iPhone 11 Pro getting HOT

I have read through all posts and want to offer my 2 cents

My iphone 11 pro was normal until I started using the keynote app. It heated up real fast to a point that it is uncomfortably hot (within 1 min). Whenever I switch to other apps, the phone starts to cool. If I switch keynote on, phone starts cooking again. That’s obviously very weird, then I found this thread.

So following the discussion, I made sure my iOS is up to date on 13.1.1. Then I checked my “battery” tab in the settings, 10 min of using keynote consumed 15% battery, while the whole day of using other apps only make up 85%. Keynote is essential to me in my job, so deleting it is not an option. I also didn’t want to “reset all settings”. Instead, I closed settings>general>background app refresh. That totally fixed the problem

To sum up, here is what you can do if your phone is heating up abnormally

1. make sure it’s running the latest iOS
2. check which app consumed the most energy under settings>battery>battery usage by app, delete the problematic app if it’s not essential
3. close the “background refresh” of that app (check other battery saving tips online, it could be other tricks)
4. if none of the above worked, reset all setting (settings>general>reset>reset all settings)
5. still no luck, contact apple for replacement

If the phone came in new and you are restoring from a previous icloud backup the phone can get pretty hot during a restore specially if at the same time is charging. Second thing to pay attention to is the case you are using, some of the rugged cases can raise the temperature as they do not allow for correct heat dissipation. Finally process intensive tasks such as playing games or watching HD videos, trascoding videos etc raise the temperature of the cpu and gpu.

If the temperatures are constantly high then I would advise a factory restore and if things do not rectify a visit to your local apple dealer is advisable.

I know this is an old thread, but I would just like to help out some users that might have this issue. I upgraded to an iPhone 11 from being on an XR previously. I restored from an iCloud backup. Upon using the phone, I noticed that my phone was getting considerably warm during very light use. Just checking texts, email, etc. My battery was much worse than what it was on my XR because of this. I tried everything to try to fix from hard reset, disable background app refresh, nothing seemed to help. Anyway, what fixed it for me was opening the settings app, tapping general, reset, then tapping, erase all settings. This resets some settings on the phone to the default state. What I assume happened is there was some background process/setting causing the iPhones CPU usage to be abnormally high. My battery is so much better now and looks to be better than my XR!

UPDATE 1: After coming home from the gym and talking with apple support. I went and did a restore through my computer w/ Itunes and than proceeded to restore my phone. I let my phone charge to 80% for the rest of the day and did not have an issue what so ever. upon waking up at 0700 and my phone being 100% it was not blistering hot and did my same morning routine with a little more extra after running 6 miles with my run keeper up doing constant updates and spotify running my phone was not hot and the battery is down to 64% at this moment. I believe that it did fix the issue with the overheating but with apple boasting about the 17 Hours of battery life with video playback i am skeptical. I hope this helps every one.

I just picked up my iPhone 11 Pro and after restoring from iCloud it is seriously warm.. what is up? What is the definitive answer from Apple on this?

Restoring from iCloud is almost constant CPU and WiFi usage, which means a lot of internal heat builds up.

Then, after the restore completes, all the Spotlight indices must be rebuilt, which will also generate heat.

Check it again after 24-48 hours and see if it's still warm; what you describe is pretty normal.

Yes, for the first day after restoring a new phone or after installing new iOS releases, the phone may work harder than usual and as a result may feel hotter than usual (and use more battery) as it needs to rebuild all its internal Spotlight indices.

Once 48 hours have passed, if it is still an issue check under Battery to see whether a particular app is using a lot of power; if it is, contact that app’s developer.

Ttoday is 7/420-I received my phone 7/2-noticed right away While I was setting it up and transferring data that it gets abnormally hot. Will contact Apple; this is not normal. I don't even have it in a case yet, haven’t even streamed music or video, what happens then? I paid waaaaay too much for this phone to be having issues right out of the box...

Have you had this model phone before? If not, how can you state what is normal or not?

During set up and while transferring data it will get hot, you're using the CPU as near 100% as you can get, plus the phone's radios are also being used 100% of the time.

Once setup is complete, it will be much cooler in normal use.

You're not necessarily having issues, you're just asking it to do a lot more than you would under any other circumstance.

This also happened to me after a few months of having my phone. I did a hard restart. You can look it up, and it took me a couple of tries to actually do it correctly, but it’s simple. You quickly hit the volume up button, then volume down button, then the power button. It will not ask if you want to power down, it will just automatically do it. My phone is back to normal. Hope it works for you!

I’ve had my iPhone 11 Pro for a few months. This has also happened to me 2 different times. Both times I was able to fix the issue immediately with lasting results by doing a hard restart. You can look it up, but it’s not too hard. You push the volume up button, then the volume down button quickly. After, immediately hold down the power button until the phone turns off on its own. Do not push the button on the screen when it asks you if you want to power off. Just wait until it turns off. This has fixed my phone both times. I believe it is the answer. Hope this helps!

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!

That’s what I say too ! It isn’t normal at all! I did go back again to the sprint/ TMobile . This time they told me the same they said before that the battery looks good but also talked about sometimes app stay on in background . He explained what to do and I asked if he could do it and explain to me again what to do . Hopefully that may help , he went to setting , screen time then scroll down to app limits. Then turn on . Then ya pick how long . He suggested maybe do 3 hrs every day .so that’s what I did he explained that this just limits how long the apps can run in the background . Evidently my Facebook page was running In background for around 20 hrs and it was in the morning and I haven’t been on it since the night before. He said sometimes ya go out of an app thinking ya closed it out but sometimes it’s still running In the background! Maybe y’all can try that too ! I will let y’all know if that helps ! Hoping it helps !

Return it to where you got it from and insist on a replacement.
