Sometimes it can be so difficult to put your smartphone or tablet aside and distract yourself from texting social network that you have to use the device while charging. Can I use my smart phone while charging? This question is asked by visitors to our site in the comments, so we decided to write this note for those who doubt it.
Over time, the capabilities of smart bodies are expanding, and energy consumption is growing along with the advent of new functionality. At the same time, the battery capacity increases; it takes longer to charge them or I use chargers with higher currents. Therefore, using a smartphone or tablet while charging may not be straightforward. Let's look at what this entails and whether some media outlets are deliberately aggravating the situation in order to attract attention to themselves?
What is the danger
The more electronics that fit into the small plastic or metal body of a modern smartphone, the greater the capacity of the battery that powers the phone. This is not always what happens, but there is a tendency for it to happen. The more energy stored, the more likely the smartphone will heat up when active work electronic components. This is the main danger of using a smartphone while charging the battery. The device may simply overheat, at best it will turn off, at worst it will explode.
Everyone knows the cases of sensational battery explosions on Samsung devices. In 80% of cases this happened during charging from a power source, and only 20% from other reasons, such as bending the case and, as a result, damage to the battery. For Li-ion batteries mechanical damage can be fatal, causing “self-destruction” of the latter, as a result of the uncontrolled release of energy located inside.
Use high-quality memory
Make it a rule to use high-quality, or even better, original charging device, only they are able to provide the correct and safe charging current for phones or tablets. A Chinese low-quality power supply may not cause an explosion and destruction of your device, but it can burn microcircuits and the power controller without any problems.
Manufacturers have made it a rule to prevent possible incidents of this nature by limiting at the hardware level the current supplied to the tablet or battery. cell phone. But heating of the case and the entire device can be caused not only by problems with the energy storage device.
You've probably noticed that when you actively use the device, for example for games, it heats up noticeably, turning into a small stove. This is due to the heavy load on CPU, performing millions of calculations per second. If you charge the gadget at this time, the device will significantly overheat, and you know how this can end.
Therefore, the answer to the question whether it is possible to use a tablet or smartphone while it is charging is YES, but following some rules.
- Avoid running too many apps when using your device while the battery is charging
- It is highly advisable not to play 3D games, as they put a huge load on the processor, which in turn begins to consume a lot of energy, taking away from the battery. The battery begins to heat up along with the microcircuits.
- Active use mobile internet while filling the battery with energy, it also provokes strong heating in the area of the signal transmitter, which can also lead to problems.
Using a power bank
Replenishing battery energy from power bank not the same as from the outlet. The voltage in such things is significantly lower than that of a standard power adapter, so in this case, the risks of explosion or damage to the battery are minimized. In this case, you can use the tablet while charging without any special consequences for it, but it is worth considering that filling with energy will occur very slowly and slowly, if at all. It is possible that the power consumption of the processor and graphics subsystem will exceed the capacity of the power bank.
It doesn't hurt to be careful
You can use a smartphone while recharging the battery, but with restrictions; we talked about them in more detail a little higher in this article. Now we’ll tell you what should alert you when strange reactions from the tablet appear.
- The battery is swollen - run to the experts, it needs to be replaced urgently, otherwise larger problems will begin.
- The case is so hot that it is difficult for your hand to endure - most likely an important microcircuit responsible for controlling energy consumption has failed, this is also the path to repairmen.
- You can use your phone or tablet while charging, but the battery will take a very long time to charge, especially if you play a 3D game with good graphics.
- Do not leave the power supply plugged in for long periods of time, such as overnight.
Is it wise to leave the charger in the outlet? If you don't know the answer, then I'll explain. This is not only fraught with increased electricity bills, but also threatens the apartment owner with a fire. No matter how high-quality the charger power adapter is, there is always the possibility of a short circuit due to a voltage drop in the network. The unit may simply stop working, in the best case, and in the worst case, it will also take things adjacent to it with it, causing a strong fire.
Is it possible to leave the phone on charge for a long time, say overnight? I think you understand everything, and you yourself will give the correct answer to the question posed.
Conclusion

How often should you charge your smartphone, and does constantly charging it to 100 percent reduce battery life? We have collected the most useful tips and recommendations for proper charging.
The battery is the most uninteresting and trivial topic for smartphone owners... but not when the charge level on the device approaches zero.
Why save your smartphone battery?
