The NHS COVID-19 app is no longer in use and the Isle of Wight trial has now ended. This is archived information from 18 June 2020. If you still have the app, please uninstall it.

The NHS COVID-19 app uses “Bluetooth Low Energy” and will have minimal impact on your mobile phone battery, especially if you normally have Bluetooth enabled.

If you find that your mobile phone battery is draining much faster than usual, you can validate how much battery the NHS COVID-19 app is using compared with other apps.

This information can normally be viewed on your mobile device by following the below instructions (please note that precise steps can differ slightly depending on device):

  • Apple iOS: Settings -> Battery
  • Android: Settings -> Device Care -> Battery 

Battery optimisation may negatively impact the apps effectiveness. Please consider disabling it. That can normally be done by following the below steps (please note that precise steps can differ slightly depending on device):

  • Apple iOS: Settings -> Battery -> Low Power Mode
  • Android: Settings -> Device Care -> Menu -> Battery optimization

If your device shows that battery life is being significantly impacted by the app (greater than 5% battery usage), please report a technical problem on the covid19.nhs.uk website to provide the following information that will help investigations:

  • Clearly state that your technical problem is associated to battery usage and specify the % battery usage of the app that your mobile phone is reporting
  • The make and model of your phone (e.g. iPhone 8 or Samsung Galaxy S8)
  • The operating system (e.g. iOS 13 or Android 9)
