To test the battery today we put the machine through three sets of real world situations.
One as a media movie lover on the move, a person wanting to watch HD media on a train journey or bus with two thirds screen brightness (any less and quality suffers).
Secondly as a business man, using the machine for productivity with wireless enabled and balanced power settings with a mid way (around half) brightness setting.
Thirdly as a gamer on the move, with the nVidia graphics card fully active and screen brightness up high.
We were very impressed with the battery life of this machine as it managed to last for over 5 hours under light conditions. When watching media, this dropped to around 3 hours and 50 minutes. The capable battery life will certainly appeal to a wide audience.
