If the smartphone is too hot in midsummer, there is a risk of malfunction or long-term damage. Although there are not many cases in which a smartphone explodes or burns itself, even in this case, the heating of the smartphone is a typical symptom such as a malfunction of the battery.

It’s unlikely that iPhones will explode, but if you can find the cause of the overheating problem and fix it early, it’ll be good for your mental health. With heat waves observed across Europe and Asia in the aftermath of the climate crisis, here are 11 ways to deal with your iPhone getting hot.

How to keep iPhone temperature cool

If your iPhone overheats for no reason, check again how and where to use it.

  1. Remove the case. If you put a single layer of insulation on the outside, it becomes difficult to cool the smartphone. A cooling case and a cooling case are also sold. Cases with vents may be considered. Some people add cooling fans to their iPhones.
  2. Never leave your iPhone in your car on a midsummer day. The indoor temperature rises rapidly. 
  3. Avoid direct sunlight. You have to be especially careful during the summer holidays. If you’re traveling to a sunlit vacation spot, you should keep your iPhone in the shade or in a bag that blocks out light. The time spent using the iPhone should be reduced as much as possible.
  4. Reduce your game play time. The latest mobile games with great graphics overheat the processor, causing the device to overheat.
  5. Try disabling Bluetooth settings, which can also cause heat. Turn off Bluetooth in the Settings Center or swipe down from the top of your iPhone screen and tap the Bluetooth icon. If your iPhone has a home button, swipe up from the bottom.
  6. Turn off location services. GPS also generates heat. You can change it in Settings > Privacy & Security > Location Services.
  7. Even because of GPS, if you find your way with the Maps app, it affects your smartphone.
  8. Turning on Airplane Mode turns off GPS, Bluetooth, Wi-Fi and cellular data all at once. Just tap the airplane icon in Control Center.
  9. There is a way to completely turn off your iPhone when not in use, if you don’t mind being alerted. Long press the sleep button and follow the on-screen instructions to turn the power off. 
  10. To cool your iPhone in the car, stick it in front of the air conditioner vent with Miracase or Bigseed’s magnetic iPhone holder.

If you can keep your iPhone at an acceptable temperature in the above way, you’re lucky, but if you don’t, you’ll have to schedule an appointment with an expert at Apple’s Genius Bar.

While it is unlikely that the weather will exceed this range throughout the year, unprecedented heatwaves and fires are currently being reported in the Northern Hemisphere as a result of the climate crisis. Temperatures outside the range a few times are fine, but caution is advised in areas with extreme temperatures.

This temperature refers to the range in which you should be careful when using the iPhone. Apple advises that it is safe to store iPhones between -20 and 40ºC.

Be especially careful about leaving your iPhone in the car in the middle of winter or summer. Significant deviations from normal operating temperatures, whether winter or summer.

What Happens When Your iPhone Overheats?

If it overheats rapidly, a message appears saying, “Your iPhone needs to be cooled down before using it.” Usually, it appears in white text on a black background, and an overlay notification appears when using the navigation function.

End use and turn off your iPhone as soon as possible. Reduce the temperature after moving to a cooler environment. After the notification to lower the temperature appears, the following changes occur:

  • iPhone stops charging
  • The display brightness is dimmed or turned off.
  • Cellular communication enters a low power state. The signal may be weakened. 
  • The camera flash is temporarily disabled.

It may be embarrassing when you first see the notification screen, but it is not a big problem except for the inconvenience of being temporarily unable to use the iPhone.

Should I worry about iPhone temperature?

Generally not. Apple notes that it’s normal for your iPhone to get hot temporarily when performing complex tasks like updating, restoring backup data, analyzing data like photo face tagging, or launching AR apps. When the operation is complete, the device temperature returns to normal.

How likely is the iPhone to explode?

The probability of an explosion is very low.

There have been reports of iPhones overheating to extreme levels. It is reported that a driver in Florida, USA, saw smoke rising from an iPhone while driving, picked it up, but dropped it because it was too hot, and melted the car mat. However, no similar incidents have been reported since.

In March 2017, CCTV footage was released of an iPhone 6 Plus smoking at a repair shop and a repairman dropping an iPhone in surprise. Shop owner Simon Owen interviewed that the service counter had melted and left a large hole.

In this case, it can be assumed that some kind of explosion occurred when the broken screen was pressed while the iPhone was already damaged. At the time, a Twitter user shared an experience with the iPhone 7 Plus exploding. In this case, the case was assumed to be the problem.

Fires and explosions caused by overheating often happen not only on iPhones but also on Note 7. It is necessary to store the smartphone in a safe environment and be careful not to rapidly increase the temperature.