Many of us worry about extending our phone's battery life when we don't have a power outlet nearby, but few of us think about extending the life of our battery in general (which can sometimes go up to three to five years). Although there are some methods, using which you can keep the battery in good condition for a very long time and provide it with a long life.
Batteries don't last forever. Many smartphone manufacturers estimate the lifespan of their batteries at 300-500 discharge-charge cycles.
So, Apple company claims that after 1,000 such cycles, the battery capacity of their laptops is reduced by 20 percent.
After many recharges, the battery will no longer be able to store the same amount of electricity as it could before, and will only power the gadget for a short period of time.
That's why we decided to put together tips on how you can increase battery life at the most different devices: iPhones, smartphones Android platform or Windows Phone, as well as tablets and laptops.
Perhaps the most pressing question on this topic. Do I need to wait until the battery is completely discharged before charging it to a hundred percent? People ask a similar question because somewhere they once heard about a not very clear term, the so-called battery memory effect.
What is this battery memory effect, and what is it used with?
The battery memory effect is due to the fact that batteries seem to “remember” the remaining charge level if the capacity was not fully used in previous operating cycles, and if this happens frequently. Thus, a battery that is regularly recharged from 20% to 80% can “forget” about 40% of the uncharged capacity (from 0 to 20% and from 80 to 100%).
It sounds ridiculous, but there is some truth to this, which, however, only applies to old nickel (nickel-metal hydride and nickel-cadmium) batteries, but not lithium-ion batteries.
Lithium-ion batteries are not subject to the memory effect, so you need to deal with them differently: charge them often, but not completely, and do not let them discharge completely.
It's better to not charge your phone completely
The principle of handling a lithium-ion battery is to generally charge it either halfway (50%) or a little more. If the charge level drops below 50%, you should recharge the battery a little if possible. Several recharges a day in this mode will be more than enough.
But you shouldn't charge the battery to 100%. Of course, if you do this, nothing bad will happen to him. However, regular charging to 100% reduces battery life.
So, on a lithium-ion battery, it is best to keep the charge level between 40% and 80%. And make sure that it does not fall below 20%.
How often should the battery be fully charged?
It is recommended to fully charge the battery no more than once a month. When fully charged, the battery is recalibrated; it can be compared to rebooting a computer or, in a more everyday sense, a vacation that a person takes. By the way, the same applies to batteries in a laptop.
Should you leave your smartphone charging overnight?
Many modern smartphones can stop charging on their own when the battery capacity is full, so the user does not take much risk by leaving his gadget to charge overnight. However, some experts recommend removing the phone from the case when charging for a long time, as overheating may occur. Lithium-ion batteries don't do this too well (more on that below).
Should I use the function? fast charging?
Many Android smartphones have a fast charging feature, often referred to as Qualcomm Quick Charge technology or, in the case of Samsung, Adaptive Fast Charging.
These devices have special code baked into the processor called a power management integrated circuit (PMIC). It communicates with the charger and sends it a request to supply a higher voltage.
What about the iPhone?
The iPhone 6 does not have such a function, however, thanks to the built-in Qualcomm processor power management scheme, the device detects when it is charging using a high-amp charger (like the one that comes with the iPad). And it’s even good that there is no fast charging technology here, because in this case lithium ion battery heats up and, accordingly, wears out faster.
High, like very low temperature, negatively affects battery life. So being in the refrigerator or snow is also extremely undesirable.
It is better to disable the fast charging function on your Android smartphone.
Is it possible to use a non-native charger?
If possible, you should use the charger that comes with the gadget, since its parameters are usually tailored to a specific model. Otherwise, you need to make sure that the charger you are using is approved by the manufacturer. Cheap options from Amazon or eBay can ruin your phone. There have also been several cases of cheap chargers catching fire.
Do not leave a lithium-ion battery in a completely discharged state for an extended period of time. Try to always maintain the charge level around 40-50%.
Such batteries, if not used, self-discharge by 5-10% per month. If you completely discharge the battery and keep it in this state for a long time, it may turn out that in the end it will not be able to hold a charge at all (it will become completely unusable).
It is unlikely that someone has a smartphone lying around 24 hours a day and not using it. But with a laptop or spare batteries this may well happen. In any case, you should try to ensure that the batteries are always at least half charged.
No, we are not talking about the morning exercise of the phone owner who decided to check his email while standing in the plank. We're talking about charging your smartphone battery.
