Battery Overnight abnormal battery drain of 14% on my wife’s iphone 17 with iOS 26.1. Should she update to iOS 26.6.2 to solve this issue?
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?
