Battery Whitelist
The Android battery optimisation settings can sometimes infringe on Carv’s ability to connect to GPS signals, causing gaps or inaccuracies in the data from your run. They can also cause the Carv app to be killed in the background which will stop it from recording your runs.
The Carv app has a "Battery whitelist" option in the Settings screen. This will allow Carv to be excluded from your phone's battery optimisation settings.
To access this head to the Carv app and then select: More > Settings > Battery whitelist > Toggle ON
If you cannot see the Battery Whitelist option, ensure that you have the latest version of the Carv app.
App Locking
For some Android devices, you have the option to "Lock" your app. This prevents your device from automatically closing the Carv app, which will interrupt your run tracking. Please see below for how to lock your app on different Android models.
Samsung Devices
- Open the multitasking pane, otherwise known as 'app switcher'.
- Tap the Carv app logo top center, and select 'Keep open'.
- Please note that depending on the version of Android, it may also be called 'lock the app'.
See below for an example of this process:
OnePlus Devices
To lock the Carv app on a OnePlus device with Android version 9:
- Go to your recent apps screen, also known as the overview screen. You can normally access this either by swiping up or by selecting the square in the bottom right-hand corner of your screen.
- Once there, depending on your model, you will either need to select three dots in the top right-hand corner followed by "Lock" or alternatively there will be a padlock icon in the top right-hand corner which you can select.
