I dont wanna clutter the thread with argument like responses to your sarcasm, but since you seem to be in great disbelief - I'll respond to few points you made:

1. Antutu scores is a combined measurement of many benchmarks, which include CPU, IO, memory, various graphics performance parameters etc'. Not all of these are used frequently during normal phone's operation. Therefore Antutu score may be greatly impacted by a benchmark, which in reality uses only 2% of the CPU cycles, or vise versa. Speaking from experience and coming from years of using other android phones I did see things like IO schedulers, for example, give noticeable boost to performance, which may not be visible using a benchmark tool, for the reasons I just mentioned.

2. Battery drain isn't going to be reduced by half by using a smart algorithm, such as hybrid adaptive voltage scaling (HAVS), but it might achieve results close to that, if combined with trickle charging mod, which charges your battery to a full, not fake 100%, and can keep your battery at 100% charge for nearly an hour after it's unplugged and phone being used.

If you want to get autographs from people, who made those amazing kernel mods possible - you can start with netarchy , toastcfh and some other devs from Team Win gang, who made amazing things like hardware acceleration based HDMI mirroring possible

DONATE TO ME
Long weekend.. working on a new build now

HAVS is actually already built into the stock system. It scales according to demand from 3 separate units (the memory/bus subsystem, the GPU, and the CPU(s) )

The voltages you can set in system tuner/fauxclock/etc. only apply to the CPUs, once my app is out you'll be able to adjust GPU and L2 voltages/speeds as well.

The other governors etc. are coming shortly.. hopefully tonight
Support my work! The more phones I can get my hands on the more ROM goodness I can churn out. Like BUTTAH

It's a blessing to have you onboard. Just bought you a beer: 3UH01598G2087792E

Next time maybe I'll take that 1 hour drive to OC and buy you one in person

Awesome work Da_G! So the new kernel will enable Voltage Control options for Antutu's CPU Master Pro?

Da_g so if havs is already implemented in the stock kernel, then if we statically undervolt the cpu does that mean it won't use havs? and then would it be better to not undervolt at all or does undervolting just limit the max voltage that havs will use?

thanx

Great question, I was wondering the same thing what would happen if you use an app like Antutu CPU Master to force static undervolting on kernel with HAVS. There is no doubt in my mind HAVS is better than static undervolting for a number of reasons, with stability being #1, but I'm also curious to know how such conflict would be handled.

Another thing I did, was install adw ex as my launcher. any ideas, advice?

I restored to stock for now.

Thanks.
Are you sure you didn't mess with voltage settings and do something wrong there? Happened to me one time and started acting the same way you described yours. Anyway good luck
