 Pro is the first device with 10x hybrid zoom and 50x digital zoom.
NFC, an under-screen fingerprint scanner and other flagship stuff are included. All this makes the Huawei P30 Pro one of the coolest in the world, not only in terms of cameras or autonomy, but in general.
Flaws:
- Lack of 3.5 mm headphone jack.
- There is no 4K/60 FPS shooting function.
- No stereo speakers.
- Front camera with fixed focus.
- Branded Huawei NM memory cards are expensive and rare.
Offers on the market:
- Official Huawei store – 69,990 rubles + 2 cool gifts

Benchmark results (performance testing):
3rd place – Samsung Galaxy Note 9
I’ll say right away – the phone is controversial. As a result of testing in the GSMArena studio, the device showed high battery life results, but buyers in reviews complain about the rapid drainage of the battery.
Since the review was compiled according to GSMArena data, it falls into third place in the ranking. Fully charged Galaxy Note 9 withstands:
- 28:13 hours of communication.
- 12:36 hours of surfing the Internet at 200 cd/m2.
- 16:45 hours of video playback at 200 cd/m2.
In talk mode, the device lasts even longer than Huawei Mate 20 Pro. The kit comes with a 15W charger - something Samsung has offered since the Galaxy S5. With it, the smartphone charges up to 37% in 30 minutes, which is very good considering the 4000 mAh capacity. A full cycle will take 1:46 hours.
These are the testing data. But, judging by the reviews of owners on w3bsit3-dns.com, many are faced with excessively high energy consumption. Possible reason– in the hardware of phones. Various models are equipped with different controllers, modems and other components, which in theory can affect autonomy as a whole. Therefore, the figures above may be erroneous.
The smartphone itself Samsung Galaxy The Note 9 is simply stunning, with a quality build, water resistance, a powerful 10nm processor and a near-flawless front camera. It took 3rd place in the DxOMark rating, losing the first 2 positions to the more recent Galaxy S10+ and Google Pixel 3.
Flaws:
- Very high price on the market.
- Heavy weight - more than 200 grams.
- Design is not for everybody.

4th place – Honor View 20
Another phone from Huawei, equipped with a capacious battery and cool, optimized software. This is the world's first smartphone with a hole for the front camera, which made it possible to achieve almost maximum framelessness.
The phone is equipped with a 4000 mAh battery that can withstand:
- 30:00 h of communication.
- 15:26 hours of surfing the Internet at 200 cd/m2.
- 15:48 hours of video playback at 200 cd/m2.
In the kit you will receive a 22.5 W adapter with support for Huawei SuperCharge technology - in 30 minutes it charges the phone up to 59% from zero and up to 94% in 1 hour. In addition to autonomy and charging speed, the smartphone is valuable for its cool screen with a brightness of 479 cd/m2 and a contrast ratio of 1313:1, and most importantly, accurate color reproduction. Here, the color error is only 1.5 as a result of manual calibration, which makes the Honor View 20 matrix one of the best.
The camera in Honor View 20 is Sony IMX 586 with a resolution of 48 megapixels and an f/1.8 aperture. It uses a Quad-Bayer filter, like the Huawei P30 Pro. With it you get pictures in 12 megapixel resolution, but of higher quality. Additional camera– 3D ToF sensor, it offers body contouring function and provides portrait mode.
Honor View 20 is much cheaper than the previous smartphones in the TOP, while it is slightly inferior to them in terms of autonomy and photography quality, but overall it is worthy of the highest ratings.
Flaws:
- Not the best IPS screen on the market.
- There is no slot for a memory card.
- The 3D-ToF camera is practically useless. Essentially, it replaces a banal depth sensor.

5th place – Xiaomi Mi 9
But the main thing in this review is the 3300 mAh battery, which produces:
- 23:32 hours of communication.
- 12:15 hours surfing the Internet at 200 cd/m2.
- 16:57 hours of video playback at 200 cd/m2.
The phone supports fast and wireless fast charging and comes with an 18W wired adapter that delivers 45% power in 30 minutes. Xiaomi offers for $20 to buy a set of two adapters - a wired one with a power of 27 W and a wireless one with a power of 20 W. As a result, the charging speed will increase to 70% in 30 minutes, and this is already a serious claim to leadership.
