Ipadpro cannot be charged in cold weather.

Any electronic products that need batteries should not encounter too low temperature. Try to put your mobile phone in your pocket or bag when it is outdoors in low temperature. Apple's customer service staff suggested that it is best to charge the iPad in a place with heating or air conditioning in winter. "If there is no heating, cover it with a quilt or something and charge it." "Generally, lithium-ion batteries will be equipped with low-temperature protection, because low-temperature charging will lead to the deposition of lithium metal in the battery, which will lead to short circuit inside the battery." The low-temperature protection of the lithium-ion battery of mobile phone is set at about 0℃, and the lithium-ion battery of notebook computer is set at about 5℃. "This is for the sake of safety. The larger the battery capacity, the more dangerous it is. The iPad is closer to the computer and may have a higher level of protection. "

We opened the Chinese manual of the iPad and found that there was only one line: "Please use the iPad where the temperature is always between 0℃ and 35℃". No wonder users can't charge when the room temperature is between 0℃ and 8℃ in winter.
