What is the reason why Xiaomi 10s is cold and power-off is fast?

Because Xiaomi 10s uses lithium batteries.

The negative electrode of lithium battery removes lithium ions through chemical reaction, and the lithium ions are embedded in the positive electrode through electrolyte solution transmission, thus generating current to power the mobile phone. At low temperature, the viscosity of electrolyte solution increases, which leads to the deterioration of lithium ion permeability, decrease of activity and increase of resistance. The discharge voltage of the battery decreases, which reduces the available capacity of the battery and makes the power consumption of the mobile phone faster.

Xiaomi is an Internet company and an innovative technology enterprise, which was founded by Lei Jun and Wang Chuan on April 20 10.
