it's actually not too surprising. According to the power consumption analysis we got for the glamo3372 (it's in /space/docs internally), there should be about 60mW difference. Since we run the glamo at even higher clock rate, our absolute power consumption (and thus the gains of disabling parts) is going down. I think the major point is not actually the lack of having to generate the LCM signal, but the 100% reduction in glamo-SDRAM use. Screen refresh of 640x480 at 60Hz (or whatever we use these days) puts a very high constant load on the SDRAM.. > Just to be clear these were already all down in suspend, these new savings > come in the case where you're not in suspend but the display is "off". Yes. And once people start to use their GTA02s for something else than just a regular phone (i.e. run actual applications for GPS data logging, music players or whatever other creative things that 'openmoko is all about'), this 'display off but cpu running' state will be much more predominant than today, where you juts simply don't have that many of those applications...
