How and why to keep your iOS device from overheating

Just yesterday we told you about the most common problems that an iOS device camera could have, among which there was one related to the device overheating, which made the flash not work . Well, today we will explain what happens when the device gets too hot and what conditions cause this situation.

As you may know, iOS devices do not have built-in internal fans to cool the components , so instead, the operating system is programmed to regulate the heat itself through performance reduction.

There are many reasons why an iOS device can get too hot . As mentioned, you do not have fans inside your devices due to their extreme thinness. Instead, it is up to the hardware to perform this function by using a chip, the battery and other components to regulate the temperature of the device.

Normally, the actions that can cause your iPhone, iPad or iPod to overheat are

  • Leave the device inside a car when there are high temperatures outside.
  • Expose the device directly to the sun for too long.
  • Perform actions that require the intensive use of hardware such as a game or the use of GPS
  • Constant changes in coverage.
  • Any combination of the above actions.

An iOS device should never reach a temperature of -17°C or higher . Similarly, it should not be stored in places that have a temperature lower than -20°C or temperatures higher than 45°C. Doing so may result in reduced performance or even damage to those handling the device.

What happens when an iOS device overheats?

Having explained how to prevent your device from getting too hot, let’s comment on what would happen if this were inevitable .

When a device becomes overheated, the hardware of the device starts to regulate its temperature , decreasing the work done by the terminal and even becoming disabled until it recovers normal temperature values. This “safety” mode can have the following measures:

  • The battery does not charge to prevent excessive heat generation.
  • The screen may become less bright or turn off completely, making it almost impossible to use the device.
  • While using the device, the display will show an alert and then turn off.
  • Wireless systems will go into power-saving mode so they may stop working.
  • The LED flash will stop working until the device cools down.

These measures may vary depending on the severity of the terminal overheating. It is normal for an iPhone to heat up when it is in continuous use or is charging , but we must avoid going to the extremes mentioned above, to avoid creating damage to our devices.

How to avoid overheating

To prevent our device from overheating we will take as a guide the previous section “Why do iOS devices overheat?

  • If you’re going on a road trip, and it’s a hot day, put your device somewhere cool and shady, like under the seat. Avoid putting it on the dashboard or in the glove compartment.
  • Avoid leaving it directly in the sun for a long time.
  • If in your case, it’s more likely to get hot from hardware uses such as gaming or GPS use, try giving it a rest every few months or decrease the screen brightness.
  • Avoid using the device while it is being charged.


Devices should not be overheated, as they could become damaged . Similarly, in extreme situations, it may be dangerous for the user, with the battery swelling or even exploding – this is not very common but there have been cases – so it is advisable to take care of this aspect.

In the event that the device becomes excessively hot, the best thing to do is to turn the device off and place it in a cool place for a few minutes to return it to its normal temperature. A few simple but very useful tips, which you will want to remember if you find yourself in a similar situation.
