I had the same problem on my Samsung Galaxy S2 just starting this month (July 2016). I tried disabling all the GPS and syncing, and I rebooted, and I reset several times, to no avail. I even downloaded some app that was supposed to help. Nothing worked. When I looked at the battery usage, "Google Services" accounted for over 95% of the drain. My fully charged phone would be hot and totally drain in 90 minutes, even on standby. What worked for me was to disable the Google Play Store. I went into applications (the all tab) and clicked on the store and disabled it, and now my phone is totally back to normal. I verified this when last night I wanted to download an app, and needed to re-enable the store. I did not disable it, and my phone was hot and the battery draining again. I just disabled it again, and the phone is normal-temperature again. Hope this helps someone!
