Analysis of the causes of Apple mobile phone batteries

　　Apple mobile phone batteries are lithium batteries, which have the advantages of light weight and high energy, but the battery will explode when it is low.

　　The main cause of the iPhone battery is thermal runaway. Loss of control is a cycle of positive energy feedback. Simply put, the temperature rise makes the system heat up, and the system heats up the temperature to make the system hotter. The reasons for the thermal runaway of the battery are as follows. Many environments, such as temperature above 60°C, battery overcharge, physical damage to the battery, and thermal breakdown caused by the battery being waiting for the light-emitting film. When the chemical is heated to a certain level, it will self-heat and cause the battery to catch fire or explode.

　　The battery life of Apple mobile phones is about 2-3 years. During this period, avoid battery damage and cause the internal battery to become popular; the ambient temperature is too low or may cause permanent damage to the battery, so avoid using the battery in harsh environments; the phone is rained on the birthday Water, soaking, etc., to prevent the battery from short-circuiting.
