What is Battery Calibration?

There is a feature in Android OS called as Battery Stats. Battery Stats generally keeps track of the battery capacity, and determine whether it is empty or full. Many times, it becomes corrupted and displays data which isn’t real which causes the phone to turn off before reaching 0%. When we do battery calibration, we are actually getting the Android operating system to correct this information so that we see actual battery level of our smartphone.

Now, the next thing which may cross your mind is how to know why your battery performance has decreased. Whether the battery is the cause or is it Android system’s calibration.

Before doing battery calibration, we suggest you to check if your battery is okay. If your Android device has a removable battery, then take out the battery and inspect it. Look for swelled up regions, bulges or leaks. If your Android device has a non-removable battery, then also keep an eye for similar occurrences. Keep your device on a table. If it doesn’t sit flat, it is also a sign of swollen battery.

After inspecting the battery, if you are satisfied that it is not the problem, then move ahead in this tutorial for calibrating your battery. If the battery is the cause of the problem, then we advise you to replace your battery with a new one. Always go for original or reliable third party batteries.
