iOS 18 draining my battery
Last night (17/09/24) I upgraded to iOS 18 update but this morning when I started using the phone, my battery drained out very quickly - anyone had similar issues.
any solution please ?

iPhone 14
It’s the photos app. I’ve had things like background app refresh, dictation and location turned off for years. I have about five (non Apple) apps installed (no social media or entertainment type) and I use my iPhone 15 Pro primarily for talk and text which never accounts for more than 5% of my battery use, even on a heavy use day. I went from holding a two day charge to charging twice a day immediately after iOS 18. I noticed in Battery Heath that Photos was using 32% of my battery in the background which was alarming because I don’t use Photos in that capacity, and for the fact that I have background refresh disabled. My solution was to turn cellular data off for Photos entirely. (Settings > Apps> Photos > Cellular Data> toggle off) It’s been about a week and my battery is holding almost the same charge it did pre-update. I hope this helps!
Apple has essentially overhauled the utility app into their own version of social media, riddled with unnecessary AI and it’s working as such. Imagine it as uploading 5,000+ photos and videos to Instagram all at the same time. As long as you connect to WiFi periodically, your photo’s will continue to sync to iCloud. I don’t use the app much, but I can’t find any reason to have Photos running on cellular.
Side note: I do not connect my iPhone to WiFi on a regular basis. If you are constantly connected to WiFi, this fix likely won’t work for you as the app will continue to run in the background via WiFi and there is currently no way to disable this function (hence the issue).
The only true fix we had for my wife's Iphone (pixel user here) was to toggle off anything related to learning, suggestions and Siri, entirely, along all apps. Seems logical since the update is mostly related to Apple's preparation of the AI rollout.
Try it and hopefully it works for yours, too.
Teams is a huge battery sucker, but I do agree with you. It shouldn't be different than before you updated.
have you tried turning off Siri learning from your apps? This seems to have helped me quite a bit on my 14
My wife had zero problems when her 13 mini ran on 17.6, 17.7 then on 18.0.1. After updating to 18.1 the battery life halved or so.
I restored her iphone to 17.7, zero battery problem then, later to 18.0.1, zero battery problem again.
I am happy that not IOS 18 as a whole is a problem, because she did not make a dedicated backup when 17.7 ran, so I was unable to fully restore her phone settings with 17.7.

you have to turn off all AI functions. That’s what’s draining the battery. Once I did that, my phone has been fine. You have to toggle each individual one off, which is annoying, but it’s the only way. The software is constantly supporting the AI in the background. Settings>AI&Siri> Apps> shut all functions down specifically “Learn from this app”. Your battery will be back to normal. Thank me later
Over 70% of your battery usage is from third party apps. Make sure you’ve updated to the most recent versions of those apps. A test is to delete those apps first 3 or 4 days and look at your battery usage by app.
I think I found the solution for this, still testing, but no sign of battery abnormalities - excessive heat, draining, etc
+ deplete battery as u use iPhone till power off
+ leave it for couple hours
+ fully charge it to 100%
+ do previous steps couple times
this should do the trick
extra tip: use genuine power adapter and cables
Is it the Apple cable that came with your iPhone and is it an Apple branded charger? What is your battery usage by app for the last 24 hours and 10 days? Please post a screenshot similar to mine below from earlier today.
What is the Battery Health of your 10XS Max? Your iPhone was introduced in 2018 and discontinued in September 2019. Your iPhone is 5 to 6 years old and if you haven’t replaced the battery and it’s still the original battery, it’s over 5 years old at a minimum. Lithium batteries have a life span of about 5 years and from your description of the charging performance it’s reached the end of its life. There is nothing unusual here. Have your battery replaced by Apple or an Apple Authorized Service Provider.

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…

Have you forced restarted your iPhone?

What version of iOS are you using?

you can downgrade to 17.6.1 as signed copy available for download, you can restore through iTunes
The hotline helped me. It was enough to start the update again to ios18 from safe mode. So far it has worked and the battery is ok
Hello~ Since downgrading to a lower iOS is not supported …click on below and review…

I also had this problem. It wasn’t fully charging either. I turned off the optimized battery charging and it is charging much better I’m thinking that might be part of the problem.
Turn off sound recognition under accessibility
You don't say if you've done a forced restart. I'm sure you probably tried that already, but if not, give it a try.
