hi,

just wanted to know if there is any way to increase the battery life on the n900. mine last for around 5-6hrs...max 8 and then dies. is it a hardware prob or there is a better kind of battery for it. also, if i go to xterm and enter the comman: sudo root, it wants a password. what exactly is it? one last question . my rootfs is showing as 55mb free and the rest is used up.how do i free more rootfs memory. will it cause considerable probs if its full? and what is it???

loads of questions..but pls do ans.
thanks in advance
:-)
