What Features Does Low Power Mode Disables on iPhone or iPad?

Here are the features that are temporarily disabled when you turn on the Low Power Mode on your iPhone or iPad.

Email Fetching

If you use the stock Mail app, then your iOS device regularly fetches email and checks your email accounts to see if there are new mail messages. Your iOS device also checks for other types of data linked to your mail accounts such as calendar, notes, contacts and reminders.

Since iOS devices fetch for emails and other data periodically on a regular basis, this uses significant amount of battery power.

When you turn on the Low Power Mode on your iPhone or iPad, the email fetching feature of your iOS device is turned off. You can still refresh your inboxes manually by opening the Mail app and pulling down to refresh, however automatic fetching is disabled.

Background App Refresh

In addition to Email Fetching, iOS also performs other functions in the background, which includes background refresh. Both stock and third-party apps connect to the Internet and download new data in the background. This is done to save time and show user updated information as they launch the app.

Background App Refreshing uses significant battery resources, so iOS disables this feature when the Low Power Mode is activated in order to save battery.

When you turn on Low Power Mode or LPM on your device, iOS temporarily pauses iCloud Photos Sync. The syncing is resumed as the Low Power Mode is disabled again.
