I still have drive.metadata.sync.syncadapter.StubContentProvider among the providers of Google Play Services and I have it disabled. Maybe it doesn't exist for some reason on your installation, in this case just ignore it.drive.metadata.sync.syncadapter.StubContentProvider, not founded (notifiation founded and disabled)? ok?
You are right that there aren't big differences between the two screenshots in terms of uptime and battery usage. Of course the screenshots can't show your user experience, but as you wrote, you are quite happy with bootup time, screen wakeup time, delay at incoming calls, phone responce etc.AND please if you have time take a look and compare closely the screenshots between the two posts, as IMHO there are not so big differencies.
May be i am wrong.
The discussion about disabling some Google Play services came up when users reported problems with system hangs and spontaneous reboots (bug #55).
It could well be that in the meantime Google has fixed some bugs, so that newer versions of the Google Play Services don't lead to bug #55 anymore.
If this is the case, disabling of services might not be so important anymore. If you are still willing to test, you could enable the disabled services, receivers and providers again and double-check if it has an influence on your user experience.
