iPhone 15 Pro Battery Drain Issue

Well, I just updated to iOS 17.0.3 and my iPhone 15 Pro 512gb natural titanium is still as warm as ever and the battery has still dropped 15% in one hour …

I talked to someone who works for Apple and they said it’s not gonna get any better that they had better venting and heat dissipation for the 14 pro with the stainless steel and that the A17Pro Chip gets too hot …and titanium doesn’t allow it to disperse. I don’t think any software update is going to make this work. and when you have a hot chip, you’ll have a battery that drains extra fast.

Known problem with camera app. My battery drained too and after poking around found that it is the camera even if it is not used that is draining the battery. On my phone this problem only appeared on the fifth day.

according to Second tier tech-support Apple engineers are aware of this problem and working on a fix.

I have nothing much to add, but it’s the same problem to me. I transfered the data from my 13 Pro via iCloud Backup. On the fifth day of usage I can literally watch the battery counting down even though I use it little and in short periods. Yesterday the battery procentage dropped from 50 to 31 by just doing 15 mins of FaceTime.

Screen always on is switched off as well as unnecessary location services and 95 percent of all background updates in apps. The battery percentage is going down way faster than on my 13 Pro with battery status of 87 percent.

But what concerns me even more is that after the battery level going down to 31 it charged like a rocket.

It rushed from 31 to 51 after 15 mins of charging. From 51 to 83 in another 30 mins. So from 31 percent to 83 it took only 45 mins.

And in total it charged from 31 to 96 percent within 60 minutes.

I have talked to apple support on the phone 4 different times after taking my phone to an apple store prior to that. I had talked to 2 really nice women and finally, a really kind apple support agent said she would like to send me a replacement phone. My phone is up to date on the latest iOS. The battery continues to die extremely fast, I can get a full days use out of it only if screen time is about 4 hours.. the apple agent told me on a brand new pro max the battery should be lasting way longer than that DESPITE the logistics on the battery saying that the battery is totally perfect (background app refresh is off, and always on screen is off). She told me her husband has the exact same phone as me (256 GB storage and Natural Titanium color) and his lasts all day talking on the phone and screen time way higher. Not sure what happened in production.. why some phones are working and others are not doing well. The phone will get to me in a couple weeks and I will update again soon

Hello all,

Good news on my side after I would say 1 month and a half with terrible battery longevity,

I had every diagnostics with technical teams of apple did also a genius appointement that confirmed no hardware issue and now that times and new releasesn of ios are delivered, I have observed that the battery is greatly better now without any replacement (somehow an improvement to a normal durability)

hopes this helps

Well over a month now I have had my iPhone 15pro and today has been quite a busy one, made about a dozen calls, played some games for a couple of hours, tethered laptop, got like 50 text messages, web surfing and says 4hrs 58min screen time and it’s at 40%. Haven’t need to recharge. I always disable always on as well as the display will be the biggest drainer on the battery. Initially, yeah. No iPhone I’ve owned would last me a full day without going into the re <10%. You can’t compare a standard iPhone to a Plus or Max model either like some of the comments in this thread. Its no worse than my old 14pro and better than my 12mjni that I had before.

the phone itself is fine, battery is as good as any other previous iPhone so if you have a 14pro and thinking of upgrading I would say don’t bother and now my biggest hate is that all my family have older iPhones and I need a different cable which is a pain in the bum in the car. If you have issues I say reset to factory, test it for a week then complain.

Hi everybody after update iOS 17.3, it seems the battery problem solved but l am still testing it now everything goes well. l have been using the iphone for an hour and half, my battery is only %1 low now. testing goes well now.

As much as l observed, l detected the problem with battery. l wanted all my friends who bought iPhone 15 pro max to look at the production dates of the batteries.

I determined that all iPhones with battery production dates in OCTOBER 2023 have battery drain issue. But I see that there is no problem with iPhones whose battery production dates are in September.

PLEASE LOOK YOUR BATTERY PRODUCTION DATES :  (and writes your dates)

SETTINGS-GENERAL-ABOUT (at the end)

Since updated to iOS 17.3, my iPhone 15 Pro’s battery has been excellent. I charged it to 100% at 9 PM last night, and it's still 29% as of 3 PM after regular use (YouTube, Reddit, Podcasts, Maps, etc). It's been 18 hours and it's still going strong. This is just the first day after the update, but I hope my battery issue has finally been fixed.

i literally got my iphone 15 pro max 1 week ago. Had 13 pro max before. My usage pattern is the same. The new phone doesnt survive a whole day. Called apple support and they its not a commom problem and they ran a diagnostic saying everything is fine. Then they told me it might be a software issue, so i did a complete FRESH restart without my previous icloud backup. Same problem. APPLE FIX THIS PLEASE . We dish out so much money for their products and they get these problems. Im so surprised there are literally 3000 me toos on this issue smh

On Friday I reset network settings. Unfortunately I didn't any difference. Even my wifi connection wasn't lost as apple says. Anyway. Late evening on Saturday I performed "reset all settings". Still it is not a perfect solution because this time you lose connection to all wifi all settings and Apple Pay cards. Some features don't work until you turn it off and on again like auto fill passwords. Maybe it was another bug of ios17. Whole Sunday I was using my phone only on LTE (3 bars out of 4). Idle draining was satisfying. I think it gives me 5-5,5h SoT on LTE 3/4 bars. That's ok. Not perfect but could be worse. Yesterday I tried normal things. Mostly Wifi etc. but I left home for a while (1h) and immediately lost 2%. But first thing is Tesla. Second thing is that phone has to connect to the network. So every time it switches from Wifi to LTE/4G/5G whatever it takes a bit more energy. Moreover I spent 30 minutes in 1 bar lte area.

Interesting thing about mentioned Tesla. First time ever I can’t see this app in battery chart. Previously it took 2-3% every time I was getting into the car. Even though at the end of a day Tesla was way down on the list but I think it triggered some additional network connection which wasn’t counted as Tesla.

Anyway. It looks like “reset all settings” helped. How long will it last? No idea. Previously when I did clean instal few times I saw great results right after that and way worse results after few weeks. As I said before. Still reseting all settings is not a perfect solution. Especially if you want to that after every single update.

P.S. One more reflection. I am afraid every time I have to turn off and on my iPhone or restart it. Why? Because I think that every single time I do that battery behave differently. Sounds weird I know but that's what I think. Unfortunately last iOS version are too buggy to not doing it. Today I had to do this because...iPhone didn't want to charge via usb-c cable.

So the iPhone is relatively new so since you got it on the 9th of December it can take anywhere from 24 hours to a week to index itself

It appears the new 17.3 apple iOS download fixed message sync issues and battery life issues, I’ll give it a few days and report back

Hey guys! Got my iPhone 15 Pro also 3 days ago and very upset with the battery capacity.

fullu charged at 7am when I wake up and not using a lot the phone. Some WhatsApp’s for working , around 4-5 calls 1 -4’ a rasgue duration. Even closing apps to try extend the charge and it’s now 2:22pm and I have 28% charge only? Come on this is a premium smartphone. Something is not working and apple should refix this issue.

Any other place where we can claim to apple for a solution, 1300€ phone and the battery does not survive at least 1 day in a normal use?

I have the same issue. My iPhone 12 did not drain as fast as my new «flagship» iphone 15 pro. The drainage is crazy aprox 1% pr minute with or without the always on, on or off.

It should come i update/fix fast from Apple. This is crazy i havent experienced anything like this.
