@eried I found this interesting table:

50g current consumption seems to be about 3x the 48gx's for idle and busy processor. I guess 4+ yrs after the fact, it's a little late. But someone should tell the tester that the backup batteries in his cards are bad. Current consumption is zero ( < 0.005ma) with the unit off if the card batteries are good.

@sbergman27 Never tested that. First releases were very buggy, I remember my 49g+ menu constantly flickering and not using all the screen because the cpu-emulation.

@eried It must have been one hell of a ROM bug. What's the milliamp draw of the 50g at idle and while running a processor intensive program?

[eried]

@sbergman27 You're right about the emulation but not about the power. Four rechargable AAA last 4-6 months in my 50g (now 1 year with low usage), early 'faulty' roms can make the hp to use more battery

@eried Functionally, the 50g is almost identical to the '93 vintage 48gx & '90 vintage 48sx. It runs on an ARM instead of Saturn processor. But the ARM is just running a Saturn hardware emulator in software. So it's about 3x faster than the 48gx, but eats batteries like they were going out of style. I change the batteries in my 48gx every few months. I've seen mailing lists posts from 50g owners complaining that the 49g+ & 50g couldn't make it through a single exam on a set of batteries.
