The whole country is currently in "barbecue mode". High temperatures not only affect travel, but also have a huge impact on the use of mobile phones in outdoor environments. In response to the problem of mobile phones getting hot and performance degradation caused by high temperatures, many brands have responded.

Apple said that when the temperature is too high and the phone gets hot, the phone's energy consumption is reduced and the network speed will also slow down. Huawei said that the network speed is generally related to the signal and has little to do with temperature.

When using a mobile phone in hot weather, the ambient temperature will definitely increase, causing heating. It is normal for the mobile phone to limit its performance for temperature control. As long as the indoor environment returns to normal temperature, the performance will naturally recover.

In order to use the phone normally outdoors, some users will use some cooling accessories, such as ice stickers or wet wipes to cool it down, and some users will even use ice packs to cool it down directly. Some of these methods seem a bit too extreme, so they are not recommended by the official mobile phone company.

In hot and humid weather, if you use ice stickers or ice bags, the rapid temperature change may cause the water vapor inside the phone to condense into water droplets. In severe cases, it may cause an internal short circuit and damage the phone.

Apple technical support clearly stated that extreme low temperatures are also not good for the health of mobile phone batteries, because overcooling may hinder the chemical reactions inside the battery.

Obviously, in hot weather, you should try to reduce the use of your phone outdoors, lower the brightness as much as possible during use, and control the phone's temperature through software means.
