Why do many mobile phone batteries run dry when they are cold?

Was recently in the ski and 30% battery my mobile goes out (huawei). The same with my mother (apple)

When my phone was against warm we went against normal

Batteries (especially LiIon and LiPo) lose their capacity due to the cold. This will empty them faster. The notes the electronics in the device (whether cell phone or something else) and turns it off when undervoltage. So that's not the cell phone, but the battery technology.

This is especially stupid in the modeling sector. Since you take extra Heizkoffer to warm the batteries before use, so that is not all the time after all.

Batteries are based on using chemically bound energy. When it gets cold, these chemical processes can no longer run properly.

In addition, protection circuits are installed to use the battery from destruction.

But almost everyone knows it, if you have problems with the car battery, then in winter. Simply because the cold disturbs the processes and thus the performance drops sharply.

Suspect that the battery degenerates when it is cold. So chemical processes irreparably damage the battery. That's why the phone turns off.
