Underclocking artemis, worth it?

[stead]

I've set tomtom to run at 175mhz using batterystatus, will this help battery life at all?

reason being is today the sun was heating up my car nicely, and my phone was running at 40c which i thought was a bit hot, so i thought i'd try running it a bit slower withtomtom open since its sits in the sun directly all day when using it, set it to 162mhz but noticed sometimes it just didn't seem smooth, set it to 175mhz, seems perfect!

Another side affect i've noticed, although i'm not sure if i have a faulty charger, but when the phone was set at the default 200mhz charged fine, after 15 minutes of driving with the phone clocked at 175mhz my charger stopped charging the phone, and i seemed to be able to smell faint electrical burning from the charger, would underclocking/overclocking affect charging?

also, does running it 25mhz slower have any impact on battery life? since my charger has now died wondering if it'l give any noticable gain in battery, just hoping it helps keep it cooler

Clocking does not effect the process of charging, only the time the battery lasts. When you connect your device to a charger and the battery is full, it won't get more charge from the charger, this is software regulated, so the battery stays full and the phone runs on AC power.

For your purpose i would check if the device is any cooler than it was with 200 mhz. I strongly doubt, that 25 mhz less CPU Clock have any major effect on Temperature or Battery life. If in your case your device runs longer and stays cooler, just leave it that way if you do not experience any performance problems, but i think you might as well clock it to 200 mhz again.
