Problem

The user finds that the watch's battery level drops rapidly or the battery life shortens significantly after a long period of use in low-temperature outdoor environments in winter.

Cause

Due to the chemical characteristics of lithium batteries, the battery capacity decreases significantly at low temperatures and the available power drops sharply. Therefore, you will find that the watch's battery level drops rapidly or the battery life shortens in low-temperature environments especially in winter.

Solution

After you return to a warm room with the watch, the temperature of the entire watch will increase and the watch's battery level will stop dropping rapidly and stabilize.

Low temperatures will not cause irreversible damage to the battery. It is recommended that you check the battery level before you set off if you are going to be doing outdoor activities for a long time in winter. Ensure that the battery level is high enough to avoid any unforeseen circumstances.
