Asus Ion-Powered Eee PC 1201N Review
Battery Performance
As you'll see in the chart above, we notched 3 hours and 23 minutes of life with the screen on 50% brightness, Wi-Fi and Bluetooth flipped on with BatteryEater Pro running in the background in order to mimic "real-world" work going on. This test has proven accurate in actually simulating a reasonably heavy workload in order for us to give you a figure that you can bank on when using your rig on the go.
Around 3.5 hours on a dual-core machine with an Ion GPU isn't too bad, particularly when this was being "used" constantly by BEP. You could easily stretch that to 4-5 hours if you killed the wireless options or put it to Sleep every now and then while you took a break. Asus' 5 hour battery life figure is actually attainable on the Eee PC 1201N. Kudos!
