I've been using the headphones for almost a year now and I'm having strange effects with the battery life. At first, the headphones lit up blue, but the battery was still only charged to 90% (according to the display in the settings on the mobile phone). Now, when charging for a longer period of time, it shows 100% again, but after a maximum of 6 hours it stops. This happened to me this weekend during 2 runs on Saturday and Sunday.
