After Apple has come out with a statement that iPhone is surprisingly slowing down their device due to battery draining issues, Android is also not very far from it.

Even Android users can face the same issue and they might don’t know what to do.

If you are using a smartphone then the battery is one of the major things and as time passes, the battery of Android devices is on much more demand in the last few years. After regular use of your device, you might see some degrading performance on your device.

So to help you out from this situation, I have come up with this blog. Here I will guide you on some effective ways on how to calibrate battery on Android phone and achieve longer battery life.

What is calibrating a battery?

If you are an Android user then you should know that Android OS has a feature called Battery Stats that tracks the capacity of the battery whether it is full or empty.

In this, the problem starts frequently when it becomes corrupt and it begins to show wrong data, and many times the device turns off before it reaches to o percent.

And if you calibrate your Android device then it means that you are correcting the information and your battery begins to show the correct or real result.

Generally, if you see it as a whole then calibrating the Android battery means it helps your Android OS to correct the information that is reflecting wrong.

If you go in deep then you can know that you cannot calibrate the battery itself because it is only a cell, which stores power and then discharges.

But as the battery is a lithium-ion battery so it contains a printed circuit board (PCB) that works as a protection switch to stop exploding or deep charging.

Should I calibrate the battery?

Many times the problem is not only due to battery and this is so then you should look for other reasons. When the problem is big then you should take your phone to a repair shop or if a battery replacement is required to replace then go with the original third-party battery.

If the battery is having some problem then it’s better not to go with that battery for long as it can only give you headaches. In fact, you should also keep in mind that there are several other reasons that can lead to battery problems.

When your phone faces a problem in charging then it can be due to the charging port, so it’s better to check your charging port once.

Even some other conditions can make your device’s battery drain fast like if you have updated firmware of your device.

In this situation, you have to clear the cache partition to get rid of the problem.

But there are a few things that you should do before you begin to calibrate your Android battery.

Check the below steps for more details.

  1. Check if your Battery is the problem

If your device supports a removable battery then you can take it out and just check whether it is swollen or bloated or something like that.

These things can indicate that your battery is damaged and in this situation, calibrating will not help you anyway.


Its simple method is you have to replace the bloated or swollen battery when there is physical damage or even you can take it to repair shop.

As nowadays, the removable battery is seen very less as all the Android devices are coming with a non-removable battery.

  1. Clear cache partition

While upgrading your Android OS to any new version or while flashing a custom ROM, a battery-draining issue is a common thing.

So, in this condition, battery calibrating should be done but before that, you should clear the cache partition of your Android device.

To do this, reboot your device into recovery mode, move to “Wipe Data/Factory reset” and then click on “Wipe Cache Partition” option

After this process is over, you can now move further to calibrate your Android battery.

These entire steps work effectively as it deletes and reset the battery stats database. Also, remember that irregular charging of your device sometimes goes beyond your expectation and it starts to show the wrong battery level.
