iPhone 14 Plus iOS 16.4 Battery Drain

Agree! My iPhone was draining fast with 16.4 update. 16.5 made it drain a bit faster. I’ve been on and off internet for the past 45 minutes and battery has drained 9%.

See post from Criptonomicon. I’m going to try that but with Apple Genius Bar assistance. I’m a bit technologically challenged. 😩

I restored my iPhone from the factory, 100% battery health I installed iOS 16.5. With 100% charge I left my iphone at midnight and went to sleep, when I woke up at 6am I had consumed 10% of the charge without any use! In iOS 16.3.1 in the same test he lost only 1%.

I was at the Apple Genius Bar this morning to reset my iPhone 8 Plus to factory settings. Did everything in the above scenario, using my phone (not computer), under the watchful eye of one of the techs there in case I screwed up. I did remember to back up to iCloud and turned off Find My Phone.

Only thing… iOS 16.5 didn’t need to be reinstalled because either the iCloud restore brought it over or the factory reset did. Everything restored as before, but…

Was at 80% battery when I returned home, used iPhone for 54 minutes and now battery is at 77%.

Is this normal? All I did was check a few emails and hop on internet…(?) 🫤

I’ll make another appointment! I tried the computer method over the phone, from home with Apple Support, 2 months ago (had to download/go thru iTunes??) but there no improvement. I was on 16.4 at the time. You’re still seeing improvement? That’s encouraging!🤞

Yes, the method I used involved iTunes and restoring the phone that way. Yep, still no complaints. I finished charging my phone at around 10:00 ET local time today. After about five hours, my battery had fallen by just 2%.

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!

Thanks. Yes, did all the above. No VPN, all background refresh turned off, charging phone 2-3 times a day, and bought a power pack. Been living this way since the end of March. If I do get a new iPhone… no iOS updates for me. (I can live without new emojis.) One final trip to the Genius Bar and then I surrender. 🏳️

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.

Just google for "battery health ios 16.4". Here, Apple will reply with different accounts telling you "some users have the weird notion that battery shouldn't degrade"... So we are weird for Apple!

Plus, not even Chinese phones degrade so quickly and so obviously after an update.

For me, the ghost touch in a undamaged screen, the dumb keyboard, the planned obsolescence for battery life and charge time have been enough. See you on another brand when this iPhone that was expensive and under spec'd dies.

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.

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.
