On summer days, when you forget your phone for a long time, you will feel the heat and temperature much higher than usual. You may even see a warning that your phone has to stop working because it is too hot.
So, how to "cool down" the phone? According to Cnet, you need to do the following things immediately: turn off the phone, avoid direct sunlight (put in the bag or under the shade), remove the protective case if you are using it, disconnect the charger if you are charging. If there is a fan or something like that, turn on the fan for it to speed up the cooling process.
The phone may also heat up while in use. For example, if you play a "heavy" game, it will get hot. In this case, it is not so hot that the warning is displayed but if you feel uncomfortable, you should immediately turn off the game or the running application, giving the phone time to cool down. Disconnect the charger if it is charging. Reduce screen brightness. Remove the protective cover.
If the phone heats up abnormally, perhaps the problem is inside. You should contact the service center for inspection. In addition, you should also follow the following tips to avoid overheating smartphones: do not leave your phone in the car on a hot day, do not use your phone directly in the sun, take breaks during a game or watch video, avoid charging while playing games or watching movies.
