Here are tried and tested 4 ways to cool down an overheated iPhone 13 quickly.

Method 1: Place It Next to A Fan

Placing an overheated iPhone 13 in a refrigerator compartment can sound like a great idea in theory, but practically that does not go well for the iPhone and there are chances of condensation. By far the fastest method to cool down an overheated iPhone 13 is to place the iPhone 13 next to a fan or under a fan to bring down the temperature quickly.

Method 2: Stop Charging

If the iPhone 13 is overheated and you want to cool it down quickly, you should stop charging it. Charging the iPhone heats the iPhone and if you stop this heat source, the phone will start to cool down. When the temperature is back to normal, you may resume charging if needed.

Method 3: Turn iPhone 13 Off

One of the fastest ways to cool down the iPhone 13 is to shut it off to bring all electrical activity to a minimum. When the phone feels like room temperature or below, you can start it again. Here's how to shut down an iPhone 13 to cool it down:

Step 1: Go to Settings > General and tap Shut Down

Step 2: Drag the slider all the way to the right.

Method 4: Remove All Cases

If the iPhone is overheated and has any case on it or is inside a sleeve, remove it and place it in a well-ventilated area so that heat can escape, and the phone temperature can return to normal levels.

If after doing all of the above, your iPhone 13 does not turn on, and you are certain you are not seeing the temperature screen on the iPhone, there are steps you can take to switch the phone back on.

Part II: What to Do If iPhone Does Not Turn On

If an overheated iPhone 13 does not turn on even after it is cool to the touch once again, there are things you can do to try and turn the overheated iPhone 13 back on.

1. Check Battery Charging

An overheated iPhone 13 may have depleted the battery. Connect it to power and wait for a few seconds to see if the phone boots up.

2. Hard Restart

Sometimes a hard restart is what you need to get an overheated iPhone 13 back to life. Here's how to hard restart your iPhone 13:

Step 1: Press the Volume Up button once

Step 2: Now press the Volume Down button once

Step 3: Quickly press the Side Button and hold it until you see the phone restart and the Apple logo appears.

3. Use A Different Charging Cable

Your iPhone 13 might have overheated due to a charging cable issue as well. Once it has cooled down, use a different charging cable, preferably a genuine Apple charging cable, and connect it to the phone and see if the phone charges properly and boots up.

4. Use A Different Power Adapter

After the cable, you should also try a different power adapter. It is recommended to use Apple-approved adapters only to get optimal and reliable performance with minimum chances of issues.

5. Clean The Charging Port

It is possible that there is dirt in the charging port on your iPhone, which may have led to the initial overheating of your device as well. Look inside the port with help of a flashlight for any debris or lint inside that might be hampering a proper connection. Remove with a pair of tweezers and charge again - the issue would likely be resolved.

6. Check For Dead Display

It is entirely plausible that the extreme overheating iPhone took down the display and the rest of the device is working. How to check that? Ring your iPhone from another line. If it works, it means your display is gone and you need to take it to the service center for repair.

If it isn't a dead display, if it isn't a bad cable or adapter and your overheated iPhone still isn't powering on, it is time to check for software issues. Apple does not give you any way to do that, all you can do with Apple is to connect and restore the firmware or update the firmware. But, there are third-party tools such as Dr.Fone - System Repair (iOS) that help you with the better diagnosis of the issue because they work in the language you understand rather than the language of error codes.

Part III: Useful iPhone 13 Maintenance Tips

Now that you have successfully powered your iPhone, you might be wondering if there is anything you can do to prevent such situations in future. In other words, you are looking for useful iPhone 13 maintenance tips that keep your new iPhone running like new. Yes, there are some steps you can take that ensure your iPhone 13 runs as smoothly as it can with minimal issues of overheating and other such annoyances.

Tip 1: When Charging

While charging the iPhone, use it minimally so that it not only charges quicker but also cooler. On topic, use fast-charging solutions when travelling or in areas with adequate ventilation so that the heat generated with faster charging (higher voltage) may be dissipated into the environment seamlessly, keeping the temperature of the iPhone within spec.

Tip 2: About Cables And Adapters

Apple's products are more expensive than the competition, and this goes for all of their products, right down to the comically expensive 6 in. x 6 in. Polishing Cloth that Apple sells for USD 19. However, when it comes to charging, it is advisable to use only Apple's own chargers and cables. It pays in the long run because these are not going to harm your device in any way whatsoever as any others might.

Tip 3: Screen Brightness

This may seem odd, but yes, if you use high brightness levels, not only is this damaging to your eyesight, it is also damaging to the iPhone as this does cause the phone to consume more power and consequently, heat up more than it would otherwise if used on a lower brightness setting.

Tip 4: Cellular Reception

Unless it is a substantial financial hit, you should switch to a network that gives you better signal not just because a better network gives better upload and download speeds and usage experience, but a more robust signal is also beneficial to the iPhone battery since the radio has to work less to maintain requisite signal power.

Tip 5: Keeping Apps Updated

Old apps that are no longer maintained or available may be available to download in your App Store purchase history, but they are best avoided when it's been long. Software and hardware are different now than back then, and incompatibilities might make the iPhone overheat and cause issues. It is best advised to keep your apps updated and look for alternatives to the ones that are no longer receiving timely updates.

Conclusion

Knowing how to cool down an overheated iPhone 13 quickly is of paramount importance since heat can damage the batteries inside and create new issues for you to deal with now or later. Regular overheating can manifest outwardly as swollen batteries that are going to show up on your iPhone as bent exterior or a display that popped out. If your iPhone is overheating, cool it down quickly and the fastest way to do it is not the refrigerator - it is placing it next to a table fan or under a ceiling fan at full speed. If the iPhone 13 does not turn on after cooling down, you can use Dr.Fone - System Repair (iOS) to fix any system issues that might be preventing the iPhone from starting up.
