Turn Off Background App Refresh

Background App Refresh allows apps to refresh their content and data in the background when you’re not actively using them. It’s convenient, but also taxing on your battery.

Try turning off Background App Refresh for apps you don’t need updating constantly in the background:

  1. Go to Settings > General > Background App Refresh.
  2. Switch Background App Refresh to “Off” or toggle it off for individual apps.

This prevents apps from sapping your battery in the background when you’re not using them. You can always turn Background App Refresh back on for essential apps later.

Disable Location Services for Unnecessary Apps

Location services allow apps to pinpoint your geographic location. While useful, it can drain your battery as your iPhone continually pings cell towers and GPS satellites.

Evaluate which apps truly require location access and disable it for apps that don’t:

  1. Go to Settings > Privacy > Location Services.
  2. Review the list of apps using your location.
  3. Tap on each app and select “Never” to disable location access.

Restrict location access only to apps that truly need it, like Maps or ridesharing services. This will lighten the battery load without sacrificing essential functions.

Reduce Screen Brightness

The brightness level of your screen significantly impacts battery life. The brighter the screen, the more battery power it consumes.

Try lowering your screen brightness to extend battery life:

  1. Open Control Center by swiping down from the top right of the screen.
  2. Drag the brightness slider to the left to reduce the brightness level.

You may need to adjust your eyes, but lowering the brightness makes a big difference in battery conservation. Auto-Brightness can also automatically optimize the screen based on ambient lighting conditions.

Enable Low Power Mode

Low Power Mode is an iPhone feature that temporarily reduces background activity to preserve battery life. It disables or limits mail fetch, background app refresh, automatic downloads, and some visual effects.

Enable Low Power Mode to stretch out your battery:

  1. Open Settings > Battery > Low Power Mode.
  2. Toggle on Low Power Mode.

Your iPhone will now optimize performance and reduce power usage until you turn Low Power Mode off. Use this when your battery level gets critically low.

If you’re still experiencing battery drain after trying the other steps, resetting all settings may help resolve software-related issues.

Here’s how to reset your iPhone:
