Noticed the same thing on my phone.

All my devices (iPhone 11, iPhone X, iPhone 6S and iPad Pro 1st Gen) are updated to 13.4. No issue at all.

I have no such issue. On 11 pro max.

So far still ok although my battery health is at 85% only now. No noticeable battery life difference compared to before ios 16. Can last for 8-10 hrs with typical usage in the office without charging
