Thank you for testing this. That seems pretty similar to what Sentaro21 gets with his other app ftune:

23mA without overclocking on the SH4A

Pretty interesting to note as well that the SH3 version of the fx-9860GII draws nearly twice the current at 43mA at stock speeds. Maybe Casio just copied the old SH3 fx-9860GII power consumption figures for the newer SH4A version.

In any case it seems pretty hard to hit 0.7W. How would you get close to this sort of power consumption?

It's the same situation similir to the Windows, when I turn the PC off (or sleep or hibernate) during some activity (e.g.video conversion), the activity or result is lost.

I was more worried about the "Main Memory" files and the Run-Matrix history in RAM being backed up; and it sounds like it is based on your input...I've now impulse purchased a fx-CG50 (please don't tell me it actually forgot your files after all now Big Grin ).

I would of liked to get the fx-9860GII-2, but the price is pretty much the same as the fx-CG50, so it seems worthwhile going with the fx-CG50 for the additional OS features (though mostly minor, for example; integrating between roots in graphing mode automatically), Python and being able to make use of the xcas port.

I'm still curious though as to exactly what stuff is retained on the SRAM versions (CG-20/10/9860GII) vs the SDRAM fx-CG50.
