I suggest that
    mount -o remount,ro   /
(remounting the root filesystem read-only)
and doing likewise with other partitions would be a good idea!

If you care about measuring the lifetime, plug in a usb-memory key
(a filesystem you don't care about), and run:
	while : ; do
		uptime >  lifetime.log
		date >> lifetime.log
		sync
		sleep 2
	done

Then you can flatten the battery at a faster rate by running, say 
glxgears in full-screen (uses both CPU and graphics card).
