Modern mobile devices are very advanced in careful energy consumption, new standards and technologies are being developed, however, the problem of battery life and, consequently, the use of the gadget itself is still acute.
Most mobile devices have a removable battery, which allows you to quickly and easily replace it if it fails, but there are some where this is impossible, for example, in Apple devices, which is an absolute disadvantage. Frequent cycles of improper charging of iOS devices lead to malfunctions of the controllers, both the battery itself and the device. For example, when an iPhone or iPad shows that you still have 5-7% left, but the next moment the device turns off, or the battery level hangs at 98% for a long time during the charging process.
To prevent an iOS gadget from “deceiving” you and giving you a bad surprise, it is possible to calibrate the controllers - this is a forced process that brings the battery and device controllers to optimal condition. Calibration is recommended by computer manufacturers and will be useful for all devices, not just Apple ones.
The lithium batteries that are supplied with the iPhone and iPad will not receive any “miraculous” benefits from calibration, but they will normalize all sensor indicators, which will undoubtedly increase the battery life.
How to calibrate batteries in iPhone and iPad:
1. Completely discharge your iPhone or iPad so that the gadget turns itself off. This can be done quickly by playing on your device, with the screen at maximum brightness, the Internet turned on and the sound at full volume. Yes, completely discharging lithium batteries is categorically not recommended, but it will not happen as the gadget will turn off at 0%, which does not correspond to the actual lack of charge in the battery.
2. After complete discharge, you need to charge the mobile device 100%; it is better to use the original, standard power supply.
3. After the iPhone or iPad screen displays 100%, leave the gadget connected to the charger for another hour.
4. Disconnect the device from charging and use it as always until the next full discharge to zero, but without recharging.
5. Repeat steps 2 and 3, after which you will receive an iPhone and iPad with calibrated batteries and sensors.
Short battery life of a smartphone is one of the most common problems and disadvantages of most models. With iPhone, the problem occurs over time, or when the phone is used for a long period. Sometimes all that is needed to fix the problem is to calibrate the battery to improve its performance.
Firstly, why is this process necessary? Battery calibration (sometimes called a "reboot") is an important part of phone support. Without this procedure, the phone may begin to incorrectly read remaining charging data, as well as not optimize power consumption well and record a sudden failure with available charge, which until recently seemed quite optimal.
Factors such as software bugs, updates, and just regular use require this calibration. The process is not complicated, but takes a little time. However, it's worth it at least once a month, especially if you use your phone a lot.
Education
Before you begin calibration, you need to take a few preliminary steps. This excludes certain features and services, which may then be reactivated.
Disabling localization services
Go to Settings > Privacy > Location Services and move the slider to the off position.
Disable background refresh
Go to Settings > General > Background App Refresh, then select the same option from the new menu and tap Off.
Decrease display brightness
Again, go to Settings > Display & Brightness > move the slider to the far left.
Disable automatic updates
To do this, go to Settings > iTunes & App Store > move the slider to Off in the Ypdates row. In the Settings > Battery menu we can check whether the power saving mode is enabled. It should be turned off.
How to calibrate the battery on iPhone?
Now the actual calibration process begins. The whole procedure involves several steps and requires patience.
Step 1: Battery depleted.
The phone battery must be completely discharged. This can be done through the most active use of Eden, Play Videos, Play Games and much more.
Step 2. Wait 3 hours.
As soon as the phone turns off, you need to wait at least three hours.
Step 3: Charge your phone.
Now you need to properly recharge the battery. This means using the charger from a wall outlet rather than the cable on your computer. It is also important to use your own charger and cable. You need to allow the phone to restart at least two hours after it shows that it is fully charged.
Step 4. Repeat the discharge.
Now repeat the procedure. Let your phone drain completely again with normal use or with movies and games.
Step 5. We wait another three hours.
It is preferable to leave the phone turned off overnight.
We repeat the same charging process and the phone is ready. You can now reactivate the features you initially disabled and use your iPhone as usual.
There is little use for gigahertz processors, megapixel cameras and other products of the high-tech world if there is no energy in the smartphone batteries for them. Extending the battery life of a gadget is perhaps the most important task posed today.

And, despite the fact that Apple engineers more or less successfully solved it, we too can and must make our contribution to the common cause.
