Day 2 (xlv, single frequency@1000)
Browsed the web for 2 hours,
played fheroes (w/ CD music) for another 2 hours,
installed and uninstalled several packages and fiddling with things for 1 hour,
then left on with wlan connection,
after 6 hours i turned on the screen and the battery had ~60% left. Not bad to me.
Also no obvious heat or warming on the battery.
Will keep playing and reporting back.
