Battery drain since Yosemite

My battery has halved (5-6 hours) since I installed Yosemite. I tried to do an clear install, but don't it don't seem to be the solution. It's a macbook pro 2014, with least than 4 month. If i go back to mavericks the battery seems to work fine, so it looks like a Yosemite problem.
