Are there any known issues with the iOS 18 Update?

I have an iPhone 13 Pro. I’m running 17.7. Are there issues with iOS 18 that might delay updating? Should I wait until a patch comes out or is it safe now? My biggest concern is the handset hearing up and battery drain.

iOS 18 is generally stable, but as with most major iOS updates, early versions can have bugs that get patched in subsequent releases. Some users have reported issues such as increased battery drain and occasional overheating with iOS 18, which is common after big updates as the system re-indexes files and apps optimize themselves for the new software.




If your primary concerns are heating and battery life, it might be worth waiting for at least one or two minor updates (such as 18.0.1 or 18.1), which typically address these early issues. However, if you’re eager to update and willing to monitor battery performance and app behavior closely, it should be safe to install now, keeping in mind you might need to tweak some settings (like background app refresh or location services) to conserve battery.

Was your device Jailbroken? If that's the situation, please be informed that attributing the issues to iOS updates may not be accurate.


I have been updating my devices ever since I bought my first device in 2009. iPhone 3Gs, 4S, 5, 6, SE (1st Gen), 7, 8 and iPhone 12 Pro, iPad Pro, iPhone 13, Macbook Air 2019, MacBook Pro 16"




I never had any issues with any iOS, iPadOS, or macOS updates to date.


I would personally recommend everyone update their devices instead of listening to rumors from people who may not have kept their devices free from any spurious software.


iOS / iPadOS devices cannot be hacked or infected with Virus / Malware / Spyware if it is updated to the latest iOS/iPadOS unless you have intentionally downloaded spurious software or unauthorized apps directly from the internet and installed them on your device or/and have Jailbroken



iOS updates generally aim to enhance user experience, boost security, and fix bugs rather than disrupt core features. Issues after updates might stem from underlying, unmentioned factors. Updates won't typically alter personal data but may refine settings or features. Backup before major updates for safety. Review Apple's update details and backup advice for a smooth process.


This seems purely coincidental so please check the Setting on your device.



See what each update does: About iOS 18 Updates, About iOS 17 Updates, About iOS 16 Updates, About iOS 15 Updates, About iOS 14 Updates, About iOS 13 Updates, About iOS 12 Updates, and so on...

I am abroad on holiday and although I can get full service over the hotel secure Wi-Fi I cannot get any emails WhatsApp etc over cellular even through my wife ( iPhone SE same as mine but running 17.7) gets full service and her battery lasts twice as long as mine. I am on 18.0.1 - stupid mistake updating to iOS 18.

Apple should provide a return option for major unproven updates

After updating my iPhone 15 Pro Max to ios18, my phone suddenly draining 5 to 10% of battery charge overnight even if Im not using it. Before I update to ios18 it stays to 100% battery charge for almost 24hours if Im not using it, but now on ios18 in less than 12hrs without using the phone after I charged it, it will instantly drain 5 to 10% of battery charge.


When I checked the app that consuming the battery charge, it says the "Home and Lock Screen". But most of my settings are off and Im not using bright wallpapers, like I don't know if it's a bug or something, also from 99% battery health down to 98% with 34 charging cycle in 6 months. Seems like updating the latest ios everytime speeds up the battery degradation. It's so disappointing!

If you do a "search", you will find negative results......no matter what iOS version that you are looking at.


That is simply because users who are not having any problems very rarely will report that fact because 99.99% of users are not having problems.


Remember that this site is like a hospital. Everyone here has a problem. Only a tiny fraction of people are in the hospital at any given time though.

iOS 18 is alright, but all the apps are now trash. You can’t check mail on WiFi, fast battery drain, google chrome won’t browse the web on WiFi, iOS randomly locks up in the middle of switching apps. Siri is confused understanding speech or doesn’t work at all. Using my iPhone 16 pro, I get 12 hours of battery life, max! My iPhone 13 worked better with battery life. I might switch to pixel 9. Ehhhhh

iOS 18 is horrible. It messed up everything on my phone including the files in my apps. It deleted my files, it keeps glitching out, it won’t search anything. The photos app update is horrible. It was great the way it was before. Apple keeps making things worse not better. I am more and more disappointed every time I update my iPhone. That I don’t want to update my iPhone anymore. Everything glitches with iOS 18, even the setting app is confusing now. And I can’t just use my cellular data or WiFi either one my phone glitches and nothing loads and keeps logging out of my social accounts and other apps. And that just because I have downloaded music I have no storage on my phone because music all of a sudden takes up so much space that it wants me to delete basically everything else or delete all my music. I’m seriously considering switching.

my only problem so far which to me is a biggie, i transfer the files from my phone to my windows pc. I have done this since 2012? i can then go back and access these files and delete off the phone, my own icloud so to speak. Since the upgrade the .MOV files can no longer be seen as thumbnails in explorer and have no Length, all files prior still can be seen, if im looking for a specific file the thumbnails saves me opening 1 hundred files to find the 1. i also sort in length as this can save me time too. I also delete .mov files with no length (jpeg live files)

Me, neither. I can't recall ever having a major issue.

AND I've never been abducted by aliens, I think. I couldn't resist :-)

But would you really know? ;-)
