iPhone battery draining after iOS 18 Update

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 ?

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).

Here’s the deal folks… If you want to know the truth, it is evident that Apple is exploiting its iPhone users to do one of two things. 1: Is to force the iPhone owners to upgrade their phones and 2: Is to force them to purchase new batteries. A new battery can cost a minimum of $125.00 and we already know how much a new phone will cost. I purchased a used battery with 92%, almost new. I had 2 iPhones one of which is used by a friend a when I gave it to her in June 2024 it had more than 80%. At the same time my daughter gave me her 13 Pro Max with battery @ 86%. After we both upgraded our phones to iOS 18.1.1 the battery percentages were exactly the same 74%. This is not a coincidence… the messages said that our batteries were at a point that we needed to replace them.

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.
