Plug [Q] Problem with google play services process

HI, i have a big problem with my Xperia device, or at least, i think so. At the end of the day, with a non-heavy usage, the screen spend a 30% between 3 or four hours, that is good, but google play services spend the 40%, this is too much i think, and i have auto-sync off, and all this stuff, so i donít know why it waste such a lot of battery.
