Battery drain on my Moto 360 (15%/h)

Dear users

I have extreme Problems with my Moto 360 battery. I bought it on 4 days ago and already charged it from 0-100% twice (and 2 times from about 20-100). The battery stats in the app are the following with 25% of Charge:
Android Wear 12%
Display 8%
Android-System 6%
my Watch Face 6%
Clock inactive 5%
wearfacematrix 5%
...
I already did a factory reset and tried to use an older Version of Android wear with no success. Ambient mode is off (even if I would love to use it), brightness on 1, turn on on tilt is on, WLAN on automatic.

In other Posts I saw People can use the wear for over 16h (I only use the watch to read the time once every 20 minutes and talk to Google about 5 times a day). Ah and I'm using 5.1.1 and 5.1.1 was installed from factory.

Please help me...
