Battery level decreased fast during cold conditions

[Ramarathon]

My Adidas Ionic has a battery life up to 5 days without running exercise.

since a few weeks, when I start to run my watch shut down after approx. 15 minutes.

Yesterday I start to run with a battery level of 53%, after 20 minutes the watch shut down, after re-connection with the charge cable it started up and shows a battery level of 33%  

This problem started after it was getting cold weather around 3 degrees.

Someone knows a solution?
