How many degrees does Apple's mobile phone freeze?
Extended data:
Lithium batteries will reduce their capacity at low temperatures to protect themselves. Therefore, in a cold environment, the battery life may be shortened, for example, electric vehicles will ride for a shorter time in winter. But this situation is only temporary. When the battery temperature returns to normal, the battery life will also return to normal.
When the ambient temperature is high, the mobile phone battery can adapt to MINUS 20 degrees Celsius to 60 degrees Celsius. When the surrounding environment is below zero, it will be difficult for it to adapt to this situation, its performance will also decline, and its power protection will gradually weaken, which will affect the normal work of the mobile phone and eventually lead to its shutdown.
Mobile phone battery consists of three parts: battery core, protection circuit and shell. At present, all mobile phone batteries are lithium-ion batteries (often referred to as lithium batteries in irregular situations), and the cathode material is lithium cobalt oxide. The standard discharge voltage is 3.7V, the charging cut-off voltage is 4.2V, the discharge cut-off voltage is 2.75V, and the unit of electricity is Wh.
