Android is at 20% on my system. I am am at 30% battery after 12 hours plus non-LTE usage. I think the main thing to worry about is whether or not your phone is awake when your screen is off. Also, Juice Defender seemed to cause conflicts, and my Razr has been better without it.
Yea It's 18% usage for Android OS for me after 15 hours (I'm at 15% battery left). I believe it's high compared to my Xperia X10 2.3.4.. I am not sure this is normal. Maybe the smart actions are included in Android OS and it ends up eating more juice than saving some? lol. Else maybe some expert could explain us why it is that high.. :P I think techfan2011 is right, need to worry about if the phone is awake or not..
