I think the app is great and does what it says, but last update wanted permission to access my home network and location. For a program that has only the function of calibration of the battery there is no need to invade privacy. Used to love the app. Sadly had to uninstall. Here we provide Advanced Battery Calibrator V 3210 for Android 4.1++ There are well known problems with Android OS and the reported maximum battery capacity. This maximum battery capacity is used by android OS to know when the battery is fully charged.
Advanced Battery calibrator will fix this problems and make Android OS see your real battery capacity allowing it to be charged to its real full capacity.
Advanced Battery Calibrator works specially well with its sister app "Battery Life Repair" and it has been designed to take full advantage of it by sharing information between both applications. If you want to keep your battery healthy use both applications and take advantage of its integration.
Calibrate your battery today with the top one application on the store and experiment a real improvement on your battery.

Actually don't know yet. Asked me for review before I could evaluate. Never understood why developers did that.
