Why does the mobile phone consume power fast in cold weather?

In cold weather, when the ambient temperature is too low, the battery capacity of the mobile phone will plummet with the decrease of the temperature, which will eventually lead to the shutdown of the mobile phone. The specific reasons are that the cold environment can't release the battery, the electrolyte will thicken, the activity of the lithium battery of the mobile phone will decrease, the chemical reaction speed inside the battery will slow down, and the power consumption of the mobile phone will increase.

Extended data:

Low or high temperature environment may cause the equipment to change its behavior to adjust the temperature. Using an iOS device in a cold environment below the operating temperature range may temporarily shorten the battery life and cause the device to shut down. When the equipment returns to a higher temperature environment, the battery life will return to normal.

To protect the battery, it is necessary to turn off the power consumption services of mobile phones in time, such as mobile phone positioning, Bluetooth, hotspot WiFi, etc. It can also reduce the resolution of the mobile phone and the brightness of the screen. Turn off the background running software of the mobile phone, and the background application on the mobile phone will be cleared in time. In the battery management option of the mobile phone, the background application of the mobile phone will be restricted, and the background application will be automatically cleared after 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 charge cutoff voltage is 4.2V, and the discharge cutoff voltage is 2.75V.
