I noticed my Google Services being at 80% for most of the weekend, absolutely draining my battery. After doing some research on another forum (not sure if I can mention name on here?) I realized my google play store was only on version 3.x. I downloaded the .apk for version 4.1.10 and seemed to improve. From there, I went into my Location services and unchecked wi-fi & mobile network location. This sends your location data to Google as they wish. Also make sure that the google maps location setting is unchecked or else Google apps can use your phone's location whenever the device is on.
Did all that and now my battery is so much better. Give it a try and see how much it helps.
