ScanWatch can operate for up to 30 days on a single charge, depending on your use of the different features of the watch (ECG, SpO2, Notifications, Workout mode, Heart rate, Quick Look, Elevation, Respiratory scan). Note that using the continuous heart rate mode all the time instead of just during activities will deplete the battery much faster. 

A warning message lets you know when your battery level goes down to 10%, and the low battery mode turns on. 

If you don’t charge your ScanWatch and let your battery level goes down to 0%, the power reserve mode turns on. It will allow you to keep using your watch for up to 20 additional days. You will be able to continue tracking your steps and your sleep in this mode. However, you will need to charge your ScanWatch to use all other features (heart rate mode, SpO2, ECG, Workout mode, and notifications).

You can easily charge your ScanWatch using the magnetic charging cable provided with the watch.
