Action Taken:
1. Settings
2. Wireless and Network
3. Wifi Settings
4. Click Menu Button (next to Home Button) and Select Advanced
5. Select Wi-Fi sleep policy
6. Change it from "Never" to either "Never when plugged in" or "When Screen turns off".

Update - I went to bed last night before midnight with this setting with battery at 70% and this morning at 8am the battery was at 64%. Since it only used 6% over 8 hours, this worked for me. I have a GS2.

I agree with the people stating that it will use up more of your data package with your carrier. I'm going to review my data usage for the last 2 months to see how much hspa+ data it was using during the night before update to 2.3.6, after update to 2.3.6, and last night.
