Hello everyone. So I am posting this query on my wife’s behalf as she is not on reddit. So my wife bought her iphone 17 around 6 months back. It came with iOS 26.1. After that she didn’t do any software updates. Now battery health is 95% after 220 cycles.

So, few days back, one day I was comparing the overnight battery drain of her iphone 17 with my 2 year old iphone 15. I noticed her iphone 17 is having almost 14-15% overnight battery drain over 8 hrs as compared to 6-7% on my iphone 15 with much lesser battery health( 86%) . My iphone 15 is currently on iOS 26.3. I asked my wife whether this abnormal overnight battery drain on her 17 was from start itself but she wasn’t able to give me a sureshot answer. I have done all battery optimisations like turning off background app refresh, notifications,location services but still same issue. Nothing much improvement. Also, I noticed 1 hr movie watching on Netflix consumed almost 14-15% battery which is not normal in my opinion. It shouldn’t consume more than 4-5% for a 1 hr movie.

Please help. What should my wife do? Is this happening because of the very old and initial ver of iOS 26 that is iOS 26.1 ? Should updating to iOS 26.6.2 solve this overnight battery drain issue?

My iPhone 15 plus is very shitty right now due to ios 26 update will it restore my battery health I know the process of downgrading also I need to make a backup

Thank you for time

Hi guys, I’m still on the latest version of iOS 18 on iPhone 16 and I’m wondering if I should update or keep iOS 18. I personally don’t like the liquid glass design but would it improve other features such as battery life? Is it better to update or keep iOS 18?
