iPhone 14 Plus iOS 16.4 Battery Drain

I had the same issue with my IPhone 14 plus that I bought 3 weeks ago. After updating I noticed the same battery drain and I didn't find any fix until I saw some guy on reddit that said that he fixed the problem by trying his IPhone without sim, it fixed it for him so he changed his carrier/operator so new sim. I tried mine without sim and it fixed the problem. Also I tried some other stuff that you see on videos like background app refresh and stuff.

If your phone is fine with iOS 16.3, I’d leave it be! I won’t ever download an iOS update again, is my feeling at the ... at least not until several months have passed and the all clear’s been sounded.😫

This seems to be a widespread problem. I saw an article

about it in Cult Of Mac the other day.

No answers from Apple so far.

One suggestion; If you're using

a VPN like Nord or SurfShark, turn it

completely off, as in zero protection and the app closed

and then watch your

battery usage. VPNs continue doing

something in the background even when

the phone is off (locked, not powered down)

The VPN guys will tell you that it's negligible,

but don't buy it. Look at your Battery

setting where it shows usage by app. VPN's

are often right up there at the top.

Or your passwords and other confidential documents 😂

I’m just saying: I don’t usually trust any old bozo who says they’ve got a “signed version of iOS 16.3.1” on their website

I get ALL of my OS’s from their respective websites only

the only third party place I would trust is archive.com to get WIN XP

Did your iphone 13 come to you with 16.4 or earlier ? I've had my iPhone 14 for two days, running 16.3, and the battery life isn't great (the battery isn't calibrated yet, maybe ?) ; so I'm a bit afraid to update to 16.4.1.

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! 😩

My screenshots and battery info/ diagnostics were sent to the Engineering team 2 days ago and seems the results came in same day(?). My scheduled call with the Apple Support specialist was to be today (2 days later) at 9am or a little later. By 9:40am no call, so I opened another chat with Apple Support. Case went to a different support specialist who Said the engineers found nothing unusual (?) and that my average battery usage was lasting 12 hours. I wish!! This specialist said let’s try something else…walked me through transferring / restoring my data from iPhone via iTunes on laptop. I never use iTunes so it was a 1/2 hour process.

Upshot…

…my phone was restored as new(?). Only difference from previous resets and restores… my texts are now gone forever. Had to reset mail. Contacts, photos, calendar, and Apple apps returned. I had to redo all settings, reinstall some apps… and battery still draining!

I Opened another chat and this specialist did a remote share of my iPhone screen and agreed the battery is draining too quickly. She said she would send me a link to document this ongoing issue. I haven’t received it yet. She also said there’s nothing more Apple can do.

Hopefully there will be a new iOS update to address this. 😩

So … I’m emailing myself my photos and contacts. I will never do a restore from this phone again. I’ll hang onto it to keep my calendars.

If there’s anyone here who knows where a low-tech senior citizen like me can learn how to do this more efficiently, I’d love to hear from you. Very frustrating.

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 have mail to fetch manually and all background app refresh turned off. 16.4 throttled the battery’s ability to hold a charge. 16.4.1 was no improvement. Apple support specialist on remote screen share was surprised to see how rapidly the battery % ticked down during our 10 minute call.

I have a 12 Pro Max and there is no always on setting. I have the same issue, battery on 16.4.1 does not last. It seems that this happens a lot after an update and not just for a couple of days. This issue seems to be worse than the last battery drain after an update. I usually upgrade phones every other model. I didn't this year as I have a sneaking suspicion that the lightning port is going away. I'm betting that iPhone 15 will use usb C. The EU mandated that all phones must be usb C. I doubt Apple will have lightning for US and USB C for Europe.

I don’t think I’ll ever do an update ever again once my phone is 3 years old and it’s working well!

Update: was on the phone again with Apple last weekend and upshot is, they’re stumped why the battery drain issue and “hopefully it will be rectified with future updates”. 🫤

I plan to continue to email Apple and complain…

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

My ip12 was updated to 16.4 over 3 weeks ago and the battery no longer lasts an entire day even when it is not heavily used. Bummer. Apple needs to fix this problem or give instructions for going back to an older update.

Couple of days back i have updated the version 16.4.1 and just realized that it drain the battery life significantly. Any idea why it has this issue??

i beleive there will be an update soon? Isnt it??
