Switching over from Nexus 4 to NEXUS 5 is awesome.
Phone was switched on from 7am to 3.30pm
(for weekday = 80% batt is remaining on LTE.
for weekends with wifi 85% remains)
Unbelievable. (Stock - not rooted)
But waiting for the latest Kit Kat update patch - now on KRT16M

hahahaha 7am to 5.15pm SOT 46m 5s 75% balance on Batt

NO WAY LG Msia can beat this price ($1555) when it is launched officially (god knows when!).
Looks like AP set price has more potential for downside to another lower price in due time

BTW I received 4.4.2 update for Nexus 10 but not on the N5 (don't intend to root atm)
