Does anyone have absolutely terrible battery life on their iphone after the 16.4 update?

I have a 13 Pro and wow is it far worse than before... no idea what happened.

Just means a new phone is coming in September, but I agree

My iPhone X's battery went dead in a few hours after the 16.4 update ran, but has since been back to normal. Some iOS updates require a major rearranging or cleanup of the flash RAM when they first install, which can chew up battery power until it completes.

FWIW, 16.4.1(a) has installed on both of my iPhones with no visible hits on battery life.....

No issues on my 14 Pro Max and none noted from the better half on her 12 Pro Max.

My iPhone X's battery went through a similar depletion like yours. It was truly incredible how awful it was, and this is after I replace the battery at the Apple Store several months before. As of today, the battery seems much better, so perhaps the rearranging did its thing.

No issues on my 14pm or my kid’s 2020se.

[2000cs]

16.4.1 on my 12 with no issues, but I do a hard reset every few days because it seems to get tangled up internally, especially the cellular connection if I move between cells or fly a lot.

Same on the iPad (Pro 4th gen). Some apps seem to tie it up and performance always improves after a hard reset.

Both devices are 2020 so should be good for several more years. hahaha.

I don’t think it has sold as well as previous phones so maybe they are now doing the hard sell. Not a bad phone but I haven’t seen a reason to upgrade my 12Pro Max, and I’m an Apple fanboy kinda sorta. When the phones are over $1k you want your monies’ worth out of it. I realize they are more than happy to put you on the monthly payment treadmill and let you trade your phone in every year, but at least give me something more compelling.

Batteries on my phones do seem to be dying faster. Haven’t noticed as much on my iPad. My wife has really noticed on her phone but keeps hers in a case and I suspect it draws more power for a signal in the case.
