I captured this while I was on stock 4.3. Even without undervolting, the battery usage is impressive.

How long for the SOT?

my usual battery usage is around 5 days with 1hr SOT on 4.3
it used to be 3 days with 1hr SOT with 4.2.2

very little usage on my phone while most of the time i and in front of my desktop

nice. 5 days on low usage is almost matching the Nokia era 

seem like 4.3 has even lower power consumption in idle...

Hi, I wanna upgrade my lousy galaxy w to nexus 4, any bro/sis here wanna let go their pre-owned unit, can direct pm me ya, confirm/serious buyer here

Why all so proud of battery life when u barely use ur phone? BTW I think u feel that battery life is better coz u did a reset.. If u reset 4.2 also the battery would be the same.. My guess la

I agree. Like the first poster in this page has 33% on idle which means he don't use his phone at all. What's the point even if the battery cab last for years?

this is 1 common misconception. reset your phone will not calibrate the battery. to calibrate you need to drain it.

my battery life was even better when i was in 4.2.2 because I undervolting at -175.

so, your guess is wrong.
there are many ways to read a phone battery status. high idle and low battery usage = low leakage, low wakelock, etc. i do benchmark my phone in high usage too. check out my 6 hour SOT in my siggy.