Xiaomi Mi 9 is a real flagship based on the Snapdragon 855 chip, with a cool OLED screen with HDR10 support and protective Gorilla glass Glass 6, advanced cameras - in the DxOMark camera phone rating it comes right behind the Samsung Galaxy S10 Plus and is ahead of the iPhone XS Max, HTC U12+, Samsung Note 9.
Flaws:
- No protection from water.
- There are no stereo speakers or 3.5mm headphone output.
- There is no slot for a memory card.
- No optical stabilization. Despite this, he was included in the ranking of the best.

What smartphone models are there with a battery of 3000 mAh or more?
Continuing the series of articles about smartphones with powerful batteries, today we will look at models with a battery of 3000 mAh or more. There are quite a lot of such devices on the market today. In general, most smartphones from the average price category have batteries with capacities from 1800 to 2500 mAh. So, models with a battery of 3000 mAh or more are slightly higher in this rating. But these are not necessarily top-end smartphones from well-known companies, but rather the opposite. Famous manufacturers are just beginning to turn towards increasing time battery life your gadgets. This is a new user requirement and cannot be ignored.
In the meantime, most smartphones with capacious batteries are produced by little-known companies. There are quite a lot of proposals. Quite a few models with a powerful battery are found among. Basically, all phones that are equipped with a 3000 mAh battery or more have decent hardware specifications. But they cannot be called top and record-breaking. In principle, this is not necessary.
Most users are satisfied with the performance of an average smartphone. The main thing is that it works longer in offline mode and fully lives up to its name - a mobile phone.
So, let's consider smartphones with batteries from 3000 mAh.
This is a fairly expensive (40-45 thousand rubles) smartphone with powerful hardware and a high-quality display. The battery capacity is 3000 mAh. The device has the ability to work with two SIMs and a display with a diagonal of 5 inches. The resolution is 2560 by 1440 pixels.
LG G4 H818 has a front camera with an 8 megapixel sensor, and a main one with a 16 megapixel sensor. The latter is equipped with an LED flash. The asset of the smartphone is a CPU with 6 cores, operating at a clock frequency of 1800 MHz. It works with 3 gigabytes of RAM. Internal memory is 32 GB. It can be expanded using memory cards.
A 3000 mAh battery is enough for at least a day of active use. If you use the LG G4 H818 moderately, the battery will last two days. Considering the large display and powerful hardware, this is a good result. Some users in reviews complain about the inconvenient phone interface.
When installing a 6000 mAh battery, the Highscreen Boost 2 SE becomes quite bulky. This is the price to pay for the long battery life. With this battery, the smartphone can show video for 21 hours or withstand 14 hours of surfing the Internet via 3G.

The article will tell you how you can buy a smartphone with a good battery.
Battery capacity is the most important characteristic of a smartphone. Therefore, if a smartphone has a good battery, then it will most likely be a good smartphone.
Why is battery power the most main characteristic smartphone?
From a technical point of view (in terms of its “stuffing”), a smartphone is identical to a tablet. Which means the same level of energy consumption as a tablet. Moreover, the level of energy consumption of a smartphone can be even higher than that of a tablet, due to the fact that the smartphone must be constantly connected to the cellular network. Namely, the work of adapters wireless communication(cellular, WiFi, Bluetooth) in second place, after the screen, in terms of energy consumption. Moreover, it is also important that today people very often use a smartphone to view social media or websites. And this also increases the battery consumption of the smartphone - the display works for a long time, the WiFi adapter is working or the cellular adapter is working in data transfer mode.
And such requirements for long-term autonomy are what make you buy a smartphone with a powerful battery.
With all this, the physical dimensions and weight of a smartphone are approximately two (or even more) times smaller than that of a tablet (meaning tablets with a diagonal of 7-8 inches).
And the size of the device imposes a limit on battery capacity. For the simple reason that the capacity of modern batteries depends on their physical size and weight.
That is, the smaller the smartphone, the weaker the battery.
Therefore, for cheap, and for many budget, and even expensive smartphones, one day of work without recharging may be unattainable. At first glance, there is nothing wrong with this, because you can charge the battery.
The problem is that batteries have a limited number of charge-discharge cycles. Cheap batteries usually last about 300 cycles, good (expensive) ones can last up to 500 cycles.
And if you have a cheap Chinese smartphone that needs to be charged every day, then in less than a year its battery will “die” and you will have to change it. And these are additional costs. And time to find a suitable battery. Or maybe such a battery won’t be able to be found at all. And then you will have to buy a new smartphone.
