What’s New in iOS 11.4.1

Battery Health and Performance Controls

Apple admitted to slowing down older iPhones so that the phone didn't suddenly shut down on newer version of iOS. Since then they've rolled out a batter replacement and promised better visibility to your iPhone battery health as well as controls.

With the iOS 11.3 update users can check battery health in Settings -> Battery on the iPhone 6 and later. Users can also see if Apple is using power management to prevent unexpected shutdowns on the iPhone 6, iPhone 6 Plus, iPhone SE, iPhone 6s, iPhone 6s Plus, iPhone 7 and iPhone 7 Plus.

When the update arrives, users can go to Settings -> Battery to turn power management off if they want better performance at the risk of shutdowns. Expect more on how this works when the beta arrives.