No, of course, no one forces you to chew on the granite of applied science and acquire new skills. If you have enough money to buy a flagship, it won’t be difficult to save up and, fortunately, an extra 100-200 grams in your pocket is not a hindrance. Moreover, in iOS 7 A lot have appeared to optimize energy consumption, a good half of which are capable of operating in automatic mode.
However, the unpleasant truth is that battery efficiency is not constant and greatly depends on the mode in which the device is used. Simply put, the batteries need to be calibrated periodically - a kind of analogue of resetting to factory settings, which will only benefit the i-gadget’s energy system.
How to Improve iPad or iPhone Battery Life
1 . Launch any application on your iPhone or iPad, preferably the most resource-intensive one. And go have tea at a restaurant on the other side of the city, and take a walk - during this time the device will be completely discharged and turn off by itself.
2 . Battery Level 0% – Connect the charger and charge your iPhone or iPad to 100%.
3 . The treasured numbers appear on the display, but do not disconnect the charger for at least another hour.
4 . Again, do your best to drain the battery quickly. An important point - while the energy is flowing into nowhere, you need to stay away from sockets. No contact with the charger, even for a second, otherwise the “magic” will be destroyed.
5 . Repeat steps 2 and 3 again, charge the iOS device battery and let it sit.
6 . Calibration is confirmed, you can use the tablet as usual.
The harsh truth of life is that the batteries of even such advanced devices as the iPhone or iPad Air have a very limited lifespan. You have to pay something for the compact size and affordable price, don’t you? Over time, they degrade and the time between recharges will become shorter and shorter, the battery will tend to discharge spontaneously and in the end it will simply have to be replaced. But before that, by regularly carrying out simple calibration, it will be possible to squeeze the maximum possible out of its working module.
The program shows changes, but in reality there are none
Before starting the procedure, I recorded the values in coconutBattery: the battery state is about 83% , maximum capacity - 1631 of 1960 mAh.
After the procedure, the numbers in the application really increased: the battery condition is about 88% , maximum capacity - 1724 out of 1960 mAh.
It would seem that it’s time to clap your hands and run to write the most positive conclusions.
But instead, I started observing the data it produces over a couple of minutes.
The miracle application surprised me: the percentage of the battery status jumped to different values in the range of 80-90%. Therefore, there can be no talk of any accuracy in this case.
Instead, I will use a more realistic source of information that you can trust - “Battery Health” from the Settings > Battery menu:
And it was and remains 87%.
The maximum battery capacity is 87%, it was this way before the experiment and remained the same after it.
This confirms two facts:
▪️ There is no point in calibrating the iPhone battery - we will see this a couple more times later.
▪️ Third-party apps do not have access to real iPhone battery health data.
If you are not satisfied with the battery life of your iPhone, and the number of recharge cycles has exceeded 500, change the battery
Face it, this is a consumable, and it gradually breaks down every second.
iPhone battery controllers keep track of them reliably
How the controller controls iPhone charging
iPhone perfectly controls the charging of its battery, which takes place in two stages: fast charging and trickle charging.
▪️ Fast charging. First, the iPhone loads its battery as much as possible and brings the energy inside it to 80%.
This charging time depends on the power source you are using: a standard power supply, an iPad power supply, Power Delivery mode with a MacBook power supply and a Lightning to USB-C cable.
At the same time, the controller monitors the temperature and reduces the charging speed if it reaches critical values.
▪️ Compensatory charging mode. The remaining 20% of the battery is charged at a reduced current, and the energy level inside it gradually reaches 100%.
This is necessary for the battery. Therefore, even my iPhone 7 with 750 recharge cycles today feels quite normal and even shows “Peak Performance” of the battery.
Battery controllers are calibrated during production
In the past, Apple actually advised periodic calibration of the batteries of its devices. Most likely, it has been in our minds since then experts this concept remains.
However, this never had anything to do with the iPhone. Device controllers with built-in battery calibrated during production and they do not need any additional manipulations.
Only devices with a removable battery need to be calibrated: MacBook and MacBook Pro before 2009, as well as iBook and PowerBook.
Today it's not scary to update iOS
🕐 Update iOS quickly. A couple of years ago, Apple was accused of deliberately slowing down the iPhone with new versions of the operating system.
After this, the company pays close attention to updates and regularly optimizes each next one.
iPhone can and should be updated. It is best to turn on “Auto Update” in the “Settings” > “General” > “Software Update” menu.
