If you install either Battery Notifier Pro BT (For Android 9 and under) or Battery Notifier BT Free (For Android 9 and under) on a device running Android 10 or higher, you may get a notice that says "This app was built for an older version of Android and may not work properly. Try checking for updates, or contact the developer".
Even though Battery Notifier Pro BT and Battery Notifier BT Free are meant for devices using Android 9 or under, it still may work on Android 10 and higher on some devices if you still want colored notifications in the status bar. After buying an Onn tablet from Walmart with Android 10, and after downloading the original Battery Notifier BT Free from Google Play, the colored battery level numbers show up just fine. The only way to know for sure if it will work on your device if you still want to see green, as well as blue, orange and red numbers as the battery level drops is to try it.
Unfortunately, mainly because a lot of devices like Samsung have their own special tweaks to Android including their own UI or overlays, some devices will either show nothing in the status bar or a white square. For these devices you need to use the 2020 version with white only notifications, either Pro or free, which is 100% compatible with Android 10 and up.
IF YOU BOUGHT BATTERY NOTIFIER PRO BT, GET THE 2020 VERSION FREE!
Because Google did not let us update our current app for Android 10 and up and keep colored numbers in the status bar, we created a new app with white only notifications and one that was 100% compatible with Android 10 and up. Since it is a new app, if you previously bought Battery Notifier Pro BT, you will be asked to purchase the 2020 version. We do not feel this is right. So if you previously bought Battery Notifier Pro BT, before buying the 2020 version, send us an email from within the app (Send feedback) so we can verify your purchase, ask for a promo code, and we will send you a link with a promo code to download Battery Notifier Pro BT 2020 for free.
