Thanks springfall. Those r some of the test that can found, and can't find any test with 4.0.4. That's why i m here to find out from actual users.
Pls give me more reasons to grab myself a nexus.

I would be worried if i can't get over a day with my battery. But i m not a heavy user. Maybe moderate use.
30 min calls, some sms, maybe a 30-40 min internet ?
Springfall, responding to your edited post above,
I m not sure how to read the screen capture by mikeee.
It says, 2% battery left > this i understand
It says, use details > screen = 56%. What does this mean?
Time on of 4 n half hours is referring to device on? or screen on?
I think 4 n half hours is device on. And screen on consumed 56% of the battery which equal to 151 min (2 n half hour) screen ON time. This is what i understand from the screen shot by mikeeee
So, that means that 3 hours of screen on with 3g or maybe wifi is about right from gsmarena test isn't it?

The remaining of he 44% of the 98% comprises of other stuffs like android os, apps, mobile, wifi bla bla bla (everything else that consume power)
