Why is my S7 Running Hot?

Why is my S7 Running Hot?

| On 17, May 2016

There have been concerns from Galaxy S7 and S7 Edge users about their phones running too hot. The cases of this aren’t isolated, but the question is whether this is to be expected or whether it’s cause for concern.

Well the short answer is that it depends on what is causing your S7 to run hot. It could be that your S7 is defective and needs to be replaced, or it could be nothing to worry about and side effect of using a particular function or app.

Why is my S7 running hot? Could be your processor

Some have suggested that the cause of these flagship phones running hot is the processor that Samsung have used in the Galaxy S7.

For the release of the Galaxy S6, Samsung made the decision to abandon the Qualcomm processor it had been using for in its previous models in favour of a completely new processor. This was thought to be in an attempt to prevent the S6 from overheating – a problem plaguing previous models.

It probably came as a surprise for some when Samsung abandoned the processor used in the S6, and reverted to back to the Qualcomm processor for the S7 and S7 Edge. This has again raised questions of problems with over heating for the S7 range.

However, in both the Galaxy S7 and the S7 Edge, Samsung have included a liquid cooling system, designed specifically to combat its problems with overheating components.

Why is my S7 running hot? Could be high intensity usage

Android Authority recently ran tests to see whether the S7’s cooling system actually worked and whether overheating was an issue with the S7 and the S7 Edge.

What they found was that when using the S7 and S7 Edge for purposes that put a high amount of stress on the processor and components, such as 4K video recording and 1080p recording, both models saw a significant rise in heat levels.

However, when used for typical functions or “resource intensive tasks,” such as gaming, there was far less heat emitted from both devices.

So one conclusion for why your S7 is running hot, is that you’re using it for high-intensity camera usage. While the overheating is not a problem for performance or a hazard to the phone itself, it is clear that the both the S7 and the S7 Edge do produce higher amounts of heat when used this way.

In all, the Galaxy S7 Edge runs slightly cooler than the S7, primarily due to having a larger surface area for heat to escape.

How can I stop my S7 from overheating?

So while slight overheating can be expected when performing certain tasks and while operating particular apps, in general your S7 shouldn’t be running at a high heat. However if it is, there are some tricks you can use to try to handle this.

The first is to make sure you don’t jump to conclusions too quickly – it’s normal for a phone to run hot the first few days of usage because you’re downloading apps at a higher rate than usual, which will cause the S7 to get hot.

The best thing to do is wait a couple days before judging whether your S7 is actually overheating.

Another reason why your S7 could be overheating is if you’re using it while you’re charging your phone. The best thing to do to avoid this is simply to refrain from using your phone while it’s plugged in.

If you want, you can also mitigate this issue by going to Settings > Battery and then turn fast Fast cable charging to off.

Another possibility could be that a particular app is causing your S7 to overheat.

Figuring out which app could be the cause is more tricky, but a general solution would be to go to Settings > Battery > Battery usage > More > Optimize battery usage and then choose All apps – what this will do is make sure that your apps opened in the background aren’t draining your battery even while they aren’t being used, because this will cause your S7 to heat up.

If nothing else seems to be working, and you need to get to the bottom of the problem – whether it be a particular app or simply a faulty device. Then go ahead as a last resort and wipe your S7.

Go to Settings > Personal > Backup and reset > Factory data reset > Reset device, you’ll then need to enter your PIN and select Delete all. Be sure to back up your phone first, as this will wipe your entire device, restoring it to factory settings.

Before  syncing your old settings or downloading anything, go ahead and see if your S7 is still overheating, even with just the factory settings. If it is, then the only thing left to do is contact Samsung and request a new device.

    I have a tip. Get an iphone. I got switched by an employer a couple of years ago and I hated it for about 6 months because I wanted to hate it, because thats what Android users do. but now my 2 year old iphone still works great and is trouble free. My wife that insists on staying on Android, is having issues with her new S7. It is overheating, and so when you look for a solution, you start seeing that you might try these 10-20 steps and we hope it works kind of solutions. It is a lot of work to run an android phone. I suggest you get over yourselves and just try an iphone for a year, you won’t go back either. This overheating issue just might get her to finally switch to an iphone and it will free up a lot of my time troubleshooting the crappy Android systems. Face it, it just isn’t as good as iphone. Oh I know all the benchmark tests and specification wars, but I have actual side by side proof that Apple knows how to build a great useful product and Samsung and Google don’t.

      Forgot your history? Apple has had their share of overheating phones.

    I too have tried all the S7 solutions and it still runs very hot. When it is hot it won’t work properly, either. The touch screen won’t work, for example. I am hoping it will fail totally as the seller does not want to exchange the phone (“We’ll have to send it back to Samsung and let you know in 10 days”). If the battery catches fire I figure I will then be given a new phone.
