This ^^. I got one for a week just to play with it, and in an area where it's roaming on US Cellular at 1xrtt (2.5 G) I was getting well over a full day of HEAVY use. Heavy as in 3 email accounts and over 1000 emails a day, two twitter accounts, 3 news reader apps and all the normal things I do, syncing everything.
I also got over 60 hours standby time out of it.
The battery issues are all just LTE growing pains that you guinea pigs get to help fix. As a trade-off ya'll get grandfathered into an LTE unlimited plan and have the best device on Verizon (for now) to play with

Buy a spare battery and a stand alone wall charger and never look back.
