Battery Charge Reminder

Battery Charge Reminder is a background service that informs the user about the remaining capacity of the battery from an arbitrary threshold (e.g. 10%) when discharging. The notification appears in the foreground, even when other apps are open. Battery Charge Reminder is helpful, if the Android system notifications at 14% and 4% are not sufficient and you want to keep the dwindling battery capacity yet in sight during intensive work or play. The notification does not appear permanently, but periodically.
