Laptop/Notebook computers and their cheaper budget Netbook cousins may all look quite similar but one feature which varies a heck of a lot is the manufacturers claimed battery life which can be anywhere from 2 hours to 11 hours+
The best Notebook/Laptop computers should be able to pass the “acid test” of being used all day with the confidence that you won’t have to scramble to find the power charger cable and a powerpoint to recharge the battery every 3-4 hours.
ASUS claims that the 1101HA has upto 11 hours battery life. However keep in mind when manufacturers quote notebook computer battery life it’s usually under very specific conditions with the screen brightness turned down, WiFI access off and the computer being used for light tasks, not playing video, downloading/uploading from the internet etc.
Impressively the 1101HA displayed a 10% battery warning after being on for 9 hours and 5minutes. During this time I was connected to the shared conference internet connection and used the laptop to type notes and upload lots of photos to Flickr from my SDHC camera card.
From experience if you’re in the market for a notebook/laptop computer I would suggest taking the claimed battery life and assuming that it actually lasts about 2/3rs (66%) as long eg: 6 hours claimed = 4 hours in reality. From testing the 1101HA it looks like ASUS notebook/laptop computers can be expected to last closer to 80% of claimed battery life.
