What AccuBattery is
AccuBattery is an Android app for monitoring battery health and performance. It estimates charge capacity in mAh and battery wear per charge cycle, and displays live charging and discharging information such as current, charge speed and power use. The app records charge and discharge sessions with estimated wear, while a charge alarm can remind you to unplug your phone at a chosen percentage. The free plan is listed as free and provides 24 hours of historical session access. Premium is unlocked through an in-app purchase; its listing currently shows the last 150 historical cards and includes an overlay for battery current and CPU usage while another app runs. Per-app drain is attributed to the foreground app, so background activity may be assigned there instead. App usage statistics access is optional, but some per-app details are unavailable without it. Some Android devices lack usable battery-current data, which can prevent capacity estimates and other current-dependent features. AccuBattery's maker is based in Rotterdam, Netherlands.
Who it suits
AccuBattery may suit Android users who want to track battery sessions, estimated wear and charging behavior. Users interested in per-app details should note the optional usage-statistics permission and device data limitations.
