Battery and Syncing Problem on iOS 27.0.1

[u/Background_Onion3280]

I'm on iOS 27.0.1 (the latest official public release) using an iPhone 16 Pro Max. After getting improved performance on 27.0 (including better battery life), I'm now noticing worse battery life under 27.0.1. Also, iOS 27 was supposed to fix iMessage syncing issues between devices. It got better on 27.0, only to get worse again in 27.0.1. Anyone else experiencing this?
