Are you guys sure this is not linked to a third party app you both might be using, which might have not been optimised for iOS 18 yet? What happens when you look into Settings > Battery usage by apps?

They have gone over this suggestion and updated all, rebooted, etc. It’s weird because my iPhone 15PM was never warm on 17.XX but then got hot on the first 18.1 beta then was fine on the next two.
So it’s either a marginal chip or corrupt app or software.

The app at the top of my battery usage is X formally Twitter. I get heating issues when using stock apps, photos for example and when editing wallpapers & Home Screen. May do a reset and restore after the next beta/RC if no better.

Mostly with using safari and macrumors

Is there a way for you to get on the 18.1 beta? I’ve been using my phone an hour straight after rapid charging and have no heat issues at all.

If not, annother option would be to reset your phone and reinstall everything again.

Make sure to backup your iPhone before doing a restore. Don’t do it if you wear an Apple Watch ⌚️ and run watchOS 11 beta on it.

I’m probably switching everything back to my 15pm 18.1 beta 3 from iPhone 15 plus 18.0 beta 8 …I have watch OS11 linked to my 15 plus, you’re stating even if I reset the watch it won’t connect to my 15 PM?

No there’s no way and I don’t want to run 18.1 beta.

You mean wipe it in the system settings right?

I think I’ll wait for the RC next Monday

If it’s 18.1 to 18 you are fine man. An Apple Watch running watchOS 11 should pair to any iPhone running iOS 18 or 18.1, subjective to ensuring that a backup is done prior to restoring your iPhone.

Just giving you a heads up in case you go back to iOS 17, as it will be a different experience. And unless you have an Apple Watch to spare that is on watchOS 10 you have to bring your Apple Watch to the Genius Bar to downgrade at your Apple Store. Depending on the series of your Apple Watch, the Apple Watch will need to be downgraded via a diagnostic tool.

Thanks. I’m staying on 18—my watch is Apple Watch OS 11 and going from 18.0 to 18.1

So weird that this beta did not impact my iPhone XR’s battery health max capacity. It always stayed at 82% maximum capacity as I had it for almost a year (lightly used from launch day from its original owner) despite draining battery in the first few betas. Beta 8 is the most stable of it all.
 
Using safari for less than a minute and my 15 PM starts to get warm/hot…
This is so strange and I hope this ends with the RC next Monday
 
I don’t know if this is a bug or a feature.

When I’m downloading a profile, for example from dnsforge.de, it doesn’t show it downloaded inside the iOS settings until I’m not opening it inside the documents app. Until iOS 17 I’ve got a message in Safari that the profile is downloaded and I have to install it in the settings. This only happens in iOS 18, when I’m trying to open it inside the documents app.
 
During the night, my battery dropped from 65% to 6%. I've been using beta versions since the iPhone 5, and this has never happened before. Should I wait for the RC, or is it better to factory reset my iPhone?
Obs: I’m using the last iOS beta since the release date.

What I would do if I were you, listed in order of simplicity:

1) Make a full encrypted backup of your iPhone on your computer;

2) Once iOS 18.0 RC is out on 09.09, first try updating OTA. It is a big file (could be around 6GB in size, so if your internet connection is not optimal, skip straight to step 3);

3) Update (not Restore) with IPSW file via Files on your Mac;

Now test drive it during the gap between the RC and public release. If all is well, great. If it still overheats (and this might have something to do with a non-optimised app installed on your iPhone), you might consider:

4) removing your most frequently used 3rd party apps to see if this makes a difference.

5) If step 4) still does not resolve your heat issues, then go radical and restore your iPhone (wipe everything off and install the latest iOS 18 public version). Try using it as is (empty) without restoring anything from the backup yet. If it works well, start populating it with your date. If the heat is still present on your freshly wiped iPhone without anything extra installed, take it to Apple for evaluation to exclude any hardware issues.

I moved everything from my 15 Plus to the 15 PM because my company unlocked my phone (now I can carry one phone)---transferred everything via icloud, apple watch came over and the 15PM did not overheat at all---even with two hours of updating/downloading and charging. My watch paired up no problem as well.....
In case you have no other choice it's an option.. :)
