Thus, you can delete the normal photos to save space. Head for Photos app, delete them and permanently remove them from “Recently Deleted” album. If you don’t want to keep normal photos in future, you can proceed to Settings > Photos & Camera, and disable “Keep Normal Photo”. Next time, your iPhone will auto save only the HDR pictures when taking photos.

  • Remove deleted voicemail and Safari browsing history

Remove deleted voicemail permanently: go to Phone > Voicemail > Deleted Messages, and tap Clear All.

Clear Safari cookies and browsing history: proceed to Settings > Safari, and choose Clear History and Website Data.

4. Update your apps to the latest version

If you haven’t update iPhone apps for a long time, after installing iOS 11, the apps in old version may not be compatible with the latest iOS and slow down your device. To check whether there are apps waiting for update, go to App Store > Updates, and tape Update All.

5. Turn off unnecessary functions

  • Disable Background App Refresh: go to Settings > General > Background App Refresh > Disable it.
  • Turn on Reduce Motion: head for Settings app > General > Accessibility > Reduce Motion > Turn it on.
  • Enable Reduce Transparency: Settings > General > Accessibility > Reduce Transparency > Turn it on.
