Charging, Power Supply

Why does the charge LED turn green before a 100% charge is reached? Why won't the watch charge up to 100%?
Charging in a location where it is extremely cold or hot creates the risk of deterioration of the built-in battery, which will automatically limit charging to protect it.
Under such conditions, you may not be able to achieve a 100% charge.
Charging within the following temperature range is recommended: 10℃ to 35℃.
