Causes and ways to fix iPhone overheating

When iPhone gets hotperformance will be reduced and the battery will age faster. Below are the causes and How to cool down a hot iPhone.

What causes iPhone to get hot?

• High intensity use: Performing power-intensive tasks (like playing games) for long periods of time can put a lot of strain on the processor and internal components. This increased workload can generate significant amounts of heat.
  
• High ambient temperature: Exposing iPhone to high temperatures or direct sunlight for long periods of time can cause the device to overheat more quickly.
  
• Software problems: Software errors, system errors (bugs) or compatibility issues in iOS or third-party applications sometimes cause the iPhone’s processor to work harder than necessary, leading to overheating.
  
• Hardware problem: Defective components—such as a damaged battery or malfunctioning charging cable—are another major cause of overheating. Any damaged or malfunctioning components can easily disrupt your iPhone’s natural cooling mechanism.
  
• Charge and use at the same time: Continuous use of iPhone while it is plugged in can cause overheating.
  
• Poor heat dissipation: Thick, bulky cases or screen protectors that are too thick can hinder the iPhone’s heat dissipation process, leading to the device overheating.

How to cool a hot iPhone

Avoid high temperature environments

Apple recommends that users use iPhone between 32º and 95º F (0º and 35º C). However, in most tropical regions, actual temperatures are often much higher than this.

Of course, you don’t have to stop using or buying an iPhone in these areas. However, if you have used the device in a hot environment for a long time, please stop using the device after a long period of time.

In addition, absolutely do not leave your iPhone in a parked car, because the temperature inside the car can increase very quickly and high. This is a potential safety risk!

Discard the defective charger

One of the first things to do when your iPhone keeps getting hot is to check the charger. If you are using a defective charger, discard it immediately!

Although there are many iPhone chargers on the market, only a few meet MFi standards and fully support the device. Poor quality chargers are not only incompatible but also unsafe and can cause damage to your phone.

Note:

Make sure the Lightning port or Type-C port (on iPhone 15 and later) is always clean, free of dirt or lint. Accumulated dirt or debris can interfere with the charging process, leading to overheating.

Remove the back cover

Although using the iPhone without a protective case is not recommended, you can completely remove the case if the device overheats.

When the iPhone is in a case, heat emitted from internal components (such as the processor and battery) will be trapped inside the device. This causes the temperature to rise and leads to overheating.

Removing the case helps heat escape more easily, preventing heat buildup that can harm the iPhone.

Free up storage space on iPhone

An iPhone containing too much data often encounters many problems such as slow performance and constant overheating. If you haven’t cleaned your iPhone in a while, it’s likely that the memory is being taken up by large files, affecting the device’s performance.

In this case, find and delete redundant files, old iCloud backups that are no longer needed, uninstall outdated apps, and get rid of any unused screenshots, images, and videos to free up storage space on your iPhone. You can use some apps to free up iPhone space like GOM Saver for iOS.

Restart your iPhone

iPhone, like many other electronic devices, works better if it is restarted regularly. So try restarting your device.

If the above methods do not work, restarting the iPhone can help completely solve the problem of overheating.

Turn on Low Power Mode (Low Power Mode)

This mode is designed to reduce power consumption by turning off some battery-draining features, such as automatic downloading and email fetching.

Thanks to significantly reduced power consumption, the battery won’t have to work as hard, which plays an important role in keeping iPhone cool even during continuous use.

Enter Settings → Battery → enable Low Power Mode.
