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.

ehyz guys, i was wondering about the 4.3 JWR and JSS roms.
im planning to switch from 4.2.2  to 4.3 soon > PA rom (waiting till everything ok oni.)

i got my 4.3 stock image here
but this stock image is for the 4.3 JWR.

my noob question is how to get the JSS rom? or just flash PA's JSS Rom on top after flashing stock?

Ok, I've downloaded it. And then what?

just weird i discovered that android decice manager was appeared in my phone device admin, but how to keep track on my phone?? there must be web interface to monitor my phone right. any one knows this?

These guys can help you out, I contacted them before and they do offer custom casings for our N4. 

That was with 4.2.2. Will try benchmark 4.3 after I finish tweaking it. Right now, only undervolting at around -175 and overclock to 1.8ghz. Got a feeling 4.3 will be a little better due to more efficient merge and arrange rendering.

Ok, I've downloaded it. And then what?

Finally, couldn't really resist the 'lust'  from 4.3. Flashed everything and started clean with rasbeanjelly jss. Smooth and no hiccup at all. Flashed the radio too and let's see how's the battery now.
