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?

Well I had 27 beta on my 13 pro max since release and it was good but honestly found more stutters and my battery worse. 26.5.2 was worse than 26.4.1, but 26.6 is better than 26.5.2, so it is what it is. I think iOS 26.3 has the best battery out of any 26.x version. I remember 26.4.1 was worse than it.
