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.

I think it could help me control my battery's performance and keep an eye on its performance.
I liked it very much thank you for everything
Very good
The application sometimes works and performs as required, and other times it refuses to work. Additionally, my device considers it spyware and insists on forcibly deleting it.
Excellent, it did what no other could do. There are some negative comments that are actually positive, they just didn’t know how to rate it haha. Thank you very much for the app.
Battery capacity 3500, 100% charge, all applications closed. The app indicates 56 minutes of operation remaining, battery condition is good. Understood, noted.
