It is alarming to find your new iPhone 13 overheating. It could be that your iPhone 13 feels unusually warm to touch, or hot to touch. Here are ways to cool down an overheating iPhone 13 and steps to take to ensure it remains cool hereafter.

Part I: Why Is iPhone 13 Overheating?

iPhone overheating is an issue for Apple users who, on occasion, have their iPhones uncomfortably warm to touch or even hot to touch. If something similar is occurring with your iPhone 13, your iPhone 13 is overheating. Why does an iPhone overheat? There are several reasons why this could happen, and here is a list of the most common reasons why your iPhone 13 is overheating.

Reason 1: Fast Charging

iPhones used to be mocked for their slow charging when the box used to come with a measly 5W charger. Today, the box comes with no charger, but the new iPhones support fast charging with a 20W or above adapter that you would buy separately. In case you are using the new 20W power adapter from Apple, your iPhone 13 will always fast charge. This can heat the phone up and could be why your iPhone 13 is overheating.

Reason 2: Using While Charging iPhone

If your iPhone is charging and you are performing some heavy activity on the iPhone such as playing a game, this is going to overheat the iPhone quickly. Similarly, video calling is another culprit that overheats a phone quicker than usual when the phone is charging.

Reason 3: Heavy Usage

Heavy usage may comprise using apps that tax the CPU and GPU and consume a lot of power quickly such as games, photo and video editing apps, using the cameras (shooting videos or making video calls) and using apps that are not taxing the system that much but still consuming more than usual power such as apps you use to watch videos, whether downloaded or streamed such as Netflix, Amazon Prime, YouTube, Hulu, etc. Doing any or a combination of any of these together is going to eat the battery soon and falls under heavy usage that can heat the phone anywhere between moderately high to uncomfortably hot depending on the time and kind of usage the phone was under.

Reason 4: Making Calls When Signal Is Poor

You might not think much of it, but if you only have 1 bar of signal and you make long calls or even video calls, this may cause the iPhone 13 to overheat since the radio in the iPhone is having to work quite hard to keep the iPhone connected to the network and is likely operating at greater power than usual.

Reason 5: Using Unoptimized Apps

If you are using apps that have not been optimized to take advantage of the latest software and hardware in the iPhone, this may likely result in overheating iPhone 13 since the old code is more likely to cause issues with the new code, should there be any interoperability and compatibility issues.

Part II: How to Cool Down An Overheating iPhone 13

When you detect that your iPhone 13 is overheating, whether it be unusually warm or uncomfortably hot, it becomes imperative to stop whatever it is you are doing on and with the iPhone and help it cool down. Here are ways you can use to cool down an overheating iPhone 13.

Solution 1: Stop Charging

If your iPhone 13 is charging and you realize it is overheating, just stop charging and take the cable out. This will stop further heating, and the iPhone should start to cool down slowly. To accelerate this process, you may consider switching a fan on so that the phone cools down faster.

Solution 2: Close All Apps On iPhone

Force-close all apps on the overheating iPhone to ensure that apps are not running in the background anymore. To close apps, you need to enter app switcher:

Step 1: Swipe up from the bottom edge of your iPhone but do not leave the screen, instead swipe up until you get a haptic feedback and see the App Switcher.

Step 2: Now, flick the app cards up to close the apps. When the last open app is closed, the app switcher will return to home screen.

Solution 3: Turn Off The iPhone 13

If your iPhone 13 is overheating way too much such that it is uncomfortably hot and closing the apps and not charging it anymore does not seem to help, the next thing you can do is switch it off. Here is how to shut down an iPhone 13:

Step 1: Go to Settings > General > Shut Down

Do not use the device until it cools down.

Solution 4: Take All Protective Cases Off

When dealing with an overheating iPhone 13, it is best to remove all protection cases from the device so that the device is able to radiate all heat out into the environment fully and most efficiently without any hindrances from the protective case you may have been using.

Solution 5: Putting The iPhone In A Cool Place

If you are out under the sun and your iPhone 13 overheats, do not put it in your bag to keep it away from the sun as that will only block ventilation, but instead get away from the sun and let the iPhone cool in a well-ventilated space.

