5 Apps that Notify You When Your Android Battery Is Full

Unless you use an app, it’s complicated to determine when your phone will be done charging. Even though overcharging your phone won’t make your phone explode, it’s still a good idea to only charge it until it’s reached 100%.

These apps will not only notify you that your phone’s battery is fully charged, but they will also allow you to add something extra. For example, you can personalize the tone of the notification so you won’t have to cover your ears every time you hear it.

1. Full Battery & Theft Alarm


Full Battery & Theft Alarm has a very easy-to-understand interface. As soon as you open the app, it will display the charge percentage. It will also show your phone’s temperature, overall health, and the time until the battery is full.

Tap on the hamburger icon at the top-left to go into the app’s settings. There you can set the full battery level and the low battery level. Don’t forget to tap on the anti-theft option to prevent anyone from unplugging your phone without your consent.


If someone were to unplug your phone, an annoying alarm would sound. It can only be turned off by entering a code you set up when you first install the app. The app will even show you your charge history with time and date.

2. Battery 100% Alarm

Battery 100% Alarm, doesn’t have an anti-theft option like the first app, but it’s still a good option. The app will keep you up to date on how much your battery is charged and how much time is left before the alarm goes off, as you can see in the image below.


You can also set a snooze button for the alarm from one to five minutes. There is a slider that allows you to set the maximum charging limit, whether it’s 100% or less. If you don’t want the alarm to scare you due to the volume, there is also a slider to adjust the volume level as well.

3. Full Battery Notification

Battery Full Notification works silently in the background without showing any signs of life. The app can notify you of the full battery either by sound, vibration or by sending you a text message.


Customizing the alarm is also possible. When you tap on the Ringtone option (in Settings), a “Complete action using” window will appear. You can change the alarm tone either by using media storage from your device or by using any other app you have installed.

4. Full Battery Alarm

Full Battery Alarm has a few extra features up its sleeves. For example, in the app’s main page, besides having bright red as its color theme, it also has a slider where you can control your phone’s screen brightness. To the right you’ll have easy access to the flashlight to light your way as well as info to see the battery’s remaining capacity.


When you use the app for the first time, it will not ask you to enter a password to disable the anti-theft alarm. You’ll need to go to Settings and do it yourself. Once you’re in Settings, tap on the “Auto Enable Theft Alarm” option, and enter your new password. You can also change it later.

5. Full Battery Alert

If you’re looking for an app that keeps things simple, Full Battery Alert is worth a try. Things are not going to get any simpler than this since the app’s main page only features one button. Tap to start and tap to finish, that’s it.


Tap on the cog wheel at the top-right to go into the app’s settings. There you can change the alarm’s ringtone, maximum charge level, alarm delay, vibrate option and if you want the app to start as soon as you plug in the charger.


Your phone may not explode if you leave it charging overnight, but it won’t help keep your battery healthy. With these apps, you’ll help keep your phone’s battery healthy longer.

  1. Is it not possible for an app to stop the charging process once the battery reaches 100%? It could then monitor the charge and when it drops to a level set by the owner resume charging.

  2. how about an app that sends a text every time when the charger is plugged in or out. am thinking this could help someone like myself. i run a WISP (wireless internet service provider) and sometimes wen there are power outages in the locations where our equipment is installed it would be helpful just to know that the particular site is now running on backup power. so the phone will interpret the power outage as charger being unplugged and when power comes back it thinks the charger has been plugged in. the full battery and theft alarm app can be modified to do just that, i think. anyway thanks.

  3. please don’t use the word “hamburger” anymore. hamburger is food and is round shaped. for high tech articles please use “three lines”. simple and more technical, isn’t it?

    1. If you want to most correct, specify “menu” for whatever icon might be used in a screen rather than describing it. For accurate description per your request, the menu icon would have to be described at “3 horizontal lines of equidistant length”. Just say “menu”.

  4. Since every battery app herein described is adware, I take it there are no truly free battery apps.
