When using your iPhone, have you ever noticed that the charging speed of your iPhone slows down in winter, or even fails to charge?

#Why does iPhone charging slow down when the weather is cold?

Lithium batteries are afraid of cold and heat. In low temperature environments, the internal chemical reaction speed of iPhone batteries decreases and the discharge current becomes smaller, resulting in slower charging speed. In order to protect the battery, Apple's system has set up low-temperature protection. Under low-temperature conditions, it will automatically reduce the charging speed and maximum charging capacity. When the temperature is lower, it will even stop charging and shut down to avoid damage or shorten battery life. If you want to increase the charging speed of your iPhone in winter, you can move the phone to a warm place indoors to charge, or wait for the phone to heat up before charging.
