To get an idea about the available battery life I put the AVATAR Mercury Ultrabook AVIU-145A2 in High Performance mode after a full charge and played back a 720p video in a loop. It lasted roughly four hours, which is a great performance and would yield a longer on-screen time under normal use. In terms of portability the AVATAR Mercury Ultrabook AVIU-145A2 weights about 3.9 pounds; not the lightest ultrabook out there but I still find it very comfortable to carry around. The aluminium body offers a good grip and is overall very nice to the touch. I actually managed to fit it in the ECBC Poseidon Messenger Bag K7202 that I reviewed a while back. The thin build of the Ultrabook made it possible to also fit the charger and some other stuff in the various pockets; not bad knowing that the bag is for 13" laptops!
