On the LG device, mobile data is not only consumed during active use, but also in the background. With many installed apps, this can be several gigabytes. If apps do not need to be updated in the background, the data saving mode can be activated on the LG, which limits background activity.

For the data saver mode, selected apps can be added to the exception, which can still use the mobile data without restrictions despite the activated data saver mode.
