iPhone battery draining after iOS 18 Update

After updating to iOS 18.3.1 my 14 pro battery draining fast

Battery life has been significantly affected on our iPad and iPhones since the update, my new iphone 16 was tested in store this week in Birmingham and requires a new battery. Had to buy another new phone as they wouldn’t replace it, so the battle begins.

The vast majority of battery issues at this point are caused by third party apps. These include Instagram, WhatsApp and to a lesser extent Facebook and Messenger. Do you see a trend? They’re all owned by Meta.

Also apps showing poor battery consumption are TikTok, Snapchat and YouTube to a lesser degree.

What apps are draining your battery capacity?

I see this thread is relatively old. I have only just recently updated. Why, why, why did Apple keep rolling this out without a fix?? This is clearly not the usual post update drain. Apple this family has 5 iPhones and 2 iPads. Ready to switch horses here.

Since update 18, my battery is draining very rapidly. Has Apple done this deliberately?

Battery halt life time

I’ve tried all the suggestions and I think it’s just getting worse, took it off charge at 7am at 100%, it’s now 18:26pm and I’m on 56%. That’s 44% battery with only 30 minutes screen on time, no background activities, on a 16 pro max. That’s garbage.

im going back to android.

Hey, so just a quick update: I think i’ve managed to resolve the issue! Yesterday I checked my photo gallery, scrolled all the way down and noticed “optimizing gallery” at 76%. Force scroll down once or twice just to be sure. Apparently, it was stuck for me. First clue were double albums generated in my photo app (memories, trips, yearly etc.) so i decided to check icloud sync as well and force start the sync, but it did not work at first. I decided to manually delete few blurry images that appeared in my gallery (clearly they were stuck at some point and were easy to distinguish, mostly). I deleted some duplicates from library, deleted all generated albums and memories (original photos remain untouched). Once again kick started library optimization simply by plugging in the charger, leaving wifi on and locking the phone, i kept photo app open just in case. What happened after surprised me, last 24 hours 5% usage from home and lock screen. Hourly usage is not in double digits anymore, i have 2-8% hourly usage, few intervals it shows no usage at all. I think the issue is gone but it might be too soon to tell. In case you haven’t tried this, do it, triple check if there’s anything stuck syncing/optimzing. Fingers crossed this helps you and anyone dealing with this frustrating issue!

Same problem continues. I’ve gone through every app on the phone turning off everything not needed. Messages is using 42% of the battery as that is most of what I do. I upgraded three weeks ago so it cannot be “working on upgrades”. I have a 13 and do not even have Apple AI and have turned Siri off to the extent I can. Logically if the battery lasted a day and a half with my style of usage before the update and literally the only change was the update, this is not a me issue. Given some recent developments with Apple I will stick with them but come on folks, this needs to be addressed.

Hello~ Apple Intelligence will not be a factor because your iPhone 13 is incapable of using it. Click on below and review everything there…
