Hi, unable to turn on my background app refresh option. What can cause this and what can I do to solve this problem? I'm unable to to hear my whats app notifications.

Greetings Ksalandy,

As outlined in the error message showing in the screenshot you provided, you'll need to turn off Low Power Mode to enable Background App Refresh.

Low Power Mode reduces or affects these features:

5G (except for video streaming) on iPhone 12 models

Auto-Lock (defaults to 30 seconds)

Display brightness

Display refresh rate (limited up to 60 Hz) on iPhone and iPad models with ProMotion display

Some visual effects

iCloud Photos (temporarily paused)

Automatic downloads

Email fetch

Background app refresh

Use Low Power Mode to save battery life on your iPhone or iPad

Take care.
