Doing a quick test right now, fully charged its been off the battery for 20 mins and I'm showing 27% usage on the Android System, 10% on the Android OS and 15% of the screen and its down to 97% already.
Same thing happened to mine. Went to bed at 95%, killed all apps, empty ram, turn off data but left wifi on. Woke up 8 hours later and it was down to 17%. Unprecedented 10% hour drain. Usuallly it drains 3 -5 percent overnight. Same thing happened to wife's phone and she is on Sprint but she left wifi and data on. Uninstalled Google camera and Skype and notice it went away. Testing it again tonight.
Edit: Test it again last night. 4% drop in 8 hours. Woke up to 96% this morning. Hopefully that fixed the problem.
Update: Went to bed at 11:30 at 68% and woke up 7 hours later and battery is still showing 68%! Surf the web for 5 minutes before battery drop to 67%. Amazing standby battery drain. I had turn off wifi, bluetooth, and data before going to bed and killed all the apps. Usually this will cause a .5%/hour drain but it barely drain .5% in 7 hours this time!
