Do’s and Don’ts of Android Smartphone Battery Calibration

If you go back a couple of years ago, you should have heard from the seller when you bought the battery to charge the battery fully and then 100% before using it. You even heard that every few months, for example, every month or at least every three months, calibrate the phone’s battery. But what about the calibration of the battery on the Android phone? Is it still necessary to calibrate the battery every time? Below will teach you both wrong and right ways of calibrating your Android phone’s battery.

What is Android phone Battery calibration?

To understand the battery calibration, you first need to know a little about battery handling. In fact, each battery has a smart chip, which signals the amount of battery charge by sending a signal. Smartphone receives this signal and displays the percentage of charge on the phone.


In this case, the chemical elements of the battery, such as lithium or nickel, are the same elements that store energy in the battery. Now, in order for this smart chip to accurately measure the amount of energy stored in the battery, you need to learn the capacity of the battery, and this is the key to learning. If the battery charge reaches 0 and then fully charged to 100%, the chip will learn the battery capacity.


So, when the battery is charging, we’ll charge it again and repeat it over and over again, the smart chip gets confused and cannot correctly recognize the charge percentage. So, for the chip to work, it’s said that you have to calibrate the battery every now and then. (Wait until the end of the article because the phones are completely different.)

How to calibrate the battery?

The process of calibrating the battery is very simple. Just follow these steps:

1. You must first empty the battery completely. So use enough of the battery to turn off the phone.
2. Now turn on the handset again to turn itself off by itself. We do this because it always stores a little energy, which should completely eliminate this stored energy.
3. When the battery is completely discharged, plug in the Android phone in the same silent mode and wait for 100% charge.
4. When the battery is 100, disconnect the phone and turn it on. If you find that the battery has not yet reached 100%, plug it back in and wait for the battery to reach 100.

With this, the smart chip is calibrated and fully captures the actual battery capacity.


Note: Using Quick Charge is not a problem, but it is not recommended to increase battery life.

What is the calibration of the battery?

Calibrating the phone’s battery basically only displays the correct percentage of charge, and contrary to the misconception that may be in the minds of many people, it has no effect on improving battery life! In fact, this is the only false idea of the years that there was still no lithium ion battery and smart chips and smart sensors on phones and laptops.


Calibrating the battery does not even measure the health of the Android battery. In fact, charging and discharging batteries (known as Wear and Tear Specials) affect the disassembly of the device’s calibrated battery.

Delete BattreryStsts.Bin file; Next false belief

Another misconception that the battery is calibrated, especially on Android phones, is to remove the BatteryStats.Bin file . There are even many Android applications that claim they can improve their health by calibrating the battery, but the fact is that deleting this file has no effect on battery life or even the accuracy of the displayed number as a percentage of battery charge. The interesting thing is that this file is completely reset each time the battery is charged.

There is usually no need to calibrate the battery

With all the explanations we have to say that most Android phones do not need to calibrate the battery because the smart battery chip shows you the correct percentage along with Android’s intelligence in determining the correct percentage of battery. In fact, intelligent algorithms and sensors on Android and iOS devices themselves calibrate it without having to charge and discharge the battery. In essence, the handset is calibrated after getting low battery. So you do not need to calibrate the phone.

When do we need to calibrate the battery

Only when we need to calibrate the battery is when, for example, the battery is shown at 30%, but at least one charge rate reaches 5 and then turns off. Also, if the battery is unplugged and after 10 minutes of charging it reaches 90% (faster than normal charging), then the battery will be immediately calibrated, then you need to calibrate the battery.


Another time we need to calibrate the battery is when you do not turn on the phone for a long time, for months, for example. Except for these, we do not recommend the full discharge of the battery.

Final recommendation: Rarely calibrate the battery

You may still be faced with people who advise you to calibrate battery every few times, but it will reduce battery life as it requires a full battery drain. In fact, as the number of times the battery is completely discharged, its lifetime goes down significantly.


Therefore, we recommend that you do not calibrate the battery, even if you encounter a problem with displaying the wrong battery. We also reaffirm that calibrating the phone’s battery does not have any effect on its lifetime.


Instead of recharging and discharging the battery, take tricks and tips to increase battery life . For example, we can mention the simplest points that increase battery life:

• The use of dark themes, especially on phones with OLED displays
• Turn off Wi-Fi auto-activation mode
• Limit the implementation of apps running in the background
• Disable Google Assist
• Monitor and remove (if necessary) programs that use excessive battery power
