Apple Health: The Best Check iPhone Temperature App

The iPhone has its own app called “Apple Health,” which you can use to measure the temperature of your iPhone. It works by connecting to the external smart thermometer, and this thermometer provides the exact temperature value.

But that’s not it.

According to Apple, the Apple Health app can help you access your medical information easily. They will be your finger taps away if you download this app.


The second app you can use to check iPhone temperature is Kinsa. Although it is a medical app, it can also be used as a “Check iPhone temperature app.”

That’s all about how to check the iPhone’s temperature. Now, it’s time to know why the iPhone’s temperature rises significantly.

Why iPhone Temperature Rises (Overheats)?

There are many reasons which can increase the iPhone’s temperature. These are:

  • Any updating process (as it consumes a lot of battery)
  • Structure limitations (iPhones do not have any fan to cool the heat)
  • Running processor-intensive functions such as games, using GPS navigation, streaming HD videos, etc. 
  • Bugs in outdated apps that increase the workload of the processor 
  • Faulty or old battery
  • Exposing your iPhone to Sunlight. 
  • Running too many apps simultaneously can put much pressure on the processor.

Because of the things described above, your iPhone works harder to manage all of the functions, which can generate more heat.

What To Do If iPhone Temperature Rises?

If the temperature of an iPhone rises, you should immediately do these things to keep it under control:

Close All Background Apps

To cool the raised temperature of an iPhone, close all of the opened apps on an iPhone. If you do this, the workload of the processor is decreased, and eventually, it cools down.

Restart your iPhone

If you do not know or have time to turn off all the apps, you must restart your iPhone. Doing this will close all the opened apps.

To restart the iPhone: 

  • First, press the power button and any volume button at the same time. 
  • After a few seconds, a slider will appear. Drag it to the right, and the mobile will power off. 
  • Then, wait for a few minutes so that the iPhone cools down. 
  • Next, turn on the mobile by pressing the power button for a few seconds. Release the button when you see the apple logo on the screen.

Remove the Case

When your iPhone gets heated, remove its case as it traps heat and prevents it from discharging. By removing the case, the airflow will also increase. You should also keep your iPhone in a cool place or under a fan to further cool it down.

In addition to this, you can also do some more things to reduce the iPhone’s temperature:

  • Keep your iPhone up-to-date, as many performance improvements come with upgrades. 
  • If your phone gets heated during charging, then remove it from charging. 
  • If it is exposed to direct sunlight, then remove it from sunlight. 
  • You should also turn on Power saving mode and also turn on the “Auto Brightness” setting.
  • Delete the extra widgets.
  • You can also reset the Settings.
  • While playing games, if it gets heated, then stop playing games to cool it down as it draws pressure on the processor.


What Is the Normal Temperature of an iPhone?

The normal temperature of an iPhone is 32º – 95º Fahrenheit (0º – 35º C) at 5 – 95% relative humidity. iPhones do not work smoothly if the temperature goes below 0º C, and it specifically does not operate at -4º – 113º F (-20º – 45º C). Similarly, if the temperature increases from 100℉, iPhones can get permanently damaged. 

Does the iPhone have an in-Built Temperature Sensing System?

Yes, the iPhone has in-built temperature sensors. These sensors are added to monitor the battery and processor’s temperature. 

In case of extreme temperatures (hot or cold), these sensors shut down. They do this to prevent damage so that you can keep using the iPhone.

Final Remarks

So, how to check iPhone’s temperature?

You can check the iPhone’s temperature by going into Settings, opening the General option, and then visiting “About.” You can also know how hot the iPhone is with the help of an infrared thermometer and thermal camera. In addition, third-party apps like Apple Health, Kinsa, etc., are also effective in measuring the mobile’s temperature.

With these easy methods, you can get accurate readings/measurements of the iPhone’s temperature in no time.
