If you’re like most people, you probably turn off power saving mode on your iPhone when it’s not in use. But what if you don’t know how to turn it on? Here’s how:

  1. Open the Settings app and tap on the General tab.
  2. Scroll down and find the Power Saving section.
  3. Toggle on the power saving mode under “Turn On.”
  4. If you have an iPhone 6 or later, you can also toggle on “Do Not Wake” under “Sleep/Wake.”
