Battery Draining on my iPhone after recent iOS update

Same here since yesterday when I updated on 17.4.1, I have an iPhone 15 Pro (bought new at Apple Store when released last year), I startet this morning with 80% battery, typical low sunday-use (bit of music, insta and safari for in total 2,5 hours, no photos, no videos, no youtube, no calls) and 12 hours later my battery is at 19% ?!

Hope they’ll fix that soon!

Wow, I’m having the same issue. Updated to 17.4.1 yesterday. iPhone 13 Pro Max, battery health at 89%.

Force restart a few times. Reset of phone. Battery is 100%-33% in about 3-4 hours. I’ve never had this issue before. Consistently I can go almost the whole day before I need to recharge. And never have I gone down this fast.

I had the same issue with my AWU on one of the updates, and it was another update release that resolved the issue. I may get on the Reddit pages to see what they say. But this has been pretty quiet on what the issue is with 17.4.1.

i’ve got a iPhone 11 Pro and before the update 17.4.1 battery was ok, i toke about 7h 30 of screen with a single charge, my BH is 93%. now without doing nothing with my iphone using it about 1h30 today i have already dropped 75%, this is crazy bad. hope they’ll solve that with 17.4.2 or 17.5

Same here. It’s brand new Iphone 15 pro max, with 100% BH. Battery drains much faster after update and I noticed that Facebook app drains battery in background even if the app refresh in background option is off.

Same. I have the 15 pro Max with 151 cycle count and 100% battery health first used on October 6, 2023. After the 17.4.1 I can manage only 5 hours and 30 mins of screen on time compared to other iOS version with 8-10H of sot and I noticed there's a huge battery drain on standby mode. Apple should address this problem ASAP

Same problem here with my 11 Pro Max.

I’m a light user so before the update (on 17.4), I was getting to the end of the day with around 45–50% charge remaining. Now I’m having to recharge by around 4 or 5pm. I’ve tried force restarting and resetting but it makes no difference.

I usually hold back with iOS updates for this very reason but dropped my guard, thinking it was just a x.x.1 update. More fool me.

I have iphone 15 plus and after updating to ios 17.4.1 the battery life is significantly less. Before the update I was getting SOT of 7-7.5 hours, now the phone is struggling to give 4 hours SOT, Apple needs to fix this battery drain issue asap with a new update.

I have tried changing different settings including 'Background App Refresh', 'Location Services', 'Tracking' and a few more. 

Battery life is still miserable with 17.4.1 as compared with 16 for my iPhone 13 Pro.

'Optimized Battery Charging' also does not work as expected since a few days, although I am connecting and disconnecting the device almost at the same time every day.

My understanding is that iOS 17.4.1 is defective. It's a pity because the 13 Pro used to be a very nice device.

So while updating via mac there was a firmware (i.e. modem update), from my time working with custom ROMs @ android I learned that having a mismatched driver with an OS version is a severe drain…

let’s see how it goes now, but could be that apple messed up the ota firmware update and that this is the cause of the issues. Will update

Did my update this morning iOS 17.4.1 with iPhone 12 Pro. Went from 100% to 12% in 3 hours! Had no problem before the update. I will change my battery this afternoon with Apple and I’ll keep y’all updated.

I did change the battery and it’s a lot better. Very weird… Still using my phone as usual to confirm my claim. I’m may have a tin foil hat, but it looks like targeted drainage, to either change the phone or replace the battery. $

I freely do not think that such a mess is intentional. Many iPhone users (included myself) have moved to iOS because of the allegedly good battery life of iPhones as compared to Google Pixel devices and because of Apple's more sober approach towards AI applications. If Apple starts making compromises on battery life and implementing silly AI gimmick, I will move back to Android. For the time being, I have frozen my plans to buy a new iPad until the battery drain problem in iOS is fixed and Apple comes out with meaningful iPadOS upgrades. Samsung also make nice phones and tablets.

Yeah problem is not phone/hardware. There is definitely something in 17.4.1 causing the battery charge to be drained in less than 70% the time it took prior to moving from iOS 16.

It has to be an issue with iOS 17.4.1.

This morning my phone dropped from 98% to 21% in less than 2 hours or low use.

Same here- specifically YouTube since 17.4.1 and phone feels warm also.

Well, just so you know, I forced restart my phone five times, have shut off any extras, that are even small extras; my phone is draining faster than ever especially after 17.4.1… Someone needs to fix this now as I’m not ready to go to a Samsung

iPhone 13 Pro, battery health level 95%. Since "upgrading" to 17.4 (now 17.4.1) I need to recharge my device at least twice a day. Before upgrading a full charge used to last about two days, I am not a power user. There is obviously something very wrong with 17.4 or with the upgrading procedure, will try to reset-recover and report...
