iPhone 14 Plus iOS 16.4 Battery Drain

Oof. It's very strange... Continue to chat with Apple support.

However, I have also noticed that my phone is draining battery even when it is not in use or in standby mode. I have disabled background app refresh and location services for apps that I don't use frequently, but the battery drain issue still persists.

Yes, it still persists because the phone is busy doing things that you can't turn off.

Do you have any other suggestions for resolving this issue, or is it possible that there may be a hardware problem with my device?

You need to wait. It is highly unlikely that there is something wrong with your phone.

Downloaded latest 16.4.1 this morning after 16.4 was driving me crazy with battery draining, ticking down almost 1% a minute. Genius Bar offered suggestions, none worked. Draining still but I notice at a slightly lower rate. Down 15% over the course of 3.5 hours, but not always in use (iPhone 8 Plus). My phone was fine until 16.4. Where can I contact Apple to officially complain?? This is inexcusable.

I updated my iPhone 12 and my husband’s SE on the same day. I’ve notice my battery drains faster than normal but nowhere as quickly as my husband’s battery. He may use his phone a couple times a week, which meant he only had to charge it once or twice a week. Since he updated to 16.4.1, his battery drains to 1% in less than 24 hours without him using it all. I hate to see how quickly it drains when he does use it. Hopefully Apple has a fix to this issue very soon.

I was in touch with Apple Support about this issue, after several gyrations and recommendations by the Genius Bar. My battery is brand new so the issue has to be the software or the phone itself(?). iPhone 8 Plus worked great until 16.4. Anyway, my complaint was taken by a senior technician who escalated it to the “Engineering Team”. I had to provide screenshots of my battery usage (% and minutes) for past 24 hours and past 10 days. I’m supposed to get a call back tomorrow morning with any findings. Will let everyone know. Very frustrating! 😩

Yes all were restored… except text messages… including the battery drain problem! ☹️ Email had to be re-set up, non-Apple apps re-downloaded. Third time I had to do this. Finally got the email “link” for Apple about this issue, but it’s the same email form as usual: http://apple.com/feedback

At least this time I can add a couple of case numbers. 🤷‍♀️ Frustrating, futile day…

in response to all

I do know this…

Y’all got super strange iPhones, my battery’s doin’ great on my 14 Pro… screen was on playing music all the time I was at the gym.

what I found is that I get better battery life if I reduce the frequency of mail fetch and turn off most of the apps that do background app refresh.

you don’t have to be on your phone to use battery… YOUR PHONE IS ON ALL THE TIME, and therefore must use battery life… so reduce the amount of background activity… like not leaving a bunch of apps in the background when you go to the Home Screen 🤣

hope this helps

May The Lord bless you and keep you all!

I just upgrade to 16.4.1 and its draining super fast on iphone 12 Pro, it terrible how fast it was 80 and in 20 minutes its already 66 is illogical !! I hate when the do thing wrong. Hope they fix it since we spend a lot ok money on their devices. They should not force phones to drain battery to try someone to purchase new phone or battery

I updated to 16.4.1 at least four days ago, since then I've been monitoring this extreme battery drain through Battery settings; overnight last night it dropped 29%, and when I select individual hours to find out what's using the battery, I see Screen Time On 0m, Screen Time Off 0m, Usage by app is not available for 4AM - 5AM (for example). Drop is very consistent across the overnight hours though - it's a very steady downward slope on the battery graph.

I'm using an iPhone 12 mini w/battery health at 96%. Battery would consistently last almost 48h prior to 16.4 / 16.4.1 - it was great! - now I don't make it to 24h, even with minimal use. Phone is also consistently warmer than usual, even when not charging and w/cool ambient temperatures, so it must be doing something in the background, even overnight, but I guess whatever it's doing is a hidden system process that don't get reported to the Battery settings? I would figure after four-plus days, that any iOS "indexing" would have been completed.

Please post this comment to Apple in their Feedback link, as well! You are lucky you didn’t upgrade to iOS 16.4 on your older phone. Going forward, I won’t upgrade unless it’s absolutely vital for national security! 😡

I downloaded 16.4.1(a) as well. Battery drain continues as fast as when I downloaded 16.4. Also charging twice a day. Time for another complaint on Apple’s Feedback site. I encourage everyone to do the same!

I’ve read all 9 pages of comments. This battery drain is no “small” problem. My new battery drained 27% in less than a half an hour. Three days ago before this 16.4.1 update my battery lasted all day unless I was using it heavily then I’d have to charge it a little at the end of the day. I’ve tried every offered suggestion I’ve found online and here to no avail. I switched from Windows and Android because I thought Apple was better than this. Being tethered to a charger 24 hours a day is simply not an option. I sure would hate to go back to Windows and Android but this is unacceptable. By the by, my battery went down 3% in the amount of time it took to type this and typing is my job so you can guess I’m not a slow typist. And so begins my disenchantment with Apple. So sad

It’s terrible. I’ve never experienced this in the 5 years I’ve updated my iPhone 8 Plus with the latest iOS. I’ll say it again, please complain on the Apple Feedback site. If enough of us do, then maybe… ?

Your husband's SE is just like my iPhone 8. One week after updating to 16.4.1 and closing down almost everything including emails, the battery on my iPhone 8 is at a stable draining speed of 7% per hour, even at standby or shutdown, on airplane mode or low battery mode.

Before the update, I charged the battery by 40% everyday, roughly from 40%~80%, which means a 1 cycle in 2.5 days. Now I have to charge the battery by 50% 3 times a day, from 40%~90%, which means 1.5 cycles each day. Before the update, the battery health is 90% after 3.5 years usage, now it's 89%.

I hope the honorable Apple developers find the above info useful and give us a solution soon. Thanks all for the input.