But the problem of quickly dying batteries can also occur on an expensive smartphone. Even if on a smartphone good battery, which can withstand 500 charge cycles, but its capacity is small and you have to charge it every day, it will last less than two years.
So battery capacity is the most important characteristic for a smartphone.
Models with a capacity of less than 1500 mAh (milliamps per hour) can be excluded from the list of candidates altogether.
At the same time, it is important to understand one feature - for cheap and budget Chinese smartphones, the declared battery capacity usually does not correspond to the real one. The specifications of such a smartphone may indicate a battery capacity of, for example, 1500 mAh, but in reality its capacity will be noticeably less, it’s good if it’s at the level of 1200 – 1300 mAh. And if it is written that the battery capacity is 2000 mAh, in reality it could be, for example, 1500 mAh.
There is even such an ironic expression - “Chinese watts”. It appeared a long time ago, in relation to cheap Chinese power supplies. But this expression fully applies to cheap Chinese batteries.
Battery capacity in cheap Chinese smartphones, you can safely reduce the percentage by 20-25.
There is another unpleasant feature of cheap Chinese batteries. They die quickly. They have a shorter charging cycle life. They have a higher number of defects. As a result, when buying a cheap Chinese smartphone, there is a high probability that in a little over a year, or even earlier, you will end up with a dead battery.
Smartphone with good battery
Batteries are considered the most durable Samsung smartphones. Sony and Nokia are not far behind them (now these are Microsoft smartphones). In addition to durability, smartphones from these manufacturers have honest battery capacity. If Samsung or Sony indicate in the specifications of a model a battery capacity of 1700 mAh, then you can be sure that it will be that way. There is a very high probability that an honest and reliable battery will be found in smartphones from manufacturers such as HTC, Asus, Acer, Lenovo.
Chinese smartphones costing more than $200 can also have good batteries.
Smartphone with a powerful battery
There are no standards here, but I think that a battery with a capacity of 3000 mAh or higher can be called large.
However, you need to understand that such a smartphone will either be large in width and length (screen diagonal 5.5 or 6 inches). Or, with a screen size of 4-5 inches, it will be a thick smartphone - 10 mm thick or more. And the weight, accordingly, will also be at least 140 - 150 grams.
There are no miracles. There are no small and capacious batteries yet. So when choosing a smartphone with large battery you automatically choose a smartphone that is large in size and weight. This size can be distributed in different ways. Or thin (7-8 mm), but with a large width and length. Or small width, but thicker (9-12 mm).
And don’t forget about the cost of the smartphone and the manufacturer.
If the Chinese company “Uncle Liao” offers a smartphone for $100 with a 4000 mAh battery, then with a 99% probability it will not be 4000 mAh at all. Or it will be an “overclocked” battery, in which the capacity is increased by raising the voltage to 4.35 volts and such a battery will not last long. Read the article Why Lithium Batteries Destroy, it describes how the Chinese are increasing the capacity of batteries.
Removable or non-removable battery
In the last couple of years, many models with a non-separable body have begun to be produced. That is, of course, he understands it, but with the help of tools. Accordingly, the battery in such a smartphone cannot be easily replaced on your own. And this may mean an increase in the cost of owning such a smartphone. If you have to replace the battery, you will have to contact specialists and pay money for it.
Reduced battery consumption
Regardless of the platform (Android, Windows or iPhone), the main battery hogs are:
- Display.
- Wireless adapters - WiFi, cellular in data transfer mode (3G, 4G) and Bluetooth.
Thus, reducing battery consumption means reducing the use of these cells. If you don’t watch videos on your smartphone and use the Internet as little as possible, then the battery life on one charge can even be several days (depending on the battery capacity and system settings).
A few tips that will allow you to reduce battery consumption:
- Always keep WiFi, Bluetooth and Data turned off. Turn them on only when you need them and turn them off immediately after use.
- Reduce display brightness.
- Always remove unused applications from RAM. The list of applications loaded into memory opens differently in different operating systems. B It could be separate button or long tap on the “Back” button.
- Turn on airplane mode at night. Better yet, turn off your smartphone completely.
- Look at the settings of your smartphone, if there is a battery saving mode, turn it on.
How to extend battery life
It was already written above in this article that smartphone batteries (as well as tablets and laptops) have a limited number of discharge-charge cycles.
What’s interesting is that the number of these cycles depends on the depth of battery discharge. The more discharged the battery is (before charging), the fewer charge cycles it can withstand.
