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 must make a big difference in battery drain. I never actually had any problems with the battery since I'm not a heavy user, and I always have the ability to charge my Q. I did this hack yesterday afternoon and by bedtime I was down to 2 bars whereas I normally have 3-4 still.
