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.

Unless I'm flat out blind, after reading through the entire article three times, there was absolutely NO mention that they benched a USED IB ultrabook in a comparison to the Acer Asipre S7 second generation. So I'd take a gander your lovely schpeal is quite false unless you feel free to actually show exactly what I'm missing.

What? That battery life is amazing in that small form factor. I think this is great. Performance was fine for what that form factor was meant to do and battery life is what was lacking and they made HUGE strides on it.

I recommend you read the article, because it was listed in the battery life section for both charts:

For the PCMark 8 battery life, the normalized tabs are what you should be focusing on

For the web browsing section, literally the only paragraph underneath the graph:
Quote:
The new S7 delivers over 2x the battery life of the old model. Normalizing for battery capacity, the improvement due to Haswell is 57.5%. These results track perfectly with what we saw in PCMark 8. Workloads with greater idle time will show the biggest improvement in battery life thanks to Haswell ULT.

However, your other two points are very salient. While this certainly shows more that the new s7 has a much better battery life then the old s7, it doesn't really indicate how much better haswell is at energy consumption without controlling literally every other variable (nits, ssd, etc).

This is why I am holding off. I want the 13 inch pro with retina display.

Also, I think it should be mentioned that the s7 had horrible battery life to begin with. So any improvement there would seem like a miracle.
