After not even a month of use, the battery life is not even 1.5 times that my tired old battery .. I can make it hold one and a half (sometimes more) without GPS, WIFi and without with Data (3G, H + ...) partially cut, turning off the laptop during the night and leaving the mainly in sleep mode (some call, a lot of SMS). In short bit more about this. I played in the coup attempt, but I lost.
