Why is my iPhone Overheating? Explore the causes, symptoms, and solutions

Have you ever experienced your iPhone feeling hot to the touch, the battery draining quickly, and the device slowing down while using various apps? 

Overheating can affect the performance of your device, reducing its efficiency and causing other problems. If you leave it unattended, your device can face serious consequences, such as battery explosions.

In this article, we'll delve into why your iPhone is overheating and what you can do to fix this issue. So, let's get right into it.

Why is my iPhone Overheating?

As an iPhone user, you expect your device to work smoothly and efficiently at all times. Yet, sometimes you may notice that your iPhone overheats for no reason. This causes the battery to drain faster, compromise the performance of the phone, and even results in severe damage.

So, what could be causing your iPhone to overheat? Let's take a look at some of the reasons:

  • Running too many apps or processor-intensive programs at once.
  • Exposure to high temperatures (direct sunlight).
  • Pending software updates or corrupted software.
  • Using a third-party charger to charge an iPhone. 
  • Low memory or storage space.

How to Stop an iPhone from Overheating?

To stop your iPhone from any damage, address the overheating problem by following the solution mentioned below. 

Force Quit All Apps

Reducing the processor's workload can stop your iPhone from overheating and draining the battery. To do this, force quit all or resource-hungry extensive apps with these steps:

  • Swipe up on your iPhone's home screen and stop in the middle to launch the App Switcher.
  • Tap and swipe up all app previews one by one to force-close them.
  • Alternatively, swipe right or left, find an app that you think is draining the phone resources, and swipe up its preview to force-close it.  

Restart Your iPhone

Restarting your iPhone can free up occupied memory and clear temporary files that can potentially fix the frequent overheating issues. 

  • Press and hold the "Power/Side" and "Volume Up/Down" buttons until the power off slider appears.
  • Drag the slider to power off your iPhone and let it cool down completely.
  • Now, press the "Power" button to restart your iPhone, use it for some time, and see if this fixes the issue.

  • Go back and tap "Privacy."

iPhone Overheating and Won't Turn On

It can be frustrating and nerve-wracking if your iPhone is overheating, shuts off by itself, and won't turn on. With the following quick hacks, you can start using your device again in no time.

It is also possible that your charging cable or adapter is old and damaged, providing more or less power than what your iPhone is designed to handle. This can cause overheating, battery drainage, and intermittent shut-off issues on your iPhone.

In such cases, it is advisable to use a genuine Apple charging cable or adapter to avoid further damage to the phone.

Hard Reset the iPhone

To get your iPhone back to life, you can also try hard resetting it in the following way:

  • Press & release the "Volume Up" button.
  • Next, press & release the "Volume Down" button.
  • Finally, press & hold the "Side" button until your device restarts and the Apple logo appears on the screen.

Check the iPhone For Dead Display

Extreme overheating can cause your iPhone display to become dead or not work at all. To check this, try calling your phone from another one to see if it's ringing.

If yes, take your iPhone to a repair shop to replace the display. Before taking your device to the repair store, it's better to check iPhone repair costs in advance so that you can assure that prices are afforable.

iPhone overheating for no reason

If you believe your iPhone is overheating for no reason, this might not be true. Some factors at play can make your mini-gadget too hot to touch, such as:

  • You’ve left your iPhone out in the sun for too long.
  • You are using your iPhone in a room with high ambient temperatures.
  • You are keeping your iPhone screen awake for too long.
  • The protective case is blocking the adequate airflow needed for the phone to work optimally.
  • The brightness is not set to automatic adjustment, causing the phone to display a bright screen all the time and get hot.
  • Too many apps are active at a time.

We’ve compiled a few fixes to stop your iPhone from overheating for no reason. Let’s briefly look at all of them and explore which one will work best in your favor.

Adjust Ambient Temperature

You may have been using or left your iPhone in a room or area with high ambient temperatures. Apple recommends storing or using your iPhone where the ambient temperature does not exceed 45º C or 113º F.

These areas can be a hot room in the summer season, a kitchen while cooking your food, or a car with windows closed.

So try to avoid storing your iPhone in these areas, especially don’t leave it under your pillow while sleeping, as this will gradually heat up the phone and cause malfunction. 

Note: Do not place your iPhone in a bag with other devices because the hot air out of them will have nowhere to escape, resulting in your device overheating.

Place iPhone in Shade

Using or placing iPhone in direct sunlight can cause it to overheat for no reason. So, attend your calls, browse the internet, or place your iPhone for a more extended period in a bit of a shade.

QUICK TIP: Avoid charging your iPhone when it is too hot to touch. 

Change Brightness Settings

Your iPhone automatically adjusts brightness according to the environmental condition. However, you may have accidentally turned off this feature, and your phone is always running on the brightest settings, resulting in overheating. 

To fix this issue, turn on the Auto-brightness settings on your iPhone with these steps:

  • Open “Settings.”
  • Tap “Accessibility.”
  • Tap “Display & Text Size.”
  • Toggle on “Auto-Brightness.”

You can also try enabling the Low Power mode on your iPhone to keep the screen awake for shorter intervals, which will help cool it down.

Remove Protective Casing

Your iPhone protective casing might be blocking the air and is the culprit for the overheating issue. So try using your phone without it and check overheating issues. If your iPhone functions normally afterward, use it without the case while using it for long hours. 

You should also try cutting down on the streaming time because constant uptime can cause the iPhone screen to overheat.
