Apps and games of smartphones have become complex and taxing on the processor of the phone. A 15-minute PUBG session can cause the phone to heat up significantly — you can easily see temperatures up to 50°C —  which is a sign that you should probably take a break and cool it off a bit.

Background Processes

Applications such as Facebook and Twitter constantly run in the background to refresh and update their content so that you will have the latest post ready whenever they’re opened. While this might be useful for some, it’s an annoyance to many because this can cause a device to heats up and also affect its battery life.

You can force close these apps in the process manager or use hibernation apps such as Greenify, Hibernation Manager to force close and block these apps from running in the background.

Constrictive protection

In the interest of protection, users often use constrictive cases and screen protectors to safeguard their phone but little do they realise that the very thing that’s protecting their phone is also cooking it.

Phone is a handheld machine, and like any other machine it uses energy, which dissipates heat. If you put an extra layer — protective cases here — it becomes harder for the heat to escape, hence causing the device to heat up more.

Underclocking and malware

Do you also experience a slowdown with your overheating phone? It might be because the processor is underclocking to cool your phone as a safety precaution. It can also be a pesky malware running in the background. So, it is also best to check your phone for malware just to be on the safer side.

Dirt buildup

According to a report published by Time, your phone is 10 times dirtier than your toilet seat. Screen protectors can also contribute to the dirt and muck buildup on your smartphone because they’re constantly being used. This in turn also traps heat and suffocates your phone.

It is a good idea to get that Kleenex box and wipe your phone down every once in a while.

Heating up during charging

The process of charging normally heats up the phone as a high voltage current is passed. Modern smartphones come with some or the other form of quick charging feature that passes higher voltages and worsens the condition. Most phone manufacturers recommend to avoid using a smartphoen while charging.

You should also avoid charging till 100 percent all the time as it would deteriorate the battery faster. 85-90 percent is recommended for a healthy battery.

Also, inspect your charging cable, brick frequently for any damage and only replace with a manufacturer approved original spare if required.
