A little bit more , but has a bigger drive , and I find Acer`s are quite good on battery life , I notice the HP doesn`t mention that ... although it does say it`s a 6 cell Li-On
Just rummaged a bit more and there is a claimed 5 hour unplugged battery life , but that will be tested with everything off . I turned a lot of my features off and didn`t notice much difference in the look and operation , battery life went up a tad .
