AccuBattery

What AccuBattery is

AccuBattery is freemium Android software for monitoring battery health and performance. It estimates charge capacity in mAh and wear per charge cycle, displays live charging and discharging information, and records charge and discharge sessions with estimated wear. A charge alarm can notify you at a chosen percentage so you can unplug the phone to help reduce wear. The app reports battery current, charge speed, and power use in real time. It assigns realized total battery drain to the foreground app, so background processes may be attributed to that app. App-usage statistics access is optional, although some per-app information is unavailable without it. The free plan costs nothing and provides 24 hours of historical session access. Premium is unlocked through an in-app purchase and includes an overlay showing battery current and CPU usage while another app runs; its plan lists the last 150 historical cards. Some Android devices do not provide usable current data, preventing capacity estimates and other dependent features.