The average battery of an average mobile phone is hardly enough for a day of active use. You have to charge in the middle of the day, sometimes in the midst of communication. How can you leave your phone alone for two hours? He will be torn apart by messages. Or not from messages?...

“The question is ambiguous. The myth that you can’t use your phone while it’s charging dates back to old phones. The performance of the batteries of that time directly depended on the charging cycles. If you charge it while in use, the cycle does not occur, hence the battery gradually dies. Modern batteries do not depend on this, and you can safely use your phone while charging.
Yes, it gets hot, but actually that's normal
The power controller and processor can withstand very high temperatures up to 150 degrees and above. Another thing is the comfort of use, as well as the integrity of the manufacturer. Elements of high-quality assembly are characterized by good heat transfer and a high melting point of each part.
Chinese budget models do not guarantee that the plastic inside will not melt, that the board or any other part of the device will not be damaged.
Here is an example of using low quality plastic. The damage is not critical, but there was melting, which means the owner inhaled toxic fumes at a minimum:
It should also be noted that there is a risk of mechanical damage to the charging socket. It’s easy to accidentally tear off the fastenings of the same micro usb to the board by pulling the charging cable at a certain angle.
This is the most popular problem with which people contact the service center.
It can be treated by replacing the connector or resoldering the old one. It costs from 500 to 1500 rubles and requires mandatory disassembly of the device and removing the board from the case. Considering that many modern phones are disassembled by unsticking the display, the usual, from the master’s point of view, work of replacing the power connector turns into a rather labor-intensive task with a high risk.”
Surely many of us have heard that you cannot talk on a mobile phone while it is charging. But only a few know why this is not recommended.
Website editors "So simple!" I decided to look into this issue and inform my readers about the possible danger. Be careful, take care of yourself and your loved ones!
Why can't you use your mobile phone while charging?
When mobile phone While charging, it gets very hot. Even if the device looks as usual on the outside, you don’t see what’s going on inside it. Be careful, even if you have been using the device for a long time and have confidence in it. If the gadget has a small manufacturing defect or there are frequent voltage drops in the network when you charge the phone, - mobile explosion danger increases many times!
There have been cases more than once when a charging phone exploded during a conversation. The outcome is terrible: burns, maxillofacial injuries, burst eardrum, vision problems. The consequences can be very different, but all are equally dire.
Watch how children use gadgets, as they often do not look away from playing on their mobile phone even while it is charging, which is also unsafe.
Safety precautions when charging a mobile phone
A very useful invention. However, it must be used extremely carefully.
In the modern rhythm of life, smartphones have become indispensable assistants and information centers.
Technologies are developing very quickly - every year some innovations and technologies appear that simplify the user's life. For example, let’s remember a fingerprint or iris scanner, a facial recognition system and actively developing technologies artificial intelligence. Despite this, in terms of autonomy and batteries There hasn’t been much progress - even the latest expensive flagships are not able to provide two days of active use of the device. Today we’ll try to figure out whether it’s possible to use phones while charging, and what potential dangers this can bring.
Battery heating
The first and most important probable problem of the situation described above is. When using a smartphone and charging it at the same time, a high load is placed on the battery. On the one hand, it gives off energy, on the other, it receives, so strong heating is possible.
The pattern is simple - the higher the load on the battery, the stronger the heating. The gadget will be especially hot in heavy games and multitasking mode, when the 4G mobile Internet is activated and the display brightness is set to high. It is important to note that the highest heating is usually seen at the outlet, as this is where the current is highest. When charging from a power bank or car, the temperature of the device rises so much.
The conclusion is simple - it is undesirable to use the phone while charging due to its possible heating. If this does happen, protect the batteries from overheating.
Charging speed
It is logical that using a smartphone while charging requires energy - it is both wasted and replenished. Thus, the devices will grow significantly. This must be taken into account if you need to quickly replenish the device's battery.
Other hazards
It should be noted that there are very rare, but truly dangerous situations. Unfortunately, news periodically appears in the media about the deaths of smartphone owners when they use them in the bathroom. Falling a plugged-in electrical device (not just a telephone) into water often has fatal consequences.
Results
It is not advisable to use a smartphone while charging - the phone often heats up and the charging speed decreases. In most cases, nothing bad will happen, but it is very important to take precautions and be alert.
