iPhone 7 Overheating

My new iPhone 7 overheats as soon as it starts to play video, download files, or play music. It even heats up when I'm taking photos.


I found the following article given a fix. I reseted the phone and started as a clean, new phone setup and still heats up.

Here is a quote of the article:

How to fix the Apple iPhone 7 and iPhone 7 Plus overheating problem with these solutions:

  • There could be a good chance that a third-party application is the cause of the overheating Apple iPhone 7 and iPhone 7 Plus. The best way to check this issue is by holding down power and Home button until the screen goes black then remove finger from home while continuing to hold power. Once you see the Apple logo-hold the volume up button until the springboard loads. If the device is in Safe Mode the tweaks will be gone under the setting menu. If the problem is gone then you know it’s being caused by a third-party app. You can try uninstalling one by one to track it down or go for a factory reset.
  • Before you factory reset the Apple iPhone 7 and iPhone 7 Plus, it’s recommended to wiPe the cache partition of the smartphone (Learn how to clear the Apple iPhone 7 and iPhone 7 Plus cache). Select on Settings > General > Storage & iCloud Usage. Then select on Manage Storage. After that tap an item in Documents and Data. Then slide unwanted items to the left and tap Delete. Finally tap Edit > Delete All to remove all the app’s data.


Is anyone else having this problem, and do you have a fix or solution?

Thanks,

Let's rank your symptoms in order of importance:


1. WiFi greyed out

2. Phone getting warm


It's a little like saying:

"I've got this itch on my back that I can't reach."

"By the way, that shark just bit off my foot"


The first indicates a serious hardware problem with your phone. Anything else is irrelevant. You should start here: If Wi-Fi is grayed out or dim on your iPhone, iPad, or iPod touch - Apple Support

There’s a 99% chance this is due to the YouTube app. This happened twice in the past 11 months, both after an iOS update. If you read the rating/reviews of the app in the App Store you’ll read many people reporting the same issue. It’s a very common problem with this app that keeps on reoccurring. Almost makes you feel they are doing this on purpose because they hate iPhone. This is the only app that has ever caused this issue for me and I’ve been an iPhone user for over a decade.


This is the fix. First remove the app. Next do a soft reset by holding the power and volume down buttons at the same time till it restarts. Do that after the phone batter has completely drained and you have fully charged it. Remove from charger after the phone restarts. Simply removing the app will only fix the heating issue, the battery will continue draining quick because it requires recalibrating.

It is only an "issue" if it gets so hot that it displays an overtemperature message and shuts down.“


You are WRONG, sir. It is aso very much an issue when the phone runs so hot that it causes the battery to drain in one hour of video playback, which has been what the YouTube app has been causing. Who’s spreading misinformation now? Except your misinformation is actually dangerous and harmful as someone might actually believe what you’re saying and not fix their phone thinking that’s normal, till one day soon enough they end up having to spend a ton of money on a new battery as the old one would have died much sooner than a battery ran in normal conditions would have. I am so done with your nonsense. Don’t contact me again.

that feature of holding a power button and home button is not working on my iPhone 7 i m running version 11.1.1! Problem is that when i click photos or take videos or play some hardcore graphics game suddenly my phone gets heat-up and it get too hot i m worried that it might have blast ! And i m not using any untrusted Apps which is under third party, Should i concern to apple service? or i should wait for the next update? (from India)

Mine started doing the exact same thing getting hotter over time, yet showed no kernel panics. Continual resets, even hard fresh installs did nothing. Went in for a swap, "genius" said not hardware related, try installing as a "new iPhone" after a full reset. This made it worse to the point it burned my hand when trying to manually sync photos outside the Apple case.


It was overheating and the screen going black/dark after calls, iMessage, etc. Not having any non-core Apple apps soled nothing. Black was a bad idea, it just makes a badly designed heat dissipation system worse. This is a known flaw.


