How is the battery life? Do you see any lag when using the phone? And do you think this phone will come to Virgin Mobile USA?
No lag per se, but it's not quite as responsive as high-end (dual-core) ICS phones. Battery life seems fine, should get a full day easily.
No idea about specific networks, but I wouldn't be surprised to see this on pre-paid or regional carriers.
I believe this are important questions:
1) How good is the keyboard? from 1 to 10, 10 being the highest mark. do you feel it is cramped?
2) How good is autocorrect? how do you think it fares when compared to swiftkey X ?
3) Does it come with headphones? if yes, how good are they? beats in there?
It's the standard Sense 4 keyboard. It's pretty good out of the box, but it doesn't learn the way Swiftkey does. Autocorrect does a good job, it works about as well as it does on the stock ICS keyboard. The keyboard doesn't feel too cramped, but obviously you've got less space than on a larger device. It's still perfectly usable though.
It comes with earphones, and they're the same crappy, generic HTC ones that ship with the One X and One S (not the urBeats/iBeats that came with the Rezound and Sensation XL). They're pretty bad, you probably won't want to use them. On the other hand, the One V still includes all the Beats software enhancements, so if you've got some decent in-ear earphones you'll be good to go.
