iOS 6.0.2 Update not only drains battery but also broke notification center

Seems like the iOS 6.0.2 was one of the worst updates. Seems like it not only drains the battery but also came with a set of new problems:

1. Drains battery significantly when idle. I use to loose 1 or 2% through the night and now it is close to 10% and surprisingly when I pick the phone in the morning and get past the lock screen the battery drops 5 to 10% instantaneously.

2. Uses Cellular data even when WiFi is available specially once the phone is in sleep mode.

3. Notifications from CNN, and some of the apps no longer show up on the lock screen. How can I tell ? iPad mini doesn't have the issues and I am seeing the notifications on the mini but none on my iPhone.
