Why Your iPhone Overheats and How to Prevent It

Overheating is a common issue that many iPhone users face. It can be quite alarming when your device becomes too hot to handle, both literally and figuratively. But why does this happen? And more importantly, how can you prevent it? In this comprehensive guide, we will delve into the reasons behind iPhone overheating and provide practical solutions to keep your device cool.

Understanding iPhone Overheating

Overheating can occur for a variety of reasons, ranging from environmental factors to software issues.

Firstly, your iPhone is designed to function in a certain range of temperatures. When exposed to extreme heat or cold, it can start to overheat. This is why you might notice your phone getting hot when you leave it in a car on a sunny day or use it in direct sunlight for an extended period.

Secondly, software issues can also cause your iPhone to overheat. This can happen when an app or the operating system itself is not working properly. For instance, if an app is using too much processing power, it can cause the phone to heat up.

Hardware Issues: Hardware issues can also lead to iPhone overheating. If your device's battery or processor is damaged or faulty, it can cause the phone to heat up. This is often accompanied by other issues like poor battery life or slow performance.

Lastly, charging your iPhone can also cause it to heat up, especially if you're using it while it's charging. This is because charging and using your iPhone at the same time can put a lot of strain on the battery, causing it to heat up.

How to Prevent iPhone Overheating

Now that we understand why an iPhone overheats, let's look at how you can prevent it. Here are some practical tips to keep your iPhone cool.

Keep Your iPhone Out of the Sun: As mentioned earlier, iPhones are not designed to handle extreme temperatures. Therefore, one of the simplest ways to prevent your iPhone from overheating is to keep it out of the sun. Avoid leaving your iPhone in a hot car or using it in direct sunlight for extended periods.

If you're at the beach or pool, keep your iPhone in the shade or inside a bag to protect it from the sun. Also, avoid using your iPhone when it's very cold as this can also cause it to overheat.

Close Unnecessary Apps: If an app is using too much processing power, it can cause your iPhone to overheat. Therefore, it's a good idea to close unnecessary apps when you're not using them. To do this, double-click the Home button (or swipe up from the bottom of the screen on iPhone X and later) and swipe the app windows away.

Also, consider updating your apps regularly as updates often include bug fixes that can prevent overheating. If you notice that a particular app is causing your iPhone to overheat, try uninstalling and reinstalling it.

Update Your iPhone's Software: Software issues can also cause your iPhone to overheat. Therefore, it's important to keep your iPhone's software up to date. To check for updates, go to Settings > General > Software Update. If an update is available, tap Download and Install.

Also, consider resetting your iPhone's settings if it's overheating. This can often fix software issues that are causing the phone to heat up. To do this, go to Settings > General > Reset > Reset All Settings. Note that this will not erase your data, but it will reset your settings.

Take Off Your iPhone's Case: If your iPhone is overheating, consider taking off its case. Some cases can trap heat and cause the phone to overheat. Therefore, removing the case can help the phone cool down.

Also, avoid charging your iPhone while it's in its case as this can also cause it to heat up. Instead, take off the case before you plug in your iPhone.

Let Your iPhone Cool Down: If your iPhone is overheating, one of the best things you can do is let it cool down. Turn it off and leave it in a cool place for a while. Avoid putting it in the fridge or freezer as this can cause condensation to form inside the phone, which can damage it.

Also, avoid using your iPhone while it's charging as this can cause it to heat up. Instead, let it charge undisturbed until it reaches 100%.


Overheating can be a serious issue for iPhone users, but with the right knowledge and precautions, it can be prevented. By understanding why your iPhone overheats and following the tips in this guide, you can keep your device cool and functioning optimally.

Remember, if your iPhone continues to overheat despite following these tips, it's best to contact Apple Support or take your device to an Apple Store for further assistance. It's always better to be safe than sorry when it comes to the health of your device.
