That sounds a bit low.

Not that I've seen longer life on mine, but I use mine a lot.  A day or
two ago it survived from 8 AM to 2 PM while online using 3G (and later
WiFi), with almost constant web browsing, email checking, note taking
and GPS usage.  I started charging it before I saw the 'low battery'
warning.

Have you tried disabling facebook and forecast?

Have you tried running powertop in an xterm and looking at the output?
