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 checked my battery usage in settings and saw an app (dictionary.com) was constantly running in the background. It had used 85% of my battery and my phone was getting so hot, it wouldn’t charge. I killed that app and that fixed the problem. So you may have some random app running in background. It was a simple fix so helpfully that helps.

Before resetting, check your battery usage is settings and see if there’s an app continuously running in the background. If so, change it and that should fix it. That worked for me. (I had an app that used 85% of my battery.) Hope this helps.

Go to Settings -> Battery and see if anything is using a lot of battery.

To provide an update, I went to the apple store this morning. They had not seen my specific issue prior to today, but ironically, there was another person there at the exact same time with the same complications. To recap, working fine... then a message stating the phone is overheating (despite not being externally hot to the touch)... then the battery not being recognized as a genuine apple product and no longer able to charge or connect to a computer. At the apple store, they tried several methods to reset the phones, but were unsuccessful with both phones. They ended up replacing the phones. Hopefully this helps someone else.

It will take up to a day for the phone to rebuild all of its databases and indices during which the phone may run hotter than normal and use more battery.

Use it normally but don't worry about the heat until a day has gone by, and even then it's not an issue unless the phone shuts itself off due to overheating.

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!

First, if nothing else, Apple has a 14 day return policy if you are unhappy with your phone for any reason.

Among other things, your iPhone 8 had a slower CPU and had a completely different design (LCD vs. OLED screen, home button, different case materials, etc.)

Have you looked at Settings -> Battery to see if there are any runaway apps causing your device to use more processor power than usual, causing it to warm up?

Historically the Facebook and Instagram apps have been two of the largest battery users.

What are you doing when this happens? I have an 11 Pro Max myself and I can guarantee you that in normal usage it doesn't get "hot" within a few minutes; if I am editing video, of course it does, you're editing 4K video and most desktop computers can't handle that workload.

These aren't just phones anymore, they have more power than a laptop did just a few years ago and iPhones don't have fans.
