Thanks for your reply.
Yeah there's definitely something strange happening with googles services. I assume the real fix will come in the next update,which should be the big KitKat update. I've seen that they have updated the OS in this area (how much apps are using battery and data) meaning that you will have more control over issues like this.
As mentioned before, even after making sure everything is syncing properly. You will still see Google Services appear in the battery list, but it should not use anywhere near the amount of battery it was before.
I have noticed the Google services appear in the list early in the morning, but over the course of the day, the amount of battery it has used is minimal.
Also services such as Google Play, which continuously checks your location and learns about you and your phone will obviously be trying to bounce info across to Google.
Also I noticed in another thread, there is an app called "SnapDragon Battery Guru", made for devices like the Galaxy S4.
I'm new to the app, but it promises good things.
Apparently it will learn from your daily routine (like how often you use your phone, when you normally charge it, and when you connect to wifi), after a few days it'll pop up and suggest ways to maximise your battery life.
Things like: making apps only sync around the times you normally use them, turning wifi off at times where you usually do not have a connection (and back on again) and an especially cool one... since it knows when your usual charge points are, it'll let you know when you may not have enough battery life until you reach your next charge point, and prompt you to give the battery a boost.
Well worth a look if you are concerned about battery life.
hope this all helps
