After installing iOS 7.1.1 when it became available on Tuesday, I thought I saw a marked improvement in my iPhone’s battery life. I’m not the only one as ZDNet’s Adrian Kingsley-Hughes noted the same on Thursday, sharing results from multiple six-hour battery tests. Prior to the update, his iPhone battery would drop from 100 percent capacity down to 48 percent. After installing iOS 7.1.1, his iPhone battery is only falling to 76 percent from a full charge in a test cycle. Several commenters on his article agree or have seen similar results, so if you haven’t updated to iOS 7.1.1, I recommend doing so sooner rather than later.
