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

This is mostly due to the fact that the new phones are completely sealed (water resistance) hence insufficient ventilation. In addition, I believe the components are more jam-packed.


In terms of software, the best thing to do will be to disable Siri which constantly records audio in the background listening for "hey siri". Secondly, try disabling any color filters or Night shift mode if you don't really need them. Lastly, disable raise to wake settings for when the screen is locked. All these constantly run in the background making it impossible for the phone's processor to get a break even when you lock the phone.

My iPhone 7+ has had the overheat problem since before i installed any apps. The camera is also bad for my purposes because i need to take macro images of small objects very close up, and the two lenses make the focus jump left to right, and the camera makes blurry pics if close up. Indeed this is the worst iPhone i ever bought, with overheats, shutdowns, battery drains, Phone Freeze, and rotational gyroscope problems (screen rotation too sensitive).

Im still on iOS 10.2 though as i refuse to update iOs anymore, due to the fact that it is being developed ever more for consumers and social networking, and ever less for content creators and productivity. And i agree with you that Apple have a problem, as i am still using the 2012-2013 iMac, Macbook Air 13 and 11, Mac Mini, iPad, iPad Mini and haven't bought a new device since then except this iPhone 7+ (which i regret). This is because i am waiting for Apple to make a Macbook with a touchscreen, or an iPad with a Mouse. Instead, we got an overpriced Macbook weighing 4 pounds with a 'touchbar' that makes you look away from the screen to operate... and we see a certain other company with full desktop os on ipad size tablets with trackpads and keyboards and touchscreens.. Apple do have a problem indeed

If it was overheating when you first got it, you should have exchanged it immediately. If it's still under warranty, you should have it serviced.


Buying an iPhone 7+ with the expectation you could do macro photography indicates a failure to read the specs or do research.

Dear Apple developers my iphone 7 is getting so hot that it almost burning my hand. Iphone 7 is the worst iphone I have ever had:(((((((

Apple is not reading here. If your phone is overheating, you should make an appointment with the Genius Bar at your local Apple Store or at an Authorized Apple Service Provider and have it evaluated.

A recall is appropriate when there is a problem affecting a large number of devices. As there are over 100 million iPhone 7's in use, and very few reports of what you describe, it is most likely a problem with your specific phone. Not something that a recall would fix. And it's what warranties are for.


Note that any phone will get hot when being charged, used for long calls, interactive video games, or long downloads, or combinations of these activities. It isn't a problem unless it displays a message saying that the phone needs to cool down (meaning the temperature has essentially gone above normal human body temperature).

I have also faced this type of issue and it happens every now and then.

Basically problem lies with 2 things

1. Any change in settings

2. 3rd party apps

So I generally fix this by resetting any setting which I have recently changed. And it most of the time my heating issue is resolved.

Also if you are not able to drawdown which setting tone changed do not go for compete resetting.

Go to reset option and reset home screen layout then location then network (any one of this not all in sequence)and then check if issue is resolved.

However I don't feel there is any permanent fix for this it's an oscillating problem for all users.

Any issue with third party app can easily be identified by checking battery usage by apps and then uninstall it.

Hi

Suspect it could not be an issue of usage of apps or network data or background apps


I just bought it yesterday, connected to laptop to restore a backup , found it getting hot extreme.


Today just now was watching a video and the phone suddenly got very hot as well.


With high processing speed and better battery life as promoted for Iphone 7 compared to Iphone 6,the phone is supposed to handle more process, rather then having a solutions as like clear cache data or close unused apps or use only the data while is required!


Can someone address this issue proper please ?


I am going to visit the apple store today again, feeling irritated to go back and forth after the purchase to understand whats wrong with my new phone.

Jul 31, 2017 6:50 AM in response to Ganapathy_Subramanian

The iPhone has built in temperature sensors that will shut it down if it gets too hot. As long as this doesn't happen the phone is not overheating.


Many activities will cause the phone to get warm. Using the camera is one. Playing video is another. Playing interactive games, especially if they are multi-user and thus using data as well. Charging in general, if the state of charge is below 80%. And charging while doing something else will make it even warmer. Using it for voice or cellular data when the signal strength is weak (1 or 2 dots) requires a lot of energy, and will also cause it to get warm.

If it were a third party application it would have happened before I downloaded the new iPhone OS. My guess is that the new OS was tested on an empty iPhone, so when someone uses a relatively active phone, full of apps of all kinds, the new OS doesn't know how to respond to the added power-draw of the apps, and it overheats. just a guess mind you. When I posted this on FB, people started responding with, 'yes, it happened shortly after downloading the new OS' ...so Bob's your uncle.

Testing was done by over 1 million beta testers over a period of almost half a year, all with different numbers of apps. For example, I have 260 apps on my phone. My battery life is excellent, and my phone doesn't overheat.


And no, if it were a third party app it would not necessarily have happened before you downloaded iOS 11. Consider that there are apps that have conflicts with the new OS. Or that just the update process triggered a bug in the app that was always there but that code path had never been traversed. Apps are "told" when a new version has been installed; they need to do cleanup and possibly adjust settings. But there is no way to verify that this code works before they actually encounter an update.

Me too and I'm so disappointed.. it seems a lot of people have the same issue and Apple doesn't do anything in this regard!

Apple won't do anything about any problems you have unless you let them know. And posting in this forum isn't letting them know. If you have a problem with your phone use the Contact Support link at the top of every page. Better yet, install the Apple Support app on your phone, and you can use it to contact support directly.


However, I'm not sure what your "issue" is. There are several mentioned in this thread. The most common one is the phone gets warm. That is completely natural and expected. It is only an "issue" if it gets so hot that it displays an overtemperature message and shuts down. Does yours do that? If it does, you must contact Apple, because there is a hardware problem with your phone.
