- Battery is draining 2.2 times faster than before.
- Battery health was before the update 98%. It had dropped 2% in 2 years. Within 1 week after the update, battery health dropped from 98% to 96%.
I have read reports that battery drain has improved on iPhone 15. This makes me wonder is Apple trying to push the sales of newer models by killing the batteries of the older models. On the positive note, recent iOS updates have behaved better obeying settings and not forcing themself like in some earlier iOS versions.
Apple forums and iOS reddit are still heavily censored sweeping all update issues under the carpet making them waste of time.
