HP’s TC4400 – 16 hours of battery life

Warner Crocker took a longer look at the TC4400 specs and noticed some great specs on the battery. Hmm… I could live with 16 hours of battery life.


Bump each of those hours down by a 1 to 2 hours and I think you probably have a more realistic battery expectations.
