I enabled smartreflex on both vdd1 and vdd2. I read somewhere if you enable them the reverse order, your suppose to more battery life, but i didnt find that to be so.

One of the reasons why Nokia didnt activate it by default is because it sometimes makes the N900 unstable. By unstable I mean it results in frequent resets. In my experience, my N900 works perfect.

Battery life for a device is pinnacle to its usage and success. I dont think much attention is directed toward that field, but it should. I wish i knew more terminal commands in reference to SMART REFLEX.
