I was having this draining problem (happened out of nowhere, a full week after installing the 4.4.2 update).
Uninstalling Google Search and reinstalling it through the Play Store didn't worked (kept having Google Services draining more than 80%).
Setting Location mode to GPS-only didn't worked neither. Turning location off worked, but disabled my location-based apps, has expected.
What did worked for me was going to Setting -> Location-> Location Services (Google Location Report) and disabling both Location Report and Location History.
Now Google Services DOES NOT DRAIN more than 2% of my battery. CPU usage is always low (using CPU Spy Reborn, the 1512 MHz frequency step is pretty much around 2 - 3% of the time, as is the 1026 MHz frequency step - the remaining frequency steps are all at 0 - 1%, with 384 MHz (the lowest step) at 52% and Deep Sleep at 34% of the time).
All this with Location active on high-precision mode. Roughly 5h10min of usage (LTE always on), with PowerAmp playing for more than 4h straight, around 55min screen on and 15min or so of gaming (Zombie Gunship), and the battery is still at 72%.
With 4.3, with the same level of usage (moderate to heavy, I guess) the battery would absolutely be on the 60-65% range.
In other words, disabling both Location Report and Location History worked for me, with zero downsides with regards to location based apps (Google Maps, Waze and GPS Essentials all work perfectly).
Hope this helps. Best regards.
