Battery Calibration is a tool that lets you calibrate the battery on your Android device, the battery can last less than it should due to its possible miscalibration.
To be able to use the application, the first thing you have to take into account is that the device has to be 'rooted'. If it isn’t 'rooted', it will be impossible to carry out the calibration procedure as it includes removing the 'batterystats.bin' file from your system.
Shortly after removing the file, your device's operating system will create a new, completely clean, 'batterystats.bin' that will not contain any prior information. In this way, the battery will be perfectly calibrated.
Battery Calibration is a very useful tool with which you will be able to have better information regarding your battery. It’s important to point out that the application does not increase how long your battery lasts, but rather allows you to have its real data.
In other words, by using this application you won't have longer battery duration, you'll simply know exactly how much life it has left, without false readings.

The APP has a virus and is a spy, Google PlayProtect warns you about this upon installation.
I really liked it thank you for everything
Very good
The application between once it starts it does what is required and once it stops. In addition, my device considers it as a spy virus and asks to delete it by force
Excellent did what no other could do, there are some negative comments that are actually positive, they just didn't know how to give it stars hahaha, thank you very much for the app
3500 battery capacity, 100% charge, all applications closed. The application writes 56 minutes of operation left, the battery condition is good. Understood, accepted.
