ok, tell me what you get.

i struggle to get more than 2 hours, before i have to plug it into the mains.

if i play music/videos, this gives me even less time.

I get about 4,5 hours if just using web browser and word processing in a power saving regime on Linux, which is the usual I do on the go.
Around 4h if music too.

I have Acer Aspire 5610