To add insult to injury, I couldn't get a loaner phone, wouldn't sell a new one for some reason because the "Safety Team" needed to be contacted. So, I had to go pay full retail for an unlocked Android to have a working phone.

I had a problem with my iPhone 7 overheating this morning and throughout the day. I could barely use it and every minute or less, it would send me back to the locked home screen. The power was being drained at an incredible rate as well. I could hardly keep it charged. I ended up going into my settings -> general -> reset and selecting "Reset All Settings". This almost instantly caused my phone to start cooling down and all apps started working and the phone was not acting up. It also started charging again! Hope this helps someone.

I had the same today, getting hot and keep shutting down to home scree, I done what you said and it cured the proble, I then thought I would do a full factory reset and restore using an iCloud back up, it Restored ok but when it was half way through restoring the apps it went back into its gett hot and shutting down to home screen log on, I had to then do the reset all settings again and now not shutting down, I will wait for the apps to restore and do the latest update 11.2.1 and see how it goes.

Omg same thing EXACTLY THE SAME THING is happening to me right now. My first replacement they gave me had temperature issues , it showed a temperature warning icon on the screen and it was pretty scary. They replaced it for me and thought I was all good. The second device they gave me ended up having vibration and 3D Touch issues. When someone would call me it wouldn’t vibrate. The charger I received in the box randomly stopped working on this phone and it stated this accessory isn’t compatible or something like that. I returned to the apple store after one **** of a show speaking with numerous people in apple support. Finally they offer to replace it again but I had no hope. Sure enough this phones having temperature issues and also the speaker st the top randomly either shut off or went quiet and when playing music it only goes to the bottom one mostly making the audio sound unequal similar to the 6s I had where it was just down firing speaker. Now I just got off the phone with them because they said there isn’t any warranty left on this REPLACMENT DEVICE meanwhile its only 2 weeks old. Either way if they replace it or not I have no hope for this refurbished warranty. They just changed the words around I still believe it’s a referbished device. Fingers crossed , maybe fourth times the final one! I’m tired

Unfortunately Apple does not have any shops in Thailand and no iPhone service center. Despite having one year guarantee, Apple do not service or repair or exchange iPhones in Thailand, because they have no service repair center. Once you buy an iPhone here, you have no support. I found this out when i called them and they said they dont have a repair center, and i asked then how on earth can they fulfil the one year guarantee terms? The Apple Thailand assistant hung up on me with that unanswerable question. indeed, she was in Singapore, because Apple Thailand feed all their stuff to Singapore Office to handle. Singapore Apple service station wont service any iPhones bought outside of Singapore.

Same here! It was charging for a while when I picked it up to answer a skype call and actually burned my fingers. It was displaying temperature warning and was so hot that I could not even hold it.


Now when I try to charge it, even when the phone is off, it still heats like crazy, takes a day to charge till 80% and loses all this charge in an hour, even when off. Latest iOS 11.2.6. Factory reset does not help.


Dad that it's out of 1-year warranty already. Apparently Apple become one of those manufactures who design products to outlive warranty for just a little bit.

It sounds like something failed in the phone, probably the chip that controls charging. While this can happen randomly, most often it is the result of using a poorly regulated USB power source. It can also be caused by a battery that has failed suddenly, again, either randomly, or as a cascading failure due to the failed charger chip.

Mar 8, 2018 8:21 PM in response to Lawrence Finch

Thanks for the explanation! This sounds logical. I use original iPhone charger and wire, but they can fails as well.


What worries me is what could happen if I didn't had this Skype call at 2.00AM. Would it burn a hole in my table? Would it heat to a point where battery explodes and sets my house on fire? Can I sleep safe while my phone is charging?


And where I live there are no service centers capable of replacing iPhone parts (that's why I prefered Apple - their devices were proven to work for many years trouble-free in Jobs times). I'm now considering running a "test charge" with a thermometer attached and filming it. Somewhere safe.
