Why Apple's mobile phone battery is not durable in winter?

Using an iOS device in a cold environment will temporarily shorten the battery life.

If the user turns off the phone automatically in cold weather, he can call Apple Customer Service, quote the IMEI serial number of the mobile phone and check the battery hardware status. If the battery is ok, it is recommended to upgrade the system. If upgrading the system still cannot be solved, users may have incomplete installation of software packages when upgrading the system. "You can't really determine the specific problem before testing the motherboard at the maintenance point."

Technicians said that using an iOS device in a cold environment below the working temperature range may temporarily shorten the battery life and cause the device to turn off. It is recommended to use iOS devices in an environment with a temperature between 0℃ and 35℃.

Professor Li from the Department of Communication Engineering of Beijing University of Technology said that the capacity of mobile phone lithium batteries will indeed decline when the temperature is too low, but it should not be affected above 0℃.

He said that the automatic shutdown of the mobile phone may be due to the aging of the battery performance curve, which leads to the inaccurate percentage of battery power displayed, or it may be due to the aging of the battery. In some applications that need to consume large current, if the internal resistance output is not enough, it will turn off. "If you shut down frequently, you need to go back to the factory for inspection and maintenance."
