Default Possible cause of push notifications not working?

So I've used several apps to fix the apparent kitkat heart beat signal (what keeps the ports from going inactive that most apps use in order for notification communications) that being said from what I know.

Anyhow, they only work for a little bit.. I have to keep applying the changes over and over.

Could it be that kitkat itself is putting it's push notifications services to sleep? I've factory reset over and over and clean flashed and everything.. No changes. The push notification fixers only keep it working for anywhere from 5 minutes to 2 hours. Then I cease to get notifications again.
