If you read good reviews you see battery times vary from about 6 to 1 to as high as 10 to 1 when a laptop is on power conservation versus full load. So when folk want 6 hours of battery time we have to ramp that up by 2 to 10 times to hit the 6 hours under load.

Lesson? Don't count on battery time. Besides with 300 cycle rated batteries you might be replacing a battery every year to keep the times up as good as new.

For me, I'll take the Lenovo Y50 for dev work.
