While there could be various reasons for overheating, here are the most common reasons why you are facing this issue:
 
  1. Your video quality settings are not suitable for your device. CS gives you automatically adjusted video quality settings for the best optimization but if you have changed them into higher standards that are burdening your GPU (Graphics Processing Unit) or your device is not supporting, it is likely that you will face with overheating issue.

    **If you don't know how to check your video quality settings and FPS issues, check this article.
     
  2. You might be facing overheating because your device's RAM capacity is running out of space. Try closing background applications.

  3. When you overburdened your device with multiple tasks and application running simultaneously for a long time.
When you face this overheating issue, please try the following steps:
 

Clean the cache of apps on a regular basis

In such case, we recommend cleaning the cache of the applications found in your device or uninstall/ force stop the ones you haven't used for a long time. This will create space both for your RAM and storage and allows your device to process the current applications faster and easier.
 

Lowering graphic settings

As we have mentioned above, higher standards causes a heavy burden on your GPU and this will make your device hotter than usual.
 

Avoid using multiple apps simultaneously

Do not run multiple applications at a time. This could drain your battery faster and uses all the space for your RAM. Insufficiency of RAM causes your game to crash/ freeze and device to overheat eventually.
 

Try not to play while your charger is plugged-in

This will affect your battery life extremely negatively and causes your device to overheat more than usual. For a better performance and a battery life, do not play or use your device while your charger is plugged-in.
 

Do not use your device under direct sunlight

Using your device under direct sunlight causes your device to overheat as well.
