Turn Off The Background App Refresh Feature on Your iPhone or iPad
Your iPhone (or iPad) allows apps to check for new information in the background by default. Background App Refresh can speed up app switching, but it depletes battery life and uses a small amount of mobile data.
Also, it may let some apps track your movements. Here’s how you can disable “Background App Refresh.”
Turn Off Background Refresh
To begin, go to your iPhone’s “Settings” app and select “General” from the “Settings” menu.
Then, tap “Background App Refresh” from the listed options. The “Background App Refresh” settings will appear next.
Note that you can remove Background App Refresh for specific apps if you want. To do this, tap the switch next to your preferred app.
Conversely, you can completely turn off the Background App refresh feature for all apps.
To do so, go to the top of the screen and tap “Background App Refresh.”
On the next screen, select “Off” from the drop-down menu.
NB: When you allow Low Power Mode on your iPhone, one of the functions that are disabled is Background App Refresh.
After turning off the background app refresh, your iPhone will consume less battery life in the passive state.
