iOS 17.1.2 iPhone 15 Pro Max massive battery drain issue

I have an iPhone 13 Pro Max and recently updated to IOS 17.1.2 and now my battery drains massively. I went to bed last night, checked my battery, it was at 30%. Woke up late this morning as alarm didn’t go off, phone was dead!

same thing with me , my new 15 pm would give me 24 to 26 hours of battery time , now it barely lasts 18 hours .

I get tired of hearing all the same Attempts to resolve the battery drain issue. Non of them really work. Using Change management process. You know that the issue was not present prior to the change ie. IOS Update. There for a problem was introduced with the change. The solution is to either roll back the software or fix the issue before reintroducing an upgrade. Enough said.

My new iPhone 15 Pro (using it since ~3 weeks) drops 2-3% every 15-20 Minute of use. This happened after the iOS 17.1.2 Update. This is not a „Pro Battery for all day“ like Apple says. It can’t be like every time I check the right top corner I see the percentage dropped again by simple activities like a few minutes YouTube, WhatsApp, E-Mail and so on. Really frustrating! When I get a „Pro“ smartphone, I don’t want to restrict myself to get over a day!

Hi, I have same issue since purchase new iphone 15 pro max. I already do every safe battery mode, turn off background, dark mode, etc. but still face same issue. My phone only can survive 20 hours without do anything in setting always display on “off”. Drain 1 percent every 5 mins do video call in whatsapp or open youtube video. I didn’t move only data yet from my old phone, only whatsapp but I download some apps already. I worry to continue use this phone.

Same problem as well to me just updated my 15 pro max and the battery drain so fast please fix this problem on next update from ios 17.1 till now the same issue 15 pro max users facing same problem

When you go to sleep (don’t use your phone for more than 5-6 hours) it literally drains up to 10% battery life, I don’t know if you’d the same issue.

My guess is that the main issue is a software one.

Yeh me too dude I almost regret it for doing this upgrade

I am not usually one to complain about battery issues online, but the latest iOS update 17.1.2 have seriously affected the battery life on my brand new iPhone 15 Pro Max!

Help

According to Apple:

After a software update is installed for iOS, iPadOS, tvOS, and watchOS, it cannot be downgraded to the previous version.

I own iPhone 15 Pro and 15 Pro Max, neither of which is experiencing any battery life issues at all.

How many of you who are suggesting less battery life, Force Restarted your iPhone after you do an iOS update? Likely none of you have and it is something I do after EVERY iOS update and after all these years, I have never experienced battery drain issues from an iOS update. EVER.

Follow the directions here --> Force restart iPhone - Apple Support

I update at one of and update. Just since checking

email and then posting this reply dropped now to 78%. So more to this issue. Only thing I’ve not done is a reset or a total wipe.

I have a 10R never had any issues with other iOS updates. Had a new battery put in. Was at 100% health and iOS 17 came out. After iOS 17.1 battery health fell to 97% where it’s at now.

Ok, so let’s clarify some things.

I use my phones alarm feature to wake me up in the morning. When I go to bed I put the phone into do not disturb and I close the screen. I always check the charge status prior to doing this, now, I have before now gone to bed with less than 10% charge and the phone has retained its charge (IOS 16), and woke me up in the morning. So yes, the fact the phone died at 30% since I updated to the latest IOS is obviously an IOS issue!
