yeah i wouldnt think so either but i changed everything back to default that has been mentioned in this thread and my battery still doesnt even last a day. I am about to do a master reset. would that fix all the registry edits??

a Master Reset will revert all registry edits/changes.

I have done both, grant I've done almost every hack for the Motorola Q9c, that's made it faster & sleeker. I'm a huge fan of Big's hacks, I've only had to Master Reset once, and that wasn't even about his hacks, Thanks Facade. Anyways I have done both of these hacks, I've tried both of them giving each one a full day of testing, running with everything I could throw at them, with Profile "0", I've experienced a more productive day, everything seems faster, on the other hand, my battery suffers, consistanly hot. But the performance increse is worth it, even if the phone does die. With the Threshold hack, I've experienced a longer battery life, 10 hours max, compared to a reg, of 8 hours with the ProfileType "0" hack. It did not make the battery run as hot, but was still rather warm. With default settings you get what you edit, in my eye's if you have a short term contract why not, 2 years hopefully nothing will happen. Default settings gave me a rather impressive 13 hours of aggressive use, was expecting alot less, but going from these hacks back, seemed to 'burn-in' the battery (using Motorola 3.7v BT61), computer overclocker's will understand this. But the performance suffered, I was consititanly yelling at my phone, wanting to switch back to the ProfileType "0" method.

Performance for the Q9c user - I would chose ProfileType "0"
Mid Performance for the Q9c user - I would chose Threshold hacks
For maximum battery life, but with low performance for the Q9c user - I would chose default settings.

Only one freeze, with the threshold hack, due to a Older Google Maps Application. Doesn't seem to freeze with Google's newest edition of Google Maps.

Hope this helps those of you Q9c hackers.

Change the value in Key "ProfileType" to 0.

Forces the CPU to 314 MHz. Survives a reboot fine. My guess is that IPM is a driver Motorola uses to control hardware power settings, and this directs the driver to stop CPU scaling, thereby defaulting the CPU to it's normal state of full power.

I was not satisfied with the auto CPU scaling so I poked around and eventually made this change. This area will also allow you to tweak the scaling threshold values if that is what you are into.

This edit, combined with changing the shell memory value to 96, and keeping a clean install are the only speed tweaks I use.

This registry key doesnt exist in my q9h. I'm using phm registry editor on an at&t branded Q9h global. any help would be much appreciated.

[fr4nk1yn]

That's because the 9h doesn't have them.

URGENT:
OP, what is the original value that you changed to '0'?!?!
I changed mine, but my battery is REALLY suffering. I need to change it back, but don't know what it's supposed to be....

PLEASE HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

On my Q9c, the ProfileType is default at "5."
