Get a low battery or full charge alerts from your watch on your paired device
A simple app to let you know when you watch is running low on battery or when it is fully charged. Install the app on both your Android and Wear OS device, set the level you want to get alerted.
In order for the app to work both devices must have Battery Alert installed and opened at least once to initialize communication.
To only receive alerts on your watch toggle the setting "Wear Only Alert"
To only receive alerts on your phone, block notifications for Battery Alert inside Google's Wear OS app on your phone.
Your watch may be unable to send low battery alerts while in battery saver mode so make sure you set the level above where it would turn on automatically.
If you are using Android Wear 1, please be patient for the app to transfer to your watch and contact Google Play if you are having trouble.
