Why is "Samsung Push Service" using so much of my battery?
I couldn't stop it (or do anything at all) from Settings -> Applications -> Manage Applications -> All -> Samsung Push Service.

I opened "Samsung Apps" and it prompted me to upgrade. After that had completed, I went to Settings -> About Phone -> Battery Usage -> Samsung Push Service and chose Force Stop, as it still seemed to be running heavily.

Upon powering the phone off and on, the App started up again, but no longer keeps the phone awake. I see it's now running version 1.1.4, which may have fixed the problem?
