You might not realize it's there if you have other Google Play Services being used. Overall it drained about 3%-5% of my battery with 30-40mins of awake time.
The service was called ApiService under one of the Google Play Services found in Settings > Apps > Running. Since doing this it hasn't come back. Also clearing this data cache doesn't cause you to lose any settings.
Updating the original post with a screen shot.
