The app uses Bluetooth Low Energy (BLE) and will have minimal impact on your mobile phone battery, especially if you normally have Bluetooth enabled.

If your phone battery is draining much faster than usual, you can check how much battery the app is using compared to other apps. You can usually find this on your phone by following these instructions (the steps may be slightly different, depending on your phone):

  • Apple iOS: Settings -> Battery

  • Android: Settings -> Device Care -> Battery 

If your phone shows that more than 5% of your battery life is being used by the app, please report a technical problem . To find out why this is happening and to try to help you, please include the following information:

  • Percentage of battery used.

  • The make and model of your phone (for example, iPhone 8 or Samsung Galaxy S8).

  • The operating system (for example, iOS 13.5 or Android Marshmallow v6.0).
