    It will turn green. [1] Doing so can improve your iPhone's battery usage by as much as 40 percent. [2]
    • You can also tell Siri to "Turn on Low Power Mode."
    • When your iPhone's battery charges to a level above 80 percent, Low Power Mode automatically turns off. [3] Turn it on after charging to save battery power.
    • Using Low Power Mode affects several of your iPhone's features:
      • Email will not fetch as frequently.
      • The Hey Siri feature, which allows you to activate Siri without holding the Home button, will not function.
      • Apps will not refresh until you launch them.
      • Auto-Lock will default to 30 seconds.
      • Some visual effects will be disabled. [4]

    Expert Answer
    Double-click your home button if your device has one, then swipe up on each app. If you don't have a home button, use your finger to swipe up from the bottom, similar to how you swipe up to minimize an app. However, when you swipe up, don't release, but keep your finger on the display until the menu pops up revealing all your background apps. From there, you may swipe up on each app to close it.
