14 Ways To Prevent Your iPhone From Overheating While On Facetime

When you are on facetime, your iPhone runs multiple processes at the same time. Although there can be many reasons for your iPhone to get hot, you can prevent this by following the tricks mentioned below!  

1. Switch to the WiFi if you were on Mobile data

If you have noticed your iPhone is getting hot while you are on facetime, check whether you are using mobile data. If yes, then you need to switch on to a reliable Wi-Fi connection. Fast Wi-Fi connection helps your video chatting go smoothly. It is also possible that your phone will stop getting hot after that. So, try it and pay attention if there is a difference.

2. Enable Low Power Mode

Turn on the Low Power Mode feature of your iPhone, if it is getting hot while on facetime. This is a cool feature that turns off all the background apps running, cancels auto-downloads, cancels fetching notifications or emails automatically; and helps your device to run effectively with the lowest consumable power.

To enable iPhone’s Low Power Mode:

  • Go to the Setting app. 
  • Scroll down to open Battery.
  • Toggle on the Low Power Mode feature.

3. Check your iPhone’s Case

Sometimes your iPhone’s battery fails to dissipate heat to the air because of the phone case. Therefore the case can be a reason for your iPhone to get hot. Remove the case and see if there is a temperature difference while video chatting.

4. Turn Off Location Services

If you are on facetime and moving to places (traveling) while the GPS is turned on, your phone may overheat due to that. So turn off your iPhone’s location services if possible and enjoy facetiming.

To turn OFF the iPhone’s Location Services:

5. Turn ON Auto Screen Brightness

A constant high brightness consumes a lot of battery and CPU power of your iPhone. And while being on facetime, it can be a common cause for your phone to overheat. Thus you should enable the auto-brightness feature of your iPhone.

To turn ON auto-brightness:

  • Go to the Settings app.
  • Scroll down to open Accessibility.

You can set the screen brightness to its minimum, but while being on facetime most users do not prefer that.

6. Stop Charging your iPhone while on Facetime

Many users seem to talk on facetime or use their phones while charging it all at once. This leads the phone’s battery to overheat which overheats the device. If you are doing the same, you should avoid charging and using your iPhone at the same time.

7. Close Background App Refresh

8. Stop playing Games at the same time

This measure belongs to those who are a fan of heavy streaming and playing high-quality HD games on their iPhone. In fact, they even do it when facetiming at the same time. For any device, multiple heavy processes running at the same time are very overloading to bear. Thus it should be avoided to prevent your phone from overheating and getting damaged.

9. Close Unused Apps

Apps running in the background can lead your iPhone to overheat while you are on Facetime. Being on video calls, you should avoid using other apps and also close apps that are running in the background.

iOS devices are designed to work well in an environment where the temperature is normal. The temperature should be around 16-22°c – according to Apple. So if you are facetiming while being at a place against the iPhone’s bearable temperature, then you should try to switch that place immediately. Check if that helps.
