With rechargeables a figure of 60-70% of this is probably more realistic.  Even then you'll probably need to turn the screen brightness down to achieve this.

IMHO (again with the Oregon), there are only two useful brightness
settings: minimum, and off. In the dark, the minimum is enough. If
there is ambient light, then even maximum doesn't make much difference
so you might as well turn it off.

Probably a bit OT, sorry.
