GSam Battery Monitor helps Android users identify apps and device functions that consume battery resources. Its App Sucker view lists resource-using apps and allows sorting by power use, CPU use, sensor time, and wakelocks. The app estimates remaining battery time from recent and historical usage. Charts can place battery level beside GPS, Wi-Fi, screen activity, temperature, phone signal, and CPU use. Home-screen widgets and customizable alarms cover charging states, temperature, and battery health. The free plan is free and contains ads. A Pro plan has no listed price and adds tablet-optimized views, estimates for tablets and large-screen devices, and downloadable or user-created icon themes. Detailed statistics on Android Lollipop and later require manually enabling Enhanced Stats through ADB. Some statistics may remain unavailable because of Android’s collection behavior. Google Play lists ads and collection or sharing of app activity, app information and performance, and device or other IDs; data is listed as not encrypted or deletable.
