This is a joke of a review.
Acer dramatically increased the battery capacity of the Aspire S7 from 35Wh up to 46Wh. Despite the higher capacity battery there’s no increase in weight.
And yet only ONE of the battery benchmarks accounts for battery life/WH.
They are comparing a USED ultrabook from august 2012 to brand new factory released demo. If you look at any rough battery life expectancy charts, the old S7 should have lost roughly 30% of its battery already. Its also very rare that the only thing changed in the laptop was a new CPU and motherboard, a different model SSD can also make a huge difference, they can idle from 0.03 Watts up to 1.30 Watts. There was NO mention of LCD screen testing, a 10% decrease in brightness on the new laptop could easily result in 5% additional battery.
If youre going to review the system do it right. Dont follow anadtechs sloppy testing. There is a lot of missing/hidden information here that can easily account for the battery life gains.Edited by s-x - 6/9/13 at 8:07am
