The thumb version has a gconf key, /apps/osso/status-area-applet-battery/use_design_capacity
I'm still worried by the known issues. Premature shutdown: so is it possible to calibrate in any way? If not using the design capacity, won't it cause insane results?
And the wiki states that any programs using the BME replacement break after 32 cycles after last calibration. The premature shutdown issue makes it more severe, doesn't it?
