About this app

For Android 9 and under - Colored status bar numbers with low and full alarms

Green, blue, orange and red status bar numbers can be customized to display at the percentages you want. Optional yellow smiley face charging icons. Low & full battery notifications.

(For Android 10 and up download Battery Notifier BT 2020.)

IMPORTANT!!!
Battery Notifier BT will not stop working on its own. MOST Android manufacturers have aggressive battery saving settings which shut down apps running in the background by default. We suggest turning off all battery saving/power saving settings. Also, find the Android setting on your device to "optimize" the battery for apps and TURN IT OFF for Battery Notifier BT. If you update to a newer version of Android, you need to make these changes again after the update. The update may also add a new setting called "Duraspeed" which also shuts down apps unless you make an exception.

NOT FOR BLUETOOTH: BT does NOT stand for Bluetooth, and this app has nothing whatsoever to do with Bluetooth. (BT is short for "Big Text" the original name of the app.)

NOTICE: The original Battery Notifier BT is NOT 100% compatible with Android 10 and up. However, if you have Android 10 or higher, and you still want colored numbers in the status bar, the original Battery Notifier BT MAY or may not work on your device. The only way to know for sure is to try it and see.

If your device has Android 10 or up, Battery Notifier BT 2020 is optimized for those devices. It includes white only notifications in the status bar required by Google going forward.

MALWARE NOTICE: Google Play is the only place authorized to carry our apps. If you installed an apk from some other site, it might have malware.

I've always liked this app, but was very disappointed to find out that its not compatible with my new phone that uses Android 10 platform. It only works with Android 9 or less. But I think I found the version that will work with my phone. The icon for the program looks almost identical except it's in black and white. I hope this is the same developer because this is a decent app!

Yes, Battery Notifier BT Free 2020 is also made by Shkil/larryvgs. Starting with Android 10, Google decided notifications in the status bar could no longer be multi-colored, and they could only be white. We were not allowed to update the previous app, and had to create a new 2020 app with white only notifications.

This is a great app, I've been using the free version for years, and have grown to depend on the changing colors of the charge percentage as my battery gets dangerously low. The developer is very helpful and extremely knowledgeable, responding immediately to my questions - regarding the free version, no less! Highly recommend!

Works perfectly, the app notification itself shows the power which is genius, its very accurate, easy to use, and can give notifications when power is low which is amazing. Personally i have relatively cheap headphones that work perfectly except one minor problem: when at low battery they blare into my ears like an air raid siren. This app was able to fix that because i was able to set a notification that its at 25% while the headphones go off at 20%. Great app had no problems with it
