Asus Ion 2-Powered Eee PC 1201PN Review
Battery Performance
We were able to squeeze out just under four hours in our real-world BatteryEater Pro test, which runs a graphical application in the background to simulate average desktop use and Web surfing while having the brightness set at 60%.
That's nowhere near 7 hours. Of course, if you cranked the brightness way down and barely used your machine at all, you may get it to stay alive for 7 hours, but in real-world use, expect a lot closer to 3-4 hours. Had we ran any serious multi-media, the score would've certainly stooped closer to 3 hours on a full charge. The benefit is that there's no "battery bulge" with the included 6-cell, but an extended 9-cell for even longer use may interest some. Also, note we score another 35 minutes of battery life above and beyond the previous generation Asus 1201N. Not too shabby actually but we were looking for a bit more..
