Wear Battery Full is a useful utility for your Wear OS watch that lets you know when your device is fully charged. It is useful for those who need to keep their watch in tip-top shape and to avoid having to remember to check the battery level every time they connect or disconnect their device from the charger.

The app can alert you to a charge that is about to finish, so you can stop using the device until it is fully charged. You can also set an alarm for when the battery is at 100%, so you will be notified when the level is reached. You can also choose to turn off the notification for the battery level.

To use the app, you first need to install it on both the phone and the watch. Then, run the app for the first time on the phone to activate it on the watch. You will be asked to grant permissions for the app to work properly, and you need to accept them to continue.
