iOS 27 Battery Life tested on a daily driver iPhone | iOS 27 Battery Drain reviewed after updating 15 unique iPhone models to iOS 27! With iOS 27 Beta 1 we know Apple has promised 30% faster performance, but there were also rumours that the battery drain issue in iOS 26 would be fixed as well. These are not just rumours in iOS 27. The battery life is so much better on iOS 27 on my personal iPhone 15 Pro Max than it was on iOS 26.5! Moreover, all of the 15 iPhone models I updated to iOS 27, including iPhone 11, iPhone 12, iPhone 13, iPhone 14, iPhone 15, iPhone 16, iPhone 17 (I updated at least 1 device of each major iPhone model including Pro's, Pro Max, Plus, Mini), and not a single one of them had excessive battery drain after freshly updating to iOS 27. I showcase the older iOS developer beta 1's and just how much worse they were compared to iOS 27! I hope you enjoy.
