The reason why mobile phones can't be charged in winter

In winter, the mobile phone can't be charged because its battery is protected at low temperature. The so-called low-temperature protection means that when the temperature is too low, the lithium metal in the battery will be deposited and will no longer react with the substance, thus causing a short circuit inside the battery.

Charging temperature

The optimum temperature for the chemical reaction of lithium battery during charging is above 10℃, so it is best to charge in a warm room, otherwise it will easily damage the battery.

Low temperature protection

In winter, the mobile phone can't be charged frequently, and the low temperature protection of the lithium-ion battery of the mobile phone is about 0℃. It can't be recharged temporarily, and it won't affect the quality of the mobile phone. If you encounter such a problem, you can basically boil it down to temperature if you can't find other reasons. Users can choose to turn on the air conditioner or heat the mobile phone with a quilt, so that they can charge normally.