🔌 Normal accessories. Cables and power supplies of unknown origin are contraindicated for long battery life.
At the same time, to charge your iPhone, you can easily use the power supply not only from the iPad, but even from the MacBook (we’re talking about USB-C).
High and low temperatures are your enemy
🌡 Beware of temperature. iPhone is best charged and used in temperatures between 0°C and 35°C.
Any strenuous load under conditions that go beyond these limits can be detrimental to the battery.
📲 Charge without a case. Many models of cases (especially new ones) contribute to battery overheating.
If you notice that your iPhone gets warm while charging, the first thing to do is remove the case.
🗃 Store your iPhone correctly. If you do not use your iPhone for a long time, make sure that its battery has approximately 50% energy.
It is best to check its level once every couple of months.
When to change the battery in your favorite iPhone
500 cycles is not always the limit
The problem with most modern gadgets is that the battery drains too quickly. Sometimes they may turn off even though the screen shows a sufficient charge level. What to do in such a situation? Is this a serious problem? If the problem occurs with a new phone, then it is better to return it under warranty. However, if it has already worked for 2-3 years, then it is worth trying to calibrate the battery.
iPhone is the most popular brand, so let's look at how to rehabilitate such a smartphone, restoring its ability to work for a long time on a single charge and, importantly, without failures.
Calibration - what does it mean?
With the advent of touchscreen gadgets, the word “calibration” is heard very often. Many people apply it only to screens, believing that it improves touchscreen sensitivity settings. And this is true, some phones have this option. But, in addition to the sensor, you can also calibrate the battery. iPhone 5s, 6 and other models do not have this function in the menu, so not all users know how to configure the battery (this will be discussed later).
The essence of the calibration process is to zero the controller. The latter is responsible for the operation of the battery, that is, it determines the minimum and maximum charge values. Over time, the battery capacity decreases. Because of this, the controller may not work correctly - it may not fully charge the battery or turn off the phone too early.
When is calibration needed?
You can highlight the main signs that will make it clear that it’s time to calibrate the battery of the iPhone 5, 5s and other modifications.
- The phone began to discharge quickly.
- A sudden change in the charge level, for example, was 40%, and after a few minutes it became 20%.
- Turn off the device by 10-15%.
- The smartphone has not been used for more than three months.
iPhone battery calibration: step-by-step description of actions
Any user can handle battery calibration. The algorithm is simple. It consists of doing two complete charging and discharging cycles.
Step-by-step description of actions:
- Discharge your smartphone. It is necessary to use as many functions as possible in order to drain the battery as much as possible. As soon as the device turns off, it should lie down for 5-10 minutes.
- The next step in calibrating the iPhone battery is connecting to power. For this purpose, a charger and a current source with a constant maximum voltage are used. Do not turn on the device itself!
- Wait until the 100% icon appears on the screen. After this, the phone with the charger connected should be left for another 1-2 hours. After all, the controller may erroneously show the charge level.
- Now you need to disconnect the charger.
This completes the first stage of battery calibration for iPhone 6 and other models. Next, you will need to repeat all the steps described above again. Discharge the gadget to the maximum until it turns itself off. Then charge it again to 100% and leave it on charge for another hour. That's it, calibration is done. Now you can use your smartphone as usual.
Important: do not charge your phone while performing these steps!
How to care for your battery?
You should definitely calibrate your iPhone battery at least once every six months. This will save the user from rapid discharge. But, in addition to this method, there are rules that will help ensure long battery life.
- The smartphone should only operate in acceptable temperatures. Both hypothermia and overheating can cause damage to the battery.
- It is not advisable to constantly keep the device charging if it already shows 100%. It is also not recommended to completely discharge it.
- If no one will use the phone for a long time, then during storage the battery should be charged by 30-40%.
- Use only original accessory (supplied).
Conclusion
Smartphones from the Apple company have proven themselves only on the good side. They hold a charge well, especially compared to Chinese gadgets. But over time, even expensive equipment can malfunction. Therefore, if the iPhone 5 or 6 begins to discharge quickly, then you need to calibrate the battery. There are opponents of this method. These people write that there is no point in implementing two complete charge and discharge cycles. But you can find many reviews in which users claim that after performing the calibration, the battery life of their phone became the same as before. Definitely worth a try. It definitely won’t harm the smartphone.
