In winter, the temperature is below zero, and the ipad air2 can't be charged (it was charged for half an hour, but it didn't charge at all). Is it a machine problem or the weather is too cold?

The technical staff of the Apple brand said that the Apple device has a temperature protection setting, and the normal use range is generally ~35℃. If it is too low or too high, it will give a warning or even automatically turn off the power. It is recommended not to charge when the ambient temperature is too low or the mobile phone is hot, otherwise it will affect the battery life. The temperature is low, and the Apple brand heating wire can't work. Apple electric heating wire will only work at 25.1 1℃, otherwise it will not be heated.
