    Not exactly sure you would undervolt the battery, but undervolting the CPU would save battery life.

    Sounds like a good way to counter the cm7 battery leeching, I have looked around and there are plenty of kernels for other phones that support undervolting.

    If I knew anything about android kernels I would be looking into it. Hopefully this peaks reppards interest...

    I know what he was refereing to :p

    and as for the battery, the wifi is the culprit for your battery drain.

    undervolting/overvolting the cpu, and yes it is possible to do this, it would be a kernel modification. you want to use the least amount of voltage for the cpu, so for those of use with failing overclock speed over 729, adding more voltage may overcome our limits ... or maybe not.

    three major factors in clockspeed and stability; Frontside bus, Mulitiplier, and voltage

    just had a flashback of overclocking my AMD rigs. My last was an Athlon X2 64 @ 3 GHz. I built it to fold, and had it competing admirably against some Intels on the team.

    I ended up having to scale it back to 2.99 GHz (*rolls eyes*) to prevent the northbridge from overheating on the 3rd day of full-throttle after a cold start.

    That system's RAM (DDR2-800 overclocked of course) and the CPU were liquid-cooled. It had a variable air-flow 120x120 cm radiator on the back of the case, which fed out to a 120x240 cm radiator a few feet away. It kept the room a constant 80 degrees. :)

    Good times.

    LOL good grief. Exactly. That's when you go buy a window unit and keep the vents aimed constantly at the thing, thermostat set at the coldest.

    When you overclock and require drastic setups like that, do you really ever notice a worthwhile usable difference in speed of various tasks?

    in benchmarks... maybe some gaming.... but I don't think i ever got my internets any better cuz of the computer being pushed to the edge lol.... and buying new hardware when some fails(but I need it cuz it broke!)

    i think it's more "why not?"
