OT: Samsung Galaxy Centura update

I found that there is a 3rd party kernel and ROM image available for this phone. Rooting the phone and installing the kernel allows the phone to be overclocked - the default setting for the ARMv7 based single-core SOC as was mentioned here is a maximum of 800 MHz, which apparently will be throttled as low as 300 Mhz depending on useage.

With the overclocking application, the processor core can be set to a max of 1300 MHz, and a minimum clock of 600 MHz. It's not perfect, but these settings make for a much more snappy and pleasant experience using the Android 4.04 OS on this device.

It sure would be nice if it had a gig of ram instead of just 512 megs, however.

go ahead and do it, tell us how that over heated processor works in the phone later.. Don't you think if it could operate at that speed on that phone with out issues, they would of done it?

Battery life issue.

I think there are quite a few reasons that a manufacturer might decide to underclock a phone's processor that don't have anything to do directly with heat dissipation.

The phone will be uncomfortable to hand hold long before the CPU itself suffers heat stress sufficient to cause operational failure.

Not necessarily. Sometimes the only difference between a faster part and a slower one is the official maximum speed that it runs at.

The problem will be that CPU clock speed and battery life are inversely proportional so instead of a smart phone with a short battery life he will have one with an annoyingly short battery life. To some extent it would make sense to have it clocked as low as possible when nearly idle. Phone CPUs typically spend a lot of time idling.

That works OK in theory - the problem is that it often seems like it takes a dreadfully long time for it to filter down from the OS to the hardware level that a CPU-intensive task has begun, and so you're sitting there waiting for the processor to realize that it's go-time and spool up to the higher clock rate.
