We hope this helps.

Same thing but with my 14 pro max. After the iOS 17 update it would get hot during calls and also my battery drains a lot faster. Before ios17 i would talk all day while having my watch ultra and AirPod pros connected and when I get home from work around 9pm and i would still have 40% battery and now I’m at 20% by 4pm. I hope the next update actually fixes the issue. At 17.2 now and still no fix.

I upgraded from the iPhone 12 to the 15 Pro and the battery life on this phone has been rather disappointing, I have had it for a week and tried multiple things. Currently running IOS 17.02 on both phones and the battery on the 12 still seems solid even though its battery health is at 80%