If you discharge the battery completely (before turning off the smartphone), then the number of charge cycles is the lowest - good batteries have approximately 500 cycles. But if you put it on charge before the battery is completely discharged, then the number of charge cycles increases. If you start charging with 50% remaining charge, then the number of cycles increases to more than 1000. If you charge the battery with 80% remaining (20% discharge), then the number of cycles increases even more. However, such frequent charging (at 80% or 90% battery) can be inconvenient. And the total battery life in this case does not increase. The optimal option is to charge at 40-50 percent of the battery remaining.
A few rules that will extend the life of your battery.
- Do not charge the battery to 100%. More precisely, you need to monitor the battery voltage and not allow it to exceed 4.2 volts, which usually means less than 100% charge.
- Do not leave a fully charged phone connected to the charger. A common mistake is to charge your phone overnight. The battery is charged in 2-3 hours, and then, already charged, remains charged for another 5 hours. The batteries have controllers that monitor the discharge and charge and automatically turn off the battery or charging. However, such a controller may fail during operation. So it's better to be safe.
- Use only the standard charger. Better yet, charge the device from USB port computer.
- Do not keep your smartphone near heat sources; lithium-ion batteries do not like heat.
Read a separate article that details the factors that destroy a lithium battery. And in the same article there are detailed tips for extending the life of a lithium-ion battery.

Consider the LiPo labeling batteries using the example of a battery that has the following inscriptions:
- 3000 - capacity in mAh (mAh);
- 11.1 V- rated voltage;
- 3S- the number and order of connection of cans (individual batteries from which the battery is assembled) - this means that the battery is connected in series from 3 batteries, that is, the battery capacity will be 3000 mAh, and the voltage will be 3.7x3 = 11.1V;
- 20C- discharge current (on a battery 3000 mAh means that the maximum continuous discharge current is 20*3000=60000 mA=60A).
Voltage
On batteries, instead of voltage, the number of cells is written.
The voltage of one bank is 3.7 V. Accordingly, 3 banks are equal to 11.1 V.
The number of cans is indicated by the letter S.
Discharge current
Denoted by the letter C and a number of capacitance coefficients.
For example, if the battery says 20C, and its capacity is 3000 mAh (3 Ah),then the output current is 3 Ah * 20 C = 60 A
Peak discharge current
The current that the battery can supply for a short period of time (which is also indicated in the characteristics). Usually it is 10-30 s.
It is designated in the same way as the discharge current, by the second number.
20C-30C means that the discharge current is 20C, and the peak current is 30C.Capacity
Denoted in mAh (milliamp-hour). 1000 mAh = 1 A/h.
Charging batteries.
LiPo batteries are charged with a current of 1C (unless otherwise indicated on the battery itself, in Lately appeared with the ability to charge with a current of 2 and 5C). The standard battery charging current is 1000 mAh - Ampere. For a 2200 battery it will be 2.2 amperes, etc.
The computerized charger balances the battery (equalizing the voltage across each battery bank) during charging. Although it is possible to charge 2S batteries without connecting a balancing cable, we strongly recommend always connect the balancing connector! 3S and large assemblies should only be charged with the balancing cable connected! If you don’t connect and one of the cans reaches more than 4.4 volts, then you will be in for an unforgettable fireworks display!
The battery charges to 4.2 volts per cell (usually a few millivolts less).
Storage mode.
On a computerized charger, you can put the LiPo into storage mode, and the battery will be recharged/discharged to 3.85V per cell. Fully charged batteries will die if stored for more than 2 months (maybe less). They say that they are also completely discharged, but for a longer period.
Exploitation.
It is not recommended to discharge a LiPo battery below 3 volts per cell - it may die. Engine regulators have the function of shutting down the engine when this condition occurs. We use z or . We also recommend using. It is connected to the balancer connector and when it beeps, it’s time to land.
When the motor consumes more current than the battery can supply, the LiPo tends to swell and die. So you need to strictly monitor this!
Now there are nano-tech batteries with a current output of 25-50C.
Preparing for work.
Getting the LiPo ready for use is very easy - just charge it and that's it! :)
This type of battery does not have a memory effect (no need to discharge before recharging), no cycling required - charge-discharge cycles before use.
If you charge in the field, then you should look for batteries with accelerated charging; they are labeled Fast charge 2C or 5C. In theory, they can be charged with a current of 33 Amps!
The charger has a maximum of 5A, but this will also reduce charging from 50 minutes to 20! (battery 1000 mAh)
