When your phone is not in a suitable network area, then it always searching for a better connection. During this process, your phone’s processor got heated up and you feel lag.

You can try out every SIM card provider and then choose the better suitable battery connection SIM card company for your phone.

6. Don’t expose the phone to Sunlight:

If you are exposing your phone to heavy sunlight, then it not only overheats your phone, but the consequences are very worst. Like you can see battery draining or damaging issues, display issues, etc.

So, try to keep your phone inside your pocket, and use it when it’s needed.

7. Hot Environment:

If you are living in a place where the temperature is very high or you working somewhere in a hot environment then you can easily use it with the heating issue.

If this is the reason, then keep your phone aside in some cold or balanced temperature place. And save your phone from being overheated.

8. Remove unusual Apps:

Sometimes, we download apps for one-time use, and then we forget to delete those apps from our phones. And those apps create so many issues and problems in our phones like battery using, lagging, lack of storage, etc.

Those apps are running in the background and taking more data from our phones. So, find which apps are not in use and delete those apps from your phone.

9. Turn Off Useless Notification:

When you turn on your phone’s mobile data or WIFI, you receive many notifications and also feel a lag in your phone. We receive many notifications on our phones in a day, some are useful and some are useless. We receive notifications like matrimonials, app updates, deals, and more.

Those notifications are so annoying and power-consuming. So, Stop notification of those apps, because those also lead to heating issues in the phone.

Brightness is also a factor in the heating issues in your phone. If you always keep your phone in heavy brightness, then it also leads to a heating issue.

11. Stop Background Apps:

We use many apps in a day and forget to turn off those apps. And those apps keep running in the background and consuming data, power, and storage. And background running apps are also leading to heating issues in your phone.

So, when you finish using that particular app then please close that app from your phone. And also from the background running. This will also help you to fix this issue.

Non-supporting apps can also lead to heating issues in our smartphones. And some non-authorized apps also.

Sometimes, we want to download some app, but that particular app doesn’t available in Play Store. You could not find that app in Play Store, but you wanted to download that app. So, we download that app from other non-secure websites or some other app stores.

And then, those apps start creating many types of issues in our phones, like some non-relevant permissions, data consumption, and all. So, you should not download those apps from another side.

Because, if any app is not available in the play store that means that particular app is not safe for our phone. And that app is not approved by Google. Google never promote apps, which has privacy and security issue. If you could not find that particular app in Google, then there are many alternative apps available in Play Store. You can use them.

In Play Store all apps are totally secure and safe, if google finds any app making any type of data leaking or if they caught any apps breaking the rules, then that app will immediately get banned or removed from the play store.

14. Disable Location / GPS:

We download many apps on our phones. Some app needs our phone location initially and some need it when we use that app, to give us a better result. After giving the location permission we forget to turn off the location on our phone. And that leads to heating issues in our smartphones.

Next time always keeps in your mind that you have to turn off the location. Only enable when needed.

15. Avoid Using the Camera for a long time:

Capturing photos or recording videos for a long time can also lead to overheating issues in your phone. Most importantly when you record videos in 4K resolutions.

Just stop doing this, your phone is just a phone, not a professional camera.

  • Stop recording in 4K resolution always.
  • Don’t use the camera for a long time.
  • Try to make a video on 1080p or 720p resolution.
