iPhone 11 Pro getting HOT

I have this problem with my iPhone 11 after wireless charging. It only started happening after updating to 13.1. It worked fine while charging since I received the phone on the 20th, but started the issue after the 13.1 update. I noticed that there was an update to the "optimized battery charging" feature in 13.1. To test, I disabled the feature last night, and the phone did not get hot as it did previously. I'm going to re-test again, with it enabled to see if it makes a difference. I've spoken with Apple Support and opened a case ****. If anyone else is having a similar/related heat issue, it may help to refer to this case if you speak with them.

If it's warm like that and the battery isn't lasting long, sounds like it's working hard. Were you restoring a backup or anything? Might not be anything to worry about unless it's shutting itself off like someone else mentioned, but if it doesn't change after a few days might be worth going to the Genius Bar and/or exchanging it after finding out if it's wonky software or not.

Check Settings -> Battery and look for any apps that are using a lot of power.

Since wechat is an audio/video chat service, and there are few apps that would use more power than that, I suspect it may well be the culprit.

People are reporting normal usage and the phone is becoming excessively warm from charging to just normal scrolling in Facebook, that is the issue. Now I had the same issue and I did full restore from iTunes and it seem to fix the issue. However, some people are refusing to try this simple fix because they are lazy and demand that they need a new phone. To sit there and say that if the phone doesn’t shut down from the Heat isn’t helpful what so ever.

Maps in particular uses a lot of power because it's constantly interacting with the GPS hardware whenever it is running.

Music may, depending on where your music is stored, be constantly downloading from the Internet.

Settings -> Battery will tell you precisely how much power both used.

Doing a factory reset on my phone didn’t work. Doing the 13.1 software update didn’t fix the issue either. Strangely, a “reset all settings” did help a lot. I think it’s because I didn’t carry over my original settings as I did with a factory reset. My phone isn’t getting HOT anymore but it warms up still after several minutes of use which I’m still uncomfortable with because my 8 plus never did that and my sister got the 11 pro max as well and said hers never even gets warm with prolonged use. So my suggestion is to do a “reset all settings” and see if that helps. I updated the software to 13.1.1 yesterday and phone is still getting warm maybe even more now than with 13.1. I encourage everyone to call Apple and open a case with them, they need to know about the problem because this is complete BS. Also, if you are noticing your phone dimming on its own there is ridiculously two “auto brightness” settings. One in Display and one in Accessibility. You’ll notice when you turn the one in Accessibility off it stops dimming on It’s own and your phone brightens up considerably. I was wondering why my 8 Plus was so much brighter.

Well then you have two choices:

1. Try to diagnose the issue. What apps if any does Settings -> Battery show is using a lot of power? Certainly I do not experience this using Safari to web surf, but it also depends on the sites you are visiting.
2. Return your phone for a full refund under Apple's 14 day return policy.

I ended up going to the Apple Store and returning my iPhone 11 because I didn’t want to deal with this issue anymore—I downgraded to iPhone 8 plus (my original phone that I lost). However, after I got home, I realized that my iPhone 8 also had the same problem with my teaching app. I believe the problem was incompatibility with the 13.1.2 update to iOS, especially since there were about 3 updates in one week, which was not enough time for the software developers of other apps to catch up with updates (including my teaching app that I depend on). I had to go through yet another hard reset. I lost a lot of date in the process (since I couldn’t use my most recently saved backups, which were already made with the new iOS), but no problems with the apps or overheating after that . This is just too many iOS updates in a row, Apple! Anyway, it was a huge amount of trouble to go through in a week, not to mention spending hours on the phone with Apple Care customer support every single day. It was really a nightmare. I believe a lot of the issues people think are hardware problems with iPhone 11 are actually software problems with the new iOS. Apple needs to give apps a chance to catch up before putting out so many updates in a row!!!

I can use Facebook for hours without my iPhone 11 Pro Max becoming even slightly warm.

Have you checked Settings -> Battery to see if anything is using a lot of battery on your device?

Note also WiFi is less power intensive than cellular, especially if your cell connection is three bars or lower, as the transmit power on the cellular radio needs to be increased to compensate, and that generates heat as well.

I called Apple. After speaking with 4 tech people we finally did a full restore on the iphone using itunes on computer. I then started from scratch on the iphone and downloaded a backup from the cloud. That worked. Now the phone is loading the apps without getting hot. Mine was BRAND NEW iphone (iphone 11 pro max) was SOOO hot I could not hold it. Absurd and a tons of time to fix, but fixed. The RESTORE was very specific. Have phone plugged into computer and hit vol up, then vol down, then hold right hand button until picture of a cord comes on. Then tell computer in itunes to restore (popped up on screen) then update and restore. Then set up phone from scrach and at ground zero. It took 4 apple techs before finding the one who guided me correctly. Although he said I had download all apps from scratch and that was wrong! I did download from cloud. Call Apple. Ask for a SENIOR tech person.

HI all,

just wanted to add that my was red hot with WeChat, and now only gets warm during WeChat use and that's occasionally. The latest iOS updates and the actual apps update fixed everything for me.

cheers

This is being said over and over again but is not the answer. The point that is being made is that this never happened with other versions of the iPhone and is now happening with the iPhone 11.

That is completely inaccurate; in particular the Facebook app could often turn my iPhone XS Max and before that iPhone X into little space heaters.

When CPUs are being used at high percentages, they generate heat, that's the way processor cores work.

When something causes the CPU to be heavily used, the phone will heat, and the easiest way to tell which apps are responsible by looking at the commensurate amount of battery they use.

Were it an issue common to all iPhone 11 Max phones they would all do it, and they do not.

iOS 13 also does not run the CPU at 100% all the time in use; I can use my phone to web surf with Safari for hours at a time and it is barely warmer than ambient unless I am watching a lot of video content.

As is always the way with bugs they don't affect everyone on every device.

Wether it is down to a configuration issue or a chipset issue within a particular model (the same model can have different chipsets) I like many many thousands of other people, don't know.

To my knowledge the problem overly hot/battery drain problem affects iPhone 6, 7, SE, 8, 10 & 11all of which are running IOS13.

Download the "Status" app from the app store, close all your apps, reboot the phone put it into Airplane & Low Power mode & have a look at your cpu in Status.

Restore your phone to factory default with no other configuration ie do not log into your iCloud account or add any email accounts but connect to wireless & browse the apple news app or the internet, does it still get hot?

If so the cpu is running excessively high with the basic IOS which is wrong

This is a brand new device, so no, you don't know what is normal for it.

These phones have much more powerful processors in them, which generate much more heat when they are heavily loaded.

Also, especially during an install of a new phone and after an iOS update, you can expect high CPU usage and shortened battery life for about the first 24 hours as all the Spotlight indices on the phone need to be rebuilt so you can find things when you search.

If the phone didn't shut down because it got too hot:

it's within the normal operating parameters for the phone.

Same thing happened to me. Get a replacement. I did. So far- one week- hasn’t been running hot., unlike how the first phone behaved. Still, I’m wary and I hope this new one is not a lemon, either- good luck!
