Full Battery plays an alarm the moment your battery reaches the level you choose, so you can unplug it instead of leaving it charging all night.
Set it to 80% overnight to protect the battery, or 15% when you are in a hurry before heading out. Both work the same way.
80%
The level worth stopping at
Or any other level you pick
Lithium batteries age faster when they sit at 100% for hours. Charging to around 80% and unplugging is the simplest way to keep a battery healthy for longer. Full Battery is the reminder that makes that habit possible without watching the screen.
See what it doesA charge alarm is only useful if you actually hear it and it keeps running. That is where the work went.
The alarm plays through the alarm channel, not the media channel — so it is loud even when your ringer is silenced. It can also read the level out loud a few seconds in, which helps when the phone is charging in another room.
10–100%
80% overnight to protect the battery, or 15% in a hurry before heading out — both are one drag of the slider.
The alert survives a reboot. You don't have to remember to open the app again after restarting your phone.
Quiet hours turn the night-time alert into a silent notification instead of a sound, and several settings profiles let you switch setups without rebuilding them.
Set it once. The app does the watching, and tells you when to come back.
Drag the slider to the percentage you want to be told about, pick the alarm sound, and decide whether it should vibrate.
The app watches the charging level in the background. A small running notice stays in your shade, because Android requires one while an app observes charging.
Stop the sound from the notification, from inside the app, or tap Keep charging to full if you changed your mind and want it to run to 100%.
Nothing loads from YouTube until you press play. Watch on YouTube instead.
A short walk-through: picking the level you want to be told about, choosing the alarm sound, and what the alert looks like when the battery gets there.
Captured on a phone, not drawn in a design tool. This is what you get.
No account, no sign-in, no server. Your settings never leave your phone, and the app cannot read your files, your location, or your messages.
Each of these is written into the privacy policy or is a limit of what Android allows — not marketing copy. Reviews from real users will appear here once the app is on Google Play.
The advertising system stays completely dormant until you tap "Watch ad" yourself. If you never tap it, no ad request is made and no advertising identifier is ever read.
Ads stay asleep
We have no backend server. Your alert settings, profiles and appearance live in Android's private app storage and are gone when you uninstall.
Nothing to collect
It cannot stop the charging itself. No Android app can do that without root. It reminds you to unplug, and it does that reliably.
What it does not claim
Full Battery is free on Google Play, for Android 8.0 and above. No account, no sign-up, and nothing about you leaves your phone.
