iPhone feels warm after iOS 18.6.2 update

I recently (about 3 days ago) updated my iPhone 13 Pro to iOS 18.6.2 and my phone feels warm to the touch, which did not feel this way prior to iOS update.

I powered off my phone last night around 10:30 pm and powered on my phone this morning around 8:30 am. After about 10 minutes, my phone still feels warm.

I removed my phone case because case felt warm and even without phone case, my phone still feels warm.

Has anyone experienced this issue since updating phone to iOS 18.6.2?

Thanks!

It's not unusual after an update and even a few days after, depending on how much data is on the phone, for the phone to feel warm. Phones need to index the millions of bytes of data after an update. It would be good for you to do what WheelieNick suggested, which is to Force Restart your iPhone (I do this after EVERY iOS update, EVERY TIME).

Another thing to consider is what your Battery Health is at this point. Depending on when you bought your phone (they were released originally 4 years ago, in 2021). If you bought your iPhone when they were originally released, it's highly probable that if you still have the original battery in your phone, it's time to replace the battery. Open Settings > Battery > Battery Health. If it is 80% or less, the useful life of the battery has been used and it's time for a new battery, which you have installed at your closest Apple Store Genius Bar.

Thanks a lot, as I’ve mentioned, the battery was replaced by Apple for free (curious why, considering the warranty is expired, and I came absolutely willing to pay). Also now when battery is at 100% the phone still heats up a lot during charging and when using Safari (and whenever else, I can’t fully see what causes that). It was never like this before the recent update. And yes, the internet is flooded with complaints.

& another thing - my hand is on fire holding my phone. It’s like hot potato. Something is absolutely not right. I have a brand new phone and this is happening. My battery is drained. My hand is seared from holding it. Feels raw. Apple is up to no good. I am not buying a new phone nor trading this one in so don’t even try

So you're phone has been overheating since at least September 3rd. What did Apple say when you contacted them?

I thought as much.

Thanks much!

Nothing happens when I follow these instructions. Pressing and holding the side button brings up Siri and no Apple logo appears.

Oh wow!

My Battery Health is at 78%, but I’m not sure if that’s before or after the iOS update. Nevertheless, I read a message that I need to replace my battery.

So, how is your phone doing now after the new battery was installed last week?

I'm curious, how old is your iPad?

I bought a new iPad (10th generation) last year, but I have not used it as much lately.

Thanks

That usually solves the problem along with resetting network settings ..

phone still gets hot with web browsing, and normal activities..

Same here. I can’t even figure out what exactly causes the heating up. It’s not video, Safari - yes, but not always. Definitely heats up more when charging. I never noticed that before.

Well it heats up sometimes, especially when charging. Never happened before. But so far the battery is ok.

Interesting, I would like to know what happens after your appointment with the Genius Bar.

Sep 17, 2025 3:31 PM in response to AlanK1977

The exact same thing is happening to me. Just a minute after installing the update, my phone starts heating up and the display dims down to 70%. It's so annoying.

After a update a couple days ago my phone is so hot and won’t cool down
