There are several warning indications you’ll notice if your iPhone becomes too hot. It will be warm to the touch, but you might also notice that it’s operating more slowly, that the screen has turned dark, that it won’t charge, or that the camera won’t take images.
If the heat is extremely intense, you can even get a splash screen with a temperature warning. You can only make emergency calls while this warning shows until your phone has cooled down.
If you keep your iPhone running hot for too long, heat can harm internal components, especially the battery and processor. Here’s how to avoid your iPhone heating up.
My iPhone becomes heated, why?
It’s likely that your iPhone will become warm if you leave it in the car or in direct sunlight when it’s hot outside.
It may also occur if your iPhone is performing other processor-heavy tasks, like as gaming, streaming HD video, or utilising GPS navigation, or if it has too many open apps.
How to stop your iPhone from overheating
The easiest approach to prevent harm to your iPhone’s internal components when you discover it has become too hot is to take prompt action.
1. Exit every app
By reducing the processor’s workload, you can stop the battery from being drained too quickly and the processor from overheating. Therefore, the first action you should take is to close all apps.
2. Restart your iPhone
Simply restarting your iPhone will force all open apps to close themselves if you don’t have the time or patience to do so. Your iPhone can be restarted in a variety of ways.
To restart an iPhone X or later:
1. Hold down the Power button and either of the Volume buttons for a few seconds.
2. A slider will appear at the top, telling you to slide to power off. Press the power icon in the slider and drag it to the right.
3. Let the iPhone cool down for a few minutes.
4. Hold down the Power button for a few seconds and release it when you see the Apple logo on the screen.
To restart an iPhone SE, iPhone 8, or earlier:
1. Hold down the Power button for a few seconds.
2. When the slide to power off slider appears at the top, press and drag the power icon inside it to the right.
3. Wait a few minutes to give the iPhone time to cool down.
4. Press and hold the Power button and release it when the Apple logo appears.
3. Switch to an official Apple charger
Some chargers from other brands cost less than those made by Apple. But that’s because the charger wasn’t specifically designed to supply the necessary quantity of electricity. It could be overtaxing your gadget. Here, changing that out for an Apple charger might be beneficial.
4. Use Airplane Mode
Your computer’s overheating problem can be caused by the fact that it is always connected to the internet. If so, activating aeroplane mode can assist you in getting around it.
5. Turn Off Background Refresh
Apps that you aren’t actively using but haven’t yet closed out can check for updates and new content utilising Apple’s Background Refresh function.
The overheating problem may be caused by these background activities. Go to Settings on your iPhone, select General, then Background App Refresh to disable it. At the top of that page, tap the feature’s name once more, and then select Off.
6. Update Your iPhone
Maintaining the most recent version of iOS is important since it includes speed enhancements that can stop your phone from overheating.
In order to remove patches for problems that can result in performance issues and processor overload, you need to update your apps as well.
7. Limit Processor-Intensive Tasks
Limiting a difficult task, like playing 3D games, if you see that it causes your phone to become overheated.
Use a PC or game console instead if there are other nearby devices that can do the same function to avoid overheating your phone.
8. Turn On Auto-Brightness
Your battery life may suffer and your phone may become hot if your brightness is set too high.
Fortunately, the iPhone features an option that automatically changes the brightness according to the lighting conditions outside.
Here’s how to turn it on.
1. Open the Settings app.
2. Scroll down and tap on Accessibility.
3. Under the “VISION” heading, tap Display & Text Size.
4. Scroll all the way to the bottom and switch the toggle for Auto-Brightness
9. Try Using Low Power Mode
More heat is produced by your phone and more battery life is lost the longer your screen is on.
By turning on Low Power Mode, you can shorten the time your screen is awake.
1. Open the Settings app.
2. Scroll down and tap on Battery.
3. Switch the toggle for Low Power Mode at the top.
10. Scan For Apps Causing Overheating
Your iPhone may occasionally have problems caused by a certain app, such as overheating and even crashes.
If you have a suspicion that this is the case, you can verify it by heading to Settings and choosing Privacy. Select Analytics Data after tapping Analytics & Improvements. You will see a list of any apps that have crashed by doing this.
11. Stop Charging It Immediately
Unplug your iPhone as soon as it starts to grow too warm when charging. Your phone may get a little warm while charging, but you should disconnect it if it feels hot to the touch.
12. Keep Your iPhone In Cool Places
It should go without saying that you should never leave your iPhone in direct sunlight. And if it starts to get hot inside the car, roll down the windows, switch on the air conditioning, or park in a shaded area to keep the temperature down.
Additionally, avoid placing your phone under your pillow while you are sleeping, especially if it is charging, as the cushion will prevent heat from exiting the device.
To prevent heat exchange, you may wish to keep the phone away from other heat-generating equipment as well. Make sure they are turned off if your iPhone must be in close proximity to them.
13. Remove It From The Heat Source
Remove the iPhone as soon as possible to prevent the internal temperature from continuing to rise, regardless of whether you left it in direct sunshine or a warm car.
14. Take Off The Case And Fan The Phone
Remove your iPhone from its case while it is cooling down to improve airflow. The case can trap heat and slow down the cooling process.
While you’re at it, store your iPhone somewhere cool or use a fan to help it dissipate heat more quickly.
15. Reset Your iPhone
After attempting the aforementioned methods and your iPhone is still overheating, you should reset the device to its factory default settings.
This will remove all installed apps and personalised settings, however, it might aid in identifying the cause of the overheating.
16. Get Your iPhone Repaired
The last recourse after trying all of the measures above and your iPhone is still overheating is to send it in for repairs. You might have a hardware issue that needs to be fixed by a professional opening up your phone.
To arrange an appointment at your nearby Genius Bar, the best course of action is to ask Apple support for help.
