Battery Full Alarm & Health

Battery Full Alarm & Health rings when your phone reaches the charge level you choose, so you can unplug at the right moment. The alarm starts at 80%, where many people prefer to stop charging, and you can set any level from 50 to 100%. It also warns you when the battery runs low, and shows the current, voltage, temperature and time to your target while you charge. HOW IT WORKS • While the charger is connected, a silent ongoing notification shows the battery level, the charging current and the time to full. This notification is how Android lets the battery full alarm keep watching in the background. It goes away when you unplug. • When the battery reaches your target, the alarm rings with your alarm sound and vibration. Tap Stop in the notification or on the alarm screen. • For the alarm to start by itself when you plug in, allow the app to run in the background (no battery optimization). A guide in the app shows how. Without it, a "Charging. Tap to monitor" notification appears, and one tap starts the battery monitor. • The low battery alarm checks about every 15 minutes while you are not charging, so it rings within about 15 minutes of reaching your level. • The app does not change how your phone charges. It tells you when to unplug. WHAT YOU GET • Full charge alarm at any level from 50 to 100% (80% by default) • Low battery alarm from 5 to 50%, with a 5-minute snooze • Your alarm sound, vibration, and ring until stopped (up to 5 minutes) or ring once • Charging status: battery level, charging current in mA (+ while charging, − while running on battery), voltage, temperature, charger type (wall, USB, wireless or dock) and the time to your target and to full • Battery health: the health status Android reports, the charge cycle count on phones that report it (Android 14 and newer), the estimated capacity in mAh and the highest temperature seen • Temperature in °C or °F • Dark theme, tablet layout and screen reader support PREMIUM • Charging history: every charge with start and end level, duration, highest temperature and the alarms that rang • Charts of level and temperature during each charge • High temperature alarm (38 to 50 °C), checked constantly while charging • Quiet hours: alarms at night appear without sound • Home-screen widget with the level, charging state and your target • No ads Premium is a one-time purchase.

WHO IT IS FOR • People who like to unplug at 80 or 90% instead of leaving the phone at 100%. • Overnight chargers: an alarm by the bed, or silent alarms in quiet hours. • Owners of older phones who watch temperature, current and estimated capacity. QUESTIONS Why is there a notification while I charge? Android requires a visible notification when an app keeps working in the background. It is silent, appears only while the charger is connected, and disappears when you unplug. Why did the battery full alarm not ring? Check that notifications are allowed and that the app may run in the background (Settings > Battery optimization in the app). Some phones also stop apps with their own power saver; the in-app guide shows what to change. Does the battery full alarm stop charging at 80%? No. Android does not let apps control charging. The app rings so you can unplug. Is 80% better for my battery? Many people prefer to stop charging at 80%. The app makes no promise about your battery; it rings at the level you choose, and you decide. Why is the cycle count missing? Android offers the cycle count from Android 14, and only on phones whose maker reports it. Otherwise the app shows "Not reported by this phone". How is the capacity estimated? From the charge counter Android reports, divided by the battery level, over several charges. It is an estimate, and some phones do not report a charge counter. What about privacy? No account. Your battery readings and charging history stay on your phone, and the app works offline.
