iPhone 14 Plus iOS 16.4 Battery Drain

Hello, I just received my iPhone 14 yesterday, and it came with iOS 16.3. I downloaded 16.4.1, but I'm afraid to install it, will it drain my battery ? Isn't it better to wait for my battery to calibrate for two or three days, before immediately updating to 16.4.1 ? Thanks !

I recommend using a little in iOS 16.3 in time to be able to have a battery autonomy parament when migrating to iOS 16.4.1 just like this for you to be able to compare and see if you are consuming more battery or not.

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.😫

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.

Going forward, make sure you have iCloud Sync for Messages enabled.

Once you log back into you Apple ID on your device (iPad, iPhone, Mac), the messages will re-populate.

Here is a photo of my husband’s IPhone SE. it’s been sitting on the table and the battery has drained 20% in 3 1/2 hours. And you can see no apps are running. It will be completely dead by morning. This is completely unacceptable.

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…

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??

I’m also feeling the battery drain as soon as I updated my XS Max to 16.4.1. Unfortunately, this 16.4.1 version is the only software version that is signed, no more going back to 16.3.

Thank you.

Ever since battery drain with 16.4, I’ve been hoping for subsequent updates to help this issue. I was told by an Apple specialist that updates are rarely only for security, even if all other “fixes” aren’t specifically noted.🤷‍♀️

Ah. Then it was my wishful thinking, based on what the Apple Specialist told me (we were on remote view of my iPhone and the specialist was astounded at how quickly the battery was draining). I wish Apple, as a company, would address this issue. It seems so random yet affects 100s of us. 🙁

The Rapid Security Response updates are very new. The first one was released earlier this week. So, at the time you were told that updates were not generally security only, it was probably accurate.

If it is "hundreds" of people affected, that's still a miniscule percent of all iPhone users, even of all iPhone users of iOS 16.x. That makes it very, very hard to gather enough data to figure out what the problem is. And, to be brutally honest, if I were in charge of such things at Apple, a problem that affects a very small number of people and may or may not be caused by iOS would be way down my priority list.
