Battery life seems solid for me. iPhone XS Max, 100% battery health, fresh DFU mode install. Stays really cool and no overheating issues.

Getting about 7-8 hours SoT which is the same as when I bought the device in 2018, on its original iOS version.
Ah, yes. The DFU restore new really helped my iOS experience, too.

Must have been a bunch of gunk from over the years. It’s was great.

Thank you, yes I love doing the fresh install and start from scratch. It does make a huge difference. Going through the setting is a huge pain though. I’m trying to see if doing fresh install+either iCloud/iTunes restore would act the same way.
After my DFU restore I just tested having a vanilla iOS experience, and it didn’t really affect battery life at all to keep all the settings turned on.

(I think the only ones I turned off were locations settings for product improvement and maps, as well as turning all log sharing except for iOS with Apple: i.e. no sharing with health, AppStore, and app developers)

iOS 16 killing battery time for me. Apple Support told me wait for next update.
Debating whether to return iPhone after all Battery time is important to everyone

13 mini here. I got rid of the lock screen weather widget and my battery seems to be back to normal for the last few days. It was probably about 30% worse before I did that. It could be coincidence, or it could be that I updated to 16.02, I don’t know. However, battery life is back to iOS 15 performance now so I’m leaving the lock screen weather widgets off.

I have an iPhone 12 currently running iOS Version 16.0.2 (20A380). Since I upgraded the iOS from 15.6, battery life sucks. All the you gotta wait a few days and power off your phone hasn't worked. In addition to very poor battery life, now when I charge my phone with the screen on and/or an app open, the phone overheats and then I get the charging paused until your device cools down message. After a week and an update which didn't address battery performance, I'm very displeased with iOS 16. I'm ready to return to iOS 15.6.

OK, so I thought that I'd been doing OK with my 14 Pro after last weekend. A week of ending up with 20-30% left after a days normal usage. Even managed a 5 hour Strava ride on Saturday without too much impact. Hit the red zone that day,

However yesterday I ran out of charge going to a gig. Off the charger at 7:30. Plugged into CarPlay for 3x0.5 hour stints in the morning and the phone was just under 80% when I headed out the house at 4pm. 1 hour train journey listening to music and playing games, followed by an hour in the pub browsing the web and twitter. I didn't note battery at that point. Got to the venue at 6pm. Took approx. 90 photos and by 1045pm the phone had died and was in Power Reserve.

I switched the phone to 4G before I think it hit the red zone but that doesn't look like it's made a difference.

Yes this exactly what I wrote in another thread, remove all weather widgets on the Lock Screen for now, and see what it does to your battery life :)
Hopefully we’ll be able to use them again when they fix this abnormal use if battery for these widgets that are location dependent

I have never been one to notice/experience battery drain after an iOS update, but I definitely think it's happening after this one. I don't track my SO time, so I'm not sure if what I'm experiencing now (~4h 17m) is bad or not... but my battery is barely surviving the day now, whereas I always used to have around 20% left at bedtime (I'm on an 8 Plus with 97% battery health). Right now, I'm at 91% at 10am, with fairly light use since taking the phone off the charger at 7am.

Yes, I read your post and that’s why I got rid of the weather widget. It worked. Thank you!

2,5 hours screen on time and almost 3/4 of my battery drained. This is the worst battery life I had under iOS so far. I’m on an iPhone 14 Pro.

I think there's something going on with the 14. My 14 Pro Max battery life has been noticeably bad compared to my 13 Pro Max. I'm actually returning the 14 Pro Max and I've switched back to the 13 Pro Max, and despite the phone being a year old, the battery life is far better.

I'm guessing it's something to do with software, but I'll wait until I see Apple fix the issue before I commit to owning a 14 Pro Max.

The battery drain reminds me of one of those weeks in the iOS16 beta where battery drain got really bad. It feels exactly the same, actually, and Apple ended up fixing that. So I guess we'll see. Your move, Apple.

Having read this thread and now I'm noticing a slight downgrade in battery performance. I'm still OK but at the end of the day the percent is less than it used to be

I’m on iPhone 8 and have a new battery. It was lasting a full day before. Now even in sleep most of the time, I have to plug it when I arrive home after work.

I thought I was dodging this issue until today with my iPhone 14 Pro Max seeming to have about the same battery life as my 13 Pro Max (both on iOS 16.0.1). A bit disappointing since with the newer SoC and more efficient Qualcomm modem I was hoping for some improvement but at least not bad drain. I only charge every third day or so and my phone was not on the charger last night. I have automations set up to put it into low power mode and turn on airplane mode between 11:00pm and 8:30am so usually during the night it loses about 3% charge but last night it lost 20% doing absolutely nothing with the battery display not showing any rogue apps chewing up battery so either it is something in iOS or some rogue app is doing something, and iOS isn't even seeing it to report it in the battery use statistics.

Apple definitely has some work to do here. Losing 20% in 9.5 hours when the phone is in low power mode with all radios off and I also always have background refresh set to globally off is simply not acceptable.

I thought these issues only happen to older phones (mine for instance is 12ProMax) to force new purchase. I didn't know it would apply to 14ProMax.

Sadly not, and I've read reports from other 14 Pro users as well. Also, I always do a new set up for my new phones rather than restoring from a backup or transferring from my exiting phone so my battery drain can't be due to bad stuff accumulated from my old phone. Hopefully 16.1 will fix this. I'm only on 16.0.1 so I could upgrade to 16.0.2 but we're getting so close to 16.1 not that I think I'll just wait for that.

I noticed battery drain with iOS 16.0.2 on my 14 Pro Max as well. But I noticed that there is *something* starting/triggering it.

I can be fine for 1-2 days and get no battery drain, same screen on time like on my 13 Pro Max. Then, something happens, and from that moment on, it drains about 30% faster. And it will keep doing that, for days. Until I reboot the iPhone. Then it will be fine again for 1-2 days.

So far I wasn't able to identify what triggers it. And no, it's not any individual apps doing that, as in the battery statistics I see literally no activity at all that looks suspicious.

I do have a weather lock screen widget, so maybe it is a bug related to that which only shows up sometimes (and then gets stuck until I reboot). Let's see what iOS 16.1 brings.
