Apple's mobile phone turns off automatically when it gets cold.
Low temperature will cause the internal resistance of lithium battery to increase and the current to decrease, resulting in fast power consumption of mobile phone. Lithium batteries need very high temperatures. If the temperature is too low, the activity of lithium ion will decrease, resulting in insufficient voltage of Apple mobile phone. What's more, the CPU of Apple's mobile phone will restart when the voltage is insufficient, which will do great harm to the mobile phone. It is better to turn it off directly.
The reason why Apple's mobile phone sets a temperature protection mechanism for the battery is mainly to prolong the life of the mobile phone battery, which is partly due to the consideration of consumers. The low-temperature protection function of the battery is turned on, and it is recommended to be practical in the environment above 10 degrees, especially in the north. Try to avoid using mobile phones outdoors in cold weather, otherwise it will easily lead to the phone being turned off.
Automatic shutdown processing method:
Putting a furry mobile phone case on the mobile phone can alleviate the influence of cold weather to some extent. Carry a charging treasure with you, the mobile phone will heat up when charging, which can form a good resistance to the surrounding low temperature. But these methods can only play a certain role, and there is no particularly good way. Some people will stick a warm baby on the outside of the phone case. Although effective, this method is extremely dangerous and is not recommended.
If you want to return to normal as soon as possible, you can use a hair dryer to blow the back cover of the iphone or iPad to a slightly hot temperature of about 40 to 50 degrees. In fact, the discharge process of lithium-ion batteries is also affected by low temperature. For example, there are many cases where the iPad cannot be charged at low temperature.
