Best battery life: iso-333MHz or UMD-222MHz

[Nicko01]

Yes, i know, no iso talk, but this is just for reference.
What would have a longer lasting battery? An ISO/CSO at 333MHz or a UMD at 222MHz?

I don't think it makes much of a difference? But I'd rather a umd at 222mhz as the umd is always spinning you see.....while on 333mhz it's going to constantly keep draining the battery at that rate.

[Nicko01]

well, the thing is, using a motor to spin the umd, moving the laser, and operating the laser would use more battery than running the psp at 333MHz.

222mhz will ALWAYS take less battery power.

[Nicko01]

... i know that.
what i'm asking is what takes more battery power, running a UMD or clocking the PSP to 333MHz.
The performance would be about the same i think.

I wouldn't be able to test this myself anyway because my UMD drive is broken.

[ICE]

iso at 333mhz would easily be my guess.

I think the iso 333mhz would actually drain more power - sony clocked the cpu at 222mhz for a one reason - battery life.
