What's wrong with the cold weather and the fast power consumption of mobile phones?

The activity of lithium ion decreases at low temperature, which leads to shorter standby time of mobile phone and faster battery failure. The negative electrode of lithium ion battery removes lithium ion through chemical reaction, and the lithium ion is embedded into 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 the ability of lithium ions to pass through the solution, the decrease of activity and the increase of resistance. This will reduce the discharge voltage of the battery and the available capacity of the battery, resulting in faster power consumption of the mobile phone. In the low temperature environment, the mobile phone itself may also have some heat dissipation problems. Due to the low ambient temperature, the heat generated by the mobile phone may be more easily dissipated, which makes the mobile phone need to consume more electricity in order to maintain the normal working temperature.
