gonna share a little after using L920 for 24 hours.
1st thing first: Battery life is like....

but since its only one day old i guess i should give some time before i really go into the battery life.
on wifi for 3-4 hours makan less then 10%, use 3G for 10 mins makan 6%? lolz....
2nd thing: OS rocks @ss (well at least for my usage) normal use including fb, whatsapp, and occasionally email.
love the smoothness of the UI. went crazy over the tiles, was like messing with it and sliding it all four direction because its freaking smooth!!!!
i miss this since when i first bought SE xperia Arc S upgrade to Ice Cream Sandwich lag until i wan throw phone =.=
Have yet to test the camera. maybe after work. cant wait for the wireless charging plate.

Note: oh wanna ask if you guys turn your NFC on the whole time or off?
and also got addicted to Angry Birds Star Wars

<-- a must buy game
turned off, bcos i have no use of it for now.... but probably will leave it on if needed in the future
