Why does my iPhone 12 overheat so regularly?
If your iPhone 12 regularly feels hot to touch and none of the above is the case, your iPhone might have a battery issue, a software issue, or a hardware issue as well. Apart from these reasons, the way you use your iPhone plays a very important role in the overall health of your iPhone. So, let’s have a closer look at each of them.
Battery plays a crucial role in the overall performance of your iPhone. A good battery not only provides you an all-day or a decent usage, but it also helps to improve the overall working of your iPhone.
I would like to share my experience with the same. Last year, when I was using the iPhone 8, I started having several issues with it. My apps were not working properly, sometimes the camera refused to take pictures, and my phone used to get extremely hot at random, even if I wasn’t playing any heavy games. The regular heating and jagged performance forced me into action. I got my iPhone diagnosed at the Apple store and surprisingly, the battery was to be blamed for all the mess. I was expecting anything but the battery for these issues.
After replacing my iPhone battery, I was able to use my phone at a stretch, without causing it to overheat.

Using iPhone while charging
The way you use your iPhone plays a very important role in its health and behavior. You might not pay attention to the way you use your phone until an alarming situation arises.
Here are some of the common reasons that are responsible for overheating your iPhone 12:
- Using your iPhone while charging.
- Streaming high-quality videos for a long period of time.
- Using Augmented Reality apps.
- Playing heavy games for long periods of time.
An iPhone growing warm isn’t a concern, whereas a hot iPhone is an issue. It’s a clear sign of an already faulty device or the one very much at the risk of damage.
Charging and using the iPhone at the same time is a very common thing that we all have done at times. Sometimes we don’t have that patience to keep the phone at the charge, even for a few minutes. And, when you play heavy games while putting your phone on charge, things can go even worse and make your iPhone as hot as lava. Using your phone while charging causes the battery to overheat and can eventually damage it. In order to avoid overheating your iPhone and putting it at the risk of damage, make sure you never do the listed things, beyond a normal point.
The CPU of your iPhone is a powerful chip, which is responsible for the overall performance of your iPhone. And, just like the computers, the CPU of your iPhone heats up the fastest. But, having compared the iPhone with a computer and using it the same way to get your job done, we cannot deny the fact that the iPhone tends to overheat when used for long hours. And, this is quite natural for any smartphone, that’s been under stress for a long time. This happens due to the fact that unlike the computers, your iPhone doesn’t have a heat sink or a fan to regulate its temperature and keep everything cool.
The CPU of your iPhone is so powerful that it rarely uses 5% of its capacity. Your iPhone remains nice and cool under such scenarios. But, there are certain apps that are capable of gearing the CPU of your iPhone all the way up to 100%. As a result, your iPhone gets overheated. Now, we need to find the app that’s not working properly and put a stop to it. We’ve mentioned all the necessary steps in the next section.
