If you thought there is something wrong with your iPhone and short battery life, don’t worry it is just the latest iOS update. While the latest iOS 10.1.1 update brings “stability improvements and bug fixes,” according to multiple user reports, it also brings a new battery bug.
Some users have also reported that rolling back to iOS 10.1 didn’t fix the problem and that their iPhone 6 and iPhone 5S devices are still unable to last a full day without charging, and some iPhones are unexpectedly dying with “30 to 50% charge left.”
