iPhone 16 Pro Max iPhone 16 Pro Max battery life [MERGED]

[Gcerdan]

Good afternoon. I have an iPhone 16 pro Max with iOS 18.0.1. I began to notice that my battery life was terrible. Going down 1% every minute during a phone call. I have updated the phone as a new device and the problem remains the same or worse, now every time I take a picture the battery goes down 1% with each photo! I've modified all possible settings to improve battery life and it's still a disaster! Any recommendation? I still have time to return the phone...

Chargerd to 90%. 28 Hours later at 20%. 5 hours total screentime (and 6 hours of sleeping connected to AW). Not sure how good this is, I feel like it should be better (1 hour screentime = 5% - 10% battery)

Wow, you literally only used it from time to time from 15-20 min each hour. And 4 hour is truly pathetic

Last charged to 57%? But it’s showing 100% that’s when it was the actual last charged timing ? What a glitch. Return your phone and exchange if possible

My 16PM battery is really all over the place. I tend to use my phone the same amount of time most days. I tend to wake up in the morning with it being on 100% at 7am. Sometimes by say 3pm, it’s on 70+ % still, other times it can be down to 40% without any changes in settings etc.

18.3b1 has resolved this issue for me. Hopefully it stays that way. First time since owning the 16PM that I haven't had to charge it in 24 hours. 14 hours since my last charge, and battery has gone from 80% to 49%. Could be a little better, but magnitudes better than before (There were some morning I would take my phone off the charger at 80%, and within 5-10 minutes I would lose 2-3% when doing virtually nothing).
