Healthy Battery Charging https://f-droid.org/packages/biz.binarysolutions.healthybatterycharging Healthy Battery Charging alerts you when to plug or unplug your phone from the charger to improve battery life. The app itself is optimized for low battery consumption, running in the background and checking the battery level every 15 minutes. The exact timing of these checks depends on the Android operating system, which may schedule them alongside other tasks or delay them in sleep mode. As a result, the battery level may slightly exceed the high threshold while charging or drop slightly below the low threshold while discharging before you receive a notification.
