Check out the core of the video article below:

A new update has been added at the end of this story …

The original story (published November 19, 2020) is as follows:

Apple first released the iPhone 12 and 12 Pro on October 23, and a few weeks later the iPhone 12 Pro Max. And many reports on the problem of overheating of all three devices have already begun to flow.

There are some complaints listed on the official Apple forums and Reddit about the same thing.


My iPhone 12 Pro gets significantly warmer with very light use. No, not when you’re not connected. Refers to normal use when not connected to a charger. I turned off 5G and still do this. The moment you start using it, your fingers are warming from the center left of the phone. By comparison, the right side is cool to the touch. Again, this is a very light usage. I’m using the latest version of iOS. I had an 11 Pro before this and I didn’t have this problem.Source

Yes, I had the same problem. It doesn’t overheat during phone setup or charging, but when playing basic games on fios WiFi, the phone, especially the metal rim, heats up very quickly and is difficult to hold without a case. did. My 11 pro was fine, so it’s not good at all.Source

This issue seems to be primarily related to the iPhone 12 Pro, but there are exceptions. Some users are also complaining about the overheating issue on the iPhone 12 and even the recently released iPhone 12 Pro Max.

Therefore, this problem seems to be spreading throughout the lineup. However, it is important to note that these reports make up only a small part of the overall unit, as device reviews are mostly positive.

Nevertheless, there are too many reports to overlook. The problem was initially related to the fact that the device was new and it took a long time for the phone to settle down after initial setup and data transfer.

Since then, complaints have been flooding. Some users have also stated that they are now far past the setup stage, but the heating problem still persists.

A deep dive into this issue revealed that it was not possible to narrow it down to a single criminal. Users are facing overheating in various scenarios.

Some say it only occurs during charging. Others say during Face Timing and games. However, many others have stated that they also face it when performing normal tasks such as browsing.

Anyway, if you are one of the users facing this issue, don’t worry. We have compiled a list of possible causes and a workaround for each. Try what you think is most appropriate.

Or you can just try them all and look afraid that your phone will slowly turn into an expensive ice slab (just kidding).

Possible causes and workarounds for iPhone 12 overheating problem

Apple iPhone 12 Pro Max

1. Overheating during and after initial setup: Several users have reported that the new iPhone 12 appears to be overheating during the initial setup and data transfer phase.

If you are one of such users, this behavior is fairly normal and you may sigh of relief. By default, any phone can consume a great deal of resources and can be expected to have some heating.

Wait for the device to settle for at least 48 hours before checking again. If the problem persists, proceed to the next set of workarounds.

2. Abnormal usage app:

1. Check the iPhone battery settings for background apps that are being used abnormally. Such apps run in the background and can put unnecessary load on the cell phone’s processor.

[設定]>[一般]>[バックグラウンドアプリの更新]You can also go to and turn off apps you don’t want to run in the background.

2. Another notable point here is that many users are tracking overheating of the Waze app. They say uninstalling it helped improve battery life and alleviate the problem.

My 12 pros were also hot. I went to Settings, Battery and found Waze on in the background for hours. I went to Settings, General, Background App Updates and turned it off, but it seems to be running better now. Check if the app is running in the background. I think Waze and other apps will be updated for this IOS.Source

3. Alternatively, you can disable iPhone analysis. To do the same[設定]>[プライバシー]Go to. Then scroll down to “Analytics” and disable “Share iPhone Analytics”.

4. You can also try limiting access to your location to apps that you don’t think you need it. is this,[設定]>[プライバシー]>[位置情報サービス]You can do it from. Then select the app and turn the “Exact Location” switch on or off as needed.

Apple MagSafe Charger for iPhone

3. Charging: Some users have faced overheating while charging, both wirelessly and with cable.

I pre-ordered my iPhone 12. It got a little warm during setup. However, it gets very hot during charging and I don’t have a wireless charger. I was using the same charger that I used on my previous iPhone 11. When I removed the phone from the charger, it was charged for about an hour. When I went to pick it up, it was so hot that I could hardly touch it. it.Source

If you are facing the same issues as the above users, the charger may be defective. Use an officially supported charger.

Also, try charging in a cool environment. You’ll be amazed at how hot your device can be if you leave it charged in direct sunlight. It is best to avoid such places.

4. Poor network reception: Poor cell reception can also act as a catalyst for heating problems, as it makes it much more difficult for the device to find a reliable signal.

In addition, Apple’s iPhone 12 lineup seems to include Qualcomm’s Snapdragon X55 modem. This is an external modem that consumes more power and in some cases produces more heat.

When it comes to receiving cells, you can’t do much other than walk to the nearest 5G tower. This is clearly not feasible. But hey, at least you know why your phone gets hot when you have a poor signal.

5. Unit Failure: If you have tried all of the above and the device continues to warm abnormally, the unit may be defective. Replacing it will definitely solve the problem.

That said, let us know in the comments below if the above workaround fixed the iPhone 12 overheating issue.

Also, check out our dedicated iOS 14 bug tracker for more information on these issues.

Update 1 (January 21, 2021)

18:24 pm (IST): Yeah, this is embarrassing. This issue seems to have occurred through various new updates, including the recently released iOS 14.3, and simply refused to disappear.

This is due to some new comments about existing threads. Apple needs to seriously pull up its socks to resolve this issue as soon as possible!

Update 2 (March 5, 2021)

16:24 pm (IST): According to the report, the heating problem continues after iOS 14.4. Surprisingly, visitors to the Genius bar were told that the heating bit was normal for the new chipset. Here’s what the affected users shared:

Like Apple, overheating devices is normal for new chipsets and does not accept product defects, so have a bitter experience from them.

They simply restored the software and returned the product.

The device remains in the same state as before.

After using the camera for 15 minutes, it heats up to over 42.9 cm, which makes it very difficult to hold the device.

According to Apple’s genius service staff, the solution is to hold the phone during overheating, and when they say it’s difficult to hold the phone during overheating, they are suggested to buy an Apple Silicone case from them. I did. (It’s like using a glow to remove a hot utensil from the microwave)

Update 3 (March 12, 2021)

17:45 pm (IST): Well, in this case, it became clear that even the replaced units somehow suffered from the same problem. Let’s take a look at what users have recently shared.

Also, if you don’t want to get hot in most cases, you should put it in low power mode. I took it to the Genius Bar and they were trying to replace everything except the screen and camera. I went to pick it up yesterday, and they said there was a problem, and they eventually replaced the phone. I recovered yesterday afternoon and, as always, when I woke up this morning, it was really hot within 10-15 minutes. These photos are from this morning.This is normal if you are not in low power mode

Update 4 (March 19, 2021)

12:45 pm (IST): During all these months, various community specialists redirect affected users to clarify why the unit is being heated by the official “allowable operating temperature”. Please note that we are checking (here).

Update 5 (March 20, 2021)

16:30 pm (IST): Using the one shared by one of the readers who has disabled “Optimized Battery Charging” may work. Therefore, you can also try this workaround.

See Optimized Battery Charging. Try this:

[設定]>[バッテリー]>[バッテリーの状態]>[最適化されたバッテリー充電]Go to. power off.

Update 6 (April 4, 2021)

01:00 pm (IST): Another workaround is to reduce the brightness of the device if it has been set above 50% for a long period of time. This may be one of the reasons the unit is overheating.

Update 7 (April 8, 2021)

02:00 pm (IST): Find an app that consumes battery on your device as it consumes a lot of CPU and can cause your device to heat up.

To do this[設定]>[バッテリー]Go to and look for apps that are consuming excessively high battery. Uninstall the app and test if this process helps reduce device heating.
