iPhone 15 Pro Battery Life

So far my battery life has been horrible. I upgraded from 11 Pro to 15 Pro on launch day, and I swear my 11 Pro had better battery life. Yesterday, for example, I was at 55% with only 1 H 41 M of screen time (and that was mostly Reddit and email). I also noticed some apps like Next Door were running in the background for long periods of time (almost 2 hours), so I deleted it to see if it would make a difference.

How long should I let it settle in? I’m on 17.0.2, so hoping an update will fix this. I reached out to Apple Support last night, they ran a battery diagnostic, found no issues and had no explanation. They recommended I exchange the phone for another one.
