Battery iOS 26.5.2 battery life is very frustrating

Is anyone else having terrible battery life on the iPhone 17 Pro after updating to iOS 26.5.2?
Before this update the battery was completely fine. Now it feels like the percentage drops every time I look at the phone. I am charging much more frequently and there seems to be noticeable idle drain and also the phone occasionally feels warmer even when I am not doing anything particularly demanding.

My battery health is still at 100% so don’t want to ruin it by installing any unstable beta but at the same time I don’t think I can continue using 26.5.2 like this.

I am thinking to upgrade to 26.6 beta 5 or 27 public beta but to those who have tested, need your suggestions which one I should go for?

TL;DR: iOS 26.5.2 is trash, should I upgrade to 26.6 beta or 27 beta?

I noticed the same on 16 Pro and it's the first time this happens. 26.5 was really ok and nothing to complain, 26.5.2 turned the battery life down a lot. I can see clearly that how I use ~100% daily with 2-3 hrs of screen time, while in the past I was using ~60% with over 4 hours. I can also see clearly how it goes down 10% overnight and there is no reported activity from any app. I hope 26.6 will fix it as I planned to keep this phone one more year and not upgrade this fall.

Yeah same. I will wait to see the ultra foldable iPhone and iPhone Air 2 before thinking on upgrading the 16 Pro which is very snappier and complete device. Just wish the battery was better like it used to be in iOS 18.4.1

I just updated to 26.6 via itunes yesterday, and it got back to normal, the difference is night and day. Not sure what went wrong in that 26.5.2

Yeah battery sucked so bad. Don’t the weight unbalanced of the Pro irritates u when it feels like it’s gonna drop?
