Installed launch day and definitely worse. Today was the first time ever my 12 Max Pro died on me.

Hopefully it’s gets better.
 
All good here, 13 pro max, 66% left

I've also installed it on my 12 pro, standby drain seems ok, I'll post back after some day-to-day usage.
 
That's beast. Would you consider the battery life of 13PM to be better than 11PM was when it first came out in 2019?
ABSOLUTELY!!!

Hit 12 hours the other day with 16% remaining.

10 hours yesterday with 40% remaining.

Very much so. A couple of days ago I realized I hadn't charged my 13PM the previous night, so it started the day off well below 100%. I used the phone as usual all day, and at night before I went to bed it was at about 35%. I didn't charge it until mid morning the following day. I'm honestly surprised at how long the battery in the 13PM lasts compared with my old 11PM.

iPad Air 2 — dramatic decrease in battery life. Can drop 30-50% in just an hour or two of browsing. Much worse than before the update.

It's also been several days now, so any background updating should have happened by now. And, I abandoned Home Screen widgets. As usual, background app refresh, Bluetooth, and Location Services are OFF.

As long as they permitting users to upgrade to 14.8.1 and NOT go to iOS 15, they should let those of us who mistakenly upgraded roll back to 14.8.1. That would be only fair.

It's also blatantly unfair to permit that update only via over-the-air, but not offer it as an option when connected by USB cable and iTunes. I knew I needed to upgrade for security purposes but, had I been prompted with choice of 14.8.1 or 15.1, I would have chosen 14.8.1.
