iPhone 11 Pro getting HOT

My Pro max got very warm the other day after the phone rang. I turned it to silent and slipped it in my pocket. A half hour later I took the phone out from my side pocket to find it very very warm and shut down. The phone would not turn back on without a master reset. This on IOS 13.1. Once the reset process was finished the phone cooled off and was working normal again. This kind of thing never happened with my Xs max. I’m still a bit concerned however.

To be blunt, your XS Max was likely not running iOS 13.1, so the likely runaway third party app was not in fact running away under iOS 12.

Ultimately as vendors fix their apps this problem should go away quickly.

Which is why once the phone exceeds a certain temperature, it will shut down.

Otherwise there's nothing Apple can do without depriving apps that actually need it of the full processing power of the chip.

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.

That is not at all normal unless you only have one bar of signal strength.

I have made several cell phone calls of over an hour in an area with three bars of signal and my phone is barely warmer than room temperature.

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.

Facebook has been a battery hog inducing high CPU loads (and high temperatures) for years now, mostly because it's constantly downloading and keeps track of where you are via GPS and often is displaying animated content even if you are just scrolling through your news feed.

You are no help I’m not even sure why you are commenting. The point is that these apps should work without the phone getting so hot. I have owned IPhones since the first one. This has never been an issue no matter which app I was using.

None of my apps used excessive battery and my phone was getting hot. It is not a “runaway third party app.” When people are saying their phones were hot right out of the box, pre setup it is not a third party app that is causing it to heat up as you keep suggesting.

You act like jshaneevans isn’t allowed to comment. He’s allowed to comment just like the rest of us so I don’t know why you’re so worked up over it. He’s suggesting that certain apps shouldn’t be causing the phone to over heat and I happen to agree with him since that isn’t the problem on my phone.

I think it’s Spotify. I was listening to Spotify on my way to university today with the aux cord plugged into the adapter into the bottom of my 11 pro and my phone got really hot and the battery drained from 100%-76% in about 20 minutes. Spotify was the only app running, I closed all others.

Wow—so glad you posted. After my iPhone 8 fell in the river, I decided I’d upgrade to 11, and this heating bothered me so much. I teach ESL online using my iphone and use the teaching app with a heavy video connection for as many as 7 hours in a row (average 10 hours of video classrooms a day). This is why I bought the 256gb Pro Max—I depend on my phone for work. However, after my first full day of classes, I’ve been disappointed. The phone not only overheated to the point where I could barely touch it, it started lagging and slowing down towards the end (when the heat got bad). After I signed off for a while, it cooled down and sped up again. This was NEVER a problem with my iphone 8s plus, and I used that with the same video teaching app for the same number of hours (I taught almost every day on it for years, 8 hours in a row—no issues with it overheating or lagging). With the iphone 11 pro max, I could barely use my stylus due to lag while heating...

It IS a problem for a lot of us, not only because it is getting too hot to hold (I use a hands-free stand while working on my phone). It is getting hot enough that it is causing the cpu to slow down and lag!

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.

Same here... the factory reset isn’t the issue. I did a reset yesterday. I also updated ios to 13.1.1 yesterday. BTW, just called Apple support and they ran diagnostics on both phone & battery, nothing unusual detected, but they do admit this is not normal... I have an appointment at Apple Store Wednesday for a full hardware diagnostic now. Will keep everyone updated.
