Battery life excellent so far, 9 hours fairly constant use with 75% still left. It is very pocket friendly. Build quality is good but would guess it will not stand the amount of floor hits the MVP has. What's wrong with usb charging?
Update after 2 days of fairly heavy use.
It cannot keep up with a 7 month old, well used MVP2 regarding battery life.
It does, easily, last for a 7 hour day of quite heavy use.
It's smaller, lighter and more powerful than the MVP.
It's nowhere near as strong and would not stand a normal drop on the floor without some damage.
Can it replace your MVP?
Yes, but only if you have two of them.
