iPhone 14 Plus iOS 16.4 Battery Drain

I recently purchased an iPhone 14 Plus and updated it to iOS 16.4. However, since the update, I have noticed a significant decrease in battery life. My phone is draining its battery much faster than before, even when I am not actively using it.

I have tried restarting my iPhone and checking the battery usage stats to see which apps are consuming the most power. I have also disabled background app refresh and location services for apps that I don't use frequently. Unfortunately, these steps have not resolved the issue.

I am reaching out to the Apple community section for assistance in resolving this problem. Has anyone else experienced similar battery drain issues after updating to iOS 16.4? If so, have you found any solutions or workarounds? Apple should take necessary actions. why a trustable company do like this to its customers?

You might be very disappointed if you move into the Android world.

Granted, they probably don’t have the battery problem that we’re experiencing, but you’ll soon miss Apple’s elegance.

Welcome to the world of tech. We’ve been through this kind of frustration before. Nothing happens quickly. Just keep charging, do all the due diligence stuff; shut down the extras and unnecessary background activities. If you use a VPN, shut it off. Some of them use tons of background battery. Buy a couple of power banks and keep them with you. It’s a good practice in any case.

Hang in there!

Epilogue. No change after trip to Genius Bar and resetting as new/restoring with Mac. No more can be done. Tech said (like previous one did) the newer iOS versions can do so much more, older iPhones have to work harder to keep up. Lesson learned. No more premium gas in my old “cars”. Stick with regular. Good luck, everyone. Good some of you got better results.

ok so i upgraded to the latest ios and it kinda helped with the battery drain. my 14pro now lasts as long as my 11 (with ios 15.7). Both devices get roughly the same use and both are always connected to the wifi and data.


im glad the ios update helped me (might not fix others’ battery issues) because i was literally looking at the s23 ultra the other day and it was looking mighty attractive at the store.

Hello everyone,


I wanted to provide a quick update about my experience, as there have been a few developments since I last posted.


As I stated previously, restoring to factory default settings helped me to restore my battery's drain time prior to iOS 16.4. My phone worked brilliantly...for a time. But with the release of iOS 16.5, iOS 16.5.1, and iOS 16.5.1 (c), my battery quickly degraded in performance. Which brings me to yesterday. I decided to restore to factory default settings again and restore from backup again. And once again, the battery's performance is working as it did before iOS 16.4.


I called Apple to explain what had happened across these two factory resets. They directed me to bring it into an Apple store. I did that this morning. They ran some diagnostics and found nothing wrong with the battery. (It's at 97% maximum capacity at the moment.) They said they wouldn't recommend getting a battery replacement, and they thought the issue might have to do with the OS updates.


I just got off the phone with Apple again to explain what happened during my appointment. They didn't provide much in the way of help. They said that I could send the phone to Apple directly, but I don't see the need to get back the same answer as I did this morning with an even longer turnaround time. They didn't say anything about the OS updates when I brought it up during my call.


Even so, it seems to me at this point that there's something off in the iOS 16 updates or in the update mechanism itself. I've seen some promising posts about the iOS 16.6 beta, and then there's always iOS 17 in September, so maybe one of those updates will fix it.


Resetting your phone to factory default settings will restore battery capacity for a while. I'm also thinking about trying this advice here so that I don't have to keep resetting my phone: https://discussions.apple.com/thread/254371223?answerId=258230131022#258230131022.


I was hoping for more promising news. Maybe we'll all get it in the next few weeks.

What are the model numbers of the problem phones here? What are the serial numbers? The factory that made the phones in question could have had a problem in the production line causing short-circuiting to occur in power circuitry, which would lead to abnormal draining of the battery and excess heat— hint: that would be a good reason the iPhone 11s, 12s, and 13s don’t have this problem that we know of, and if any, we don’t hear about it as often as we hear of 14 problems. 


A factory production line issue would also be a very good reason the Genius Bar etc. doesn’t know and can’t fix the problem. 


In that case the blame might be on the factory head honchos, not necessarily on Apple. If enough people tell Apple that a factory is producing bad phones, then Apple might investigate. We already know they don’t intend to produce bad phones, however, some factory higher-ups are careless.


That’s why looking at our serial or model numbers isa good idea because that would tell us factory and date.

My iPhone 14 pro model and serial numbers (I hope this doesn’t violate rules) model:MQ0N3LL/A serial:C2****R9V

Mine does not have a battery drain problem.


This is an opportunity to make Apple better not to abandon them.
