What are the Operating Temperatures of the iPhone?
The ideal operating temperature for iPhone is between 30° to 95° F. The iPhone’s performance is excellent and seamless in this range.
However, leaving your iPhone in a hot environment, such as on the surface of a hot car, exposed to extreme cold, or in direct sunlight, can bring the temperature warning screen. A temperature warning is a built-in sensor in iPhone that immediately shuts down the device if it gets too hot.
So your iPhone gets temporarily disabled and gradually cools down. Then, it goes into a cool-down mode where you can only make emergency calls.
Reasons for iPhone Overheating
There are several reasons for iPhone heating. Some processor-intensive activities lead to iPhone heating. However, once these processes are complete, your iPhone returns to its average temperature. Keep in mind that these activities do not display the temperature warning; they include;
- Streaming HD videos

- Heavy downloading
- Playing games
- The camera flash turned on for too long
Some technical and hardware issues lead to a hot iPhone. Some other reasons for an overheating device are;
- Battery Failure
If you have an old Apple device, it is most likely to have a battery malfunction. Faulty and old batteries deliver inconsistent energy output. As a result, it leads to poor battery life and quick drain that can easily make your phone hot.
- Too Many Apps Running in Background
Running more than two apps can negatively impact your phone’s performance. It puts a considerable strain on your device’s processor, making it perform harder, which can make your iPhone hot.
- Expose to Hot Environment
Keeping your phone near or in a hot environment can also lead to overheating. Apple devices have sleek infrastructure that makes them easy to overheat. Please avoid direct sunlight contact.

Most times, it is primarily the outdated or buggy apps that increase your device workload. As a result, your device gets too hot.
What Happens To A Hot iPhone?
An overheating iPhone will warn that your iPhone “needs to cool down before you can use it.” This is also called a cool-down mode, where a hot iPhone restricts the user from using it. A hot iPhone will show the following things during the cool-down mode;
- Hot iPhones stop charging

Step 1. Connect your iPhone to a desktop device through a cable and open iTunes on the desktop. Make sure your iOs device is shut down but connected to iTunes.
Step 2. Press and hold the button present on the side for approximately 4 seconds. While holding this side button, press the Volume-down Button and hold it simultaneously for 10 seconds.
Step 3. Release the side button first after 4 seconds but hold the volume-down button for over 6 seconds.
Step 4. After 10 seconds of holding the volume-down button, the iPhone’s screen goes black but brightens slightly. This is because it indicates your iPhone has entered DFU mode.
Turn on your device through the power button once it is cooled down.
iPhone overheating is always something to worry about. Apart from the abovementioned tips, you can try toggling location services and wi-fi to let the phone gradually cool down. This will save you the extra cost of getting the device repaired.
