6 ways to cool down when your smartphone is too hot

Below is a list of common reasons and solutions to limit the situation of smartphones overheating abnormally.

1. Use genuine charger

Most of the "fake" chargers sold at cheap prices are often of poor quality, with unstable currents, leading to abnormal heating of the smartphone, battery failure, and even explosion, causing serious effects on you and your family members. That is why you should only use the genuine charger that comes with the product or devices that are capable of automatically adjusting the current and have been certified.

2. Charge your phone properly

If the temperature during the day is too hot, you should only charge the device to 70-80% and charge it fully at night. Most smartphones today use Li-ion or Li-po batteries, so they will not have a “memory effect”, which means you can charge your smartphone at any time without having to wait until the battery runs out.

3. Limit opening multiple tasks at the same time

If your smartphone often heats up abnormally, it is likely that it is overloaded. To fix this problem, you should temporarily turn off unnecessary applications, use the Lite versions of Facebook, Messenger... instead of using the "official" version.

4. Battery failure

First, open the back cover of the phone and check if the battery is swollen or not. If so, users just need to bring it to a reputable repair shop for replacement.

5. Remove the case

In addition to beautifying and protecting the phone, sometimes the phone case is also the reason why the smartphone heats up. Therefore, if you are using a case, you should temporarily remove it and check the temperature of the phone.

6. Outdated software

Outdated software is not the main factor that causes smartphones to heat up, but it does make the phone run less smoothly. Besides, users should also clear junk files, caches, etc. on smartphones to speed up the device.