About Trying To Cool Down An Overheating iPhone Rapidly

It might cross your mind to use a refrigerator compartment to cool down the overheating iPhone quickly. After all, what better way to cool it than a blast of chilled air, right? The idea is sound, but the problem here is that the iPhone is hot inside and the chilled air that touches the surface of the overheating iPhone has enough temperature differential to create condensation inside the iPhone and that is not something you want, since that will fall under liquid damage and will void the warranty and might even destroy your iPhone. Avoid this temptation and use the methods described above.

Part III: Side Effects Of Overheating

Overheating is never good for your iPhone. There are bound to be side effects from an overheating iPhone, sometimes noticeable and sometimes not. It depends on how frequently and how much the iPhone overheats. If it was once or twice, it would not cause any permanent damage to anything, but if iPhone 13 overheats several times a day for several days, this is going to have serious consequences for the iPhone.

Side Effect 1: Heat Destroys Battery Capacity And Life

Heat is the enemy of batteries. So, when your iPhone 13 overheats, that heat, depending on how long the batteries in the iPhone were subjected to it, will damage the batteries and you will see a reduced battery capacity and service life.

Side Effect 2: Swollen Batteries

A regularly overheating iPhone 13 is likely going to end up with a swollen battery sooner than later and you will have to get the battery replaced, likely out of pocket.

Side Effect 3: Malformed Chassis

If an overheating iPhone results in a swollen battery, that battery has nowhere else to bulge but upwards, since that is the easiest way out for it. And this means that the display on your iPhone is at risk, and the chassis itself may get bent as iPhones are built to exceedingly tight tolerances and there is next to no wiggle room for anything.

iPhones are built with a lot of thought going in their design, and this includes safety nets that work to help an iPhone not get too warm or hot. Whenever the iPhone detects that the internal temperature of the iPhone is out of its designed operating range, especially when the temperature is on the higher side, it displays a warning to the user and the user can do nothing on the iPhone at this point until the software finds the temperature back within range.

Part IV: Prevent Overheating

With just a few simple precautionary measures, you can ensure that you never have to risk an overheating iPhone. These measures will ensure that your iPhone experience is always optimal.

Measure 1: While Charging The iPhone

Whenever you are charging the phone, avoid using the iPhone. This does not mean to avoid it like the plague, it simply means to limit it as much as possible. If you need to use the phone to make or receive calls, unplug the charging cable and then use the phone. Responding to notifications here and there is fine.

Measure 2: When Choosing Cases For Your iPhone

When you select a case for your iPhone, make sure you buy one from a reputed company and a case that does not interfere with the intended and designed operation of your iPhone in any way.

Measure 3: When Using Apps

When you want to use a heavy app such as a game or a photo/ video editing app, close all other apps. After gaming or editing, close the game or editing app.

Measure 4: Minimize Scanning (Bluetooth, Wi-Fi, etc.)

When you have Bluetooth and/ or Wi-Fi on, the phone constantly scans the neighborhood for something compatible to connect to. When you are not using it, disconnecting the Wi-Fi and Bluetooth can prevent overheating iPhone.

Measure 5: Use Wi-Fi Calling

Just as it is smart to disconnect Bluetooth and Wi-Fi when not using, it is smart to not use your mobile data if your signal reception is poor and switch to Wi-Fi. If you are in a place with poor signal for a long time, such as if your home has poor signal, it pays to enable Wi-Fi Calling on your device so that the phone does not spend power trying to stay connected to the cellular network for everything but connects to the much stronger Wi-Fi signal and consequently use far less power, generating far less heat, and not overheat.

Here is how to enable Wi-Fi Calling if your network supports it:

Step 1: Go to Settings > Phone

enable wifi calling in ios settings

Step 2: Scroll down and under Calls enable Wi-Fi Calling.

Measure 6: About Handling The iPhone

It is one thing to be walking under the sun and using your iPhone and completely another to be leaving an iPhone in a car where the sun is falling directly on the iPhone, the latter can cause the iPhone to overheat. This is even quicker if the windows are rolled up. Whenever the iPhone is in the car, ensure that it is away from direct sunlight and never leave your iPhone in the car.

Using these steps you will ensure that your iPhone does not get uncomfortable warm or hot and overheat.

Conclusion

An overheating iPhone can be scary considering the horror stories available on the internet about exploding smartphones. Therefore, timely steps must be taken to cool down the overheating iPhone 13 and then steps should be taken so that the iPhone doesn't get overheated again.
