When using an Apple mobile phone in winter or in a cold environment, the Apple battery will not be durable and the battery life will be shortened. Is it possible that the Apple battery will hibernate in winter? In fact, the performance of the battery is reduced in a low temperature environment, and the capacity is reduced.

　　Through the test of Apple battery, the battery capacity is significantly reduced in a low temperature environment, which shows that the battery capacity is greatly affected by the ambient temperature. Apple batteries are lithium batteries, which are mainly composed of a positive electrode, a negative electrode, and electrolyte. When the battery is discharged, the negative electrode undergoes a chemical reaction to decompose lithium ions, which are transported to the positive electrode through the electrolyte, that is, the positive electrode is in the lithium-rich state and the negative electrode is in the lithium-poor state. During the lithium ion transmission process, electrons move to generate current. When the ambient temperature is too low, the chemical reaction of the battery will be slow, and the discharge current will decrease, resulting in a decrease in battery capacity.

　　The charging and discharging performance of Apple batteries will also be affected by the ambient temperature. In a low-temperature environment, the constant current charging of the battery will shorten the full charge time, while the constant voltage charging time will be prolonged; the discharge performance will be significantly reduced and the discharge capacity will be reduced. At this time, when the Apple battery temperature reaches normal temperature, the battery capacity will return to a normal level.
