Lithium-ion batteries work on the principle that the internal electrolyte changes through a chemical reaction, resulting in a potential difference between the positive and negative electrodes to generate an electric current. At low temperature, the electrolyte moves very slowly, which affects the transfer activity of lithium ions between the positive and negative electrodes, resulting in the deterioration of battery charging and discharging performance.
Depends on the temperature. As long as it's not 15 below. Charging above zero is 100% unaffected.

Charging speed will slow down in sub-zero environment for a long time. In a low-temperature environment, the low-temperature protection mechanism of the lithium battery will start, resulting in a slow charging speed, and it is good to put the earphone on the warm bag.
