[Defy General] andycore:
Reporting in with a different approach. I'm using a combination of Aero Control and the V6 Supercharger. Wanted to share my configuration, in case it's useful to someone else.

Aero Control

CPU Settings

Governor: Performance - Max freq: 1200MHz - Min freq: 400MHz.

OC Settings:

1200MHz/61

900MHz/53

600MHz/43

400MHz/30 (These lower two speeds I haven't played around with to see how low the vsel can go, will experiment in future, somewhat irrelevant on the Performance governor anyway)

Memory Settings

Dynamic FSync is ON

Writeback Control is ON

Low Memory Option is ON

Swappiness is 30

IO Scheduler is Deadline

(I actually want to set the IO Scheduler to "noop", however, it tells me there are no settings available and reverts to Deadline automatically.)

Greenify

(Get it here)

Basically all non-essential apps are greenified. Location apps (such as Foursquare and Maps), and anything that doesn't require push notifications has been set to hibernate. Not sure whether this is having any effect, but it certainly cuts down on multitasking time between apps as they hibernate.

V6 Supercharger

(Get it here)

Only at 50% Supercharged, so it can be optimised further if required. I'm getting pretty good performance out of the phone as it is, though, but will see how it goes.

Configured with option 10, "Quick V6 Cust-OOMizer". Minfree values are 8, 12, 52, 62, 71, 81 MB.

Configured the following options, all else are set to "OFF":

Kernel and Virtual Memory tricks were ignored (status: Disco Dance), didn't want to interfere with Aero Control in any way.

Misc & SD Card tweaks are ON.

3G TurboCharger is ON.

Engine Flush-O-Matic is configured to run every 6 hours.

Auto zipalign ("Fix Alignment on Boot") is ON.

Services.jar has not been patched, the app can only auto-patch on ICS/JB.

Others

HWA is OFF for all apps except SystemUI, Launcher, Camera, com.android.incallui (but not phone or dialer) and a handful of personal apps that lose performance without HWA.

Will report in with battery life at the end of the day, so far it has been off charge since 7:30 AM (It is now 11:15AM) and I've lost 40% battery -- however this is with

1hr+ of screen-on time

while training (I use a workout logging app) along with playing music over bluetooth headphones.

(O.T. On a side note, I'm finding that using Apollo + BT headphones is somewhat sketchy (stuttering music), can anybody recommend a light-weight music app?)

EDIT: Battery Results

Note: I'll be posting new battery stats at the end of the day. I realised this morning that I had the screen brightness set to maximum yesterday, set it to auto today and only lost 15% during my training session (instead of 40% like yesterday).

After being on battery from about 7:30am (and an accidental 20 minutes or so charging in the car when I forgot I was supposed to *not* be charging it) I was down to 6% at 5:30pm.

To be fair though, the phone saw pretty heavy use (i.e. compass for work, much moreso than usual), and the battery performance is just about on par with my Droid 4. The performance gains are noticeable, and I have ample opportunity to plug the phone in through the day in most cases, so I find this acceptable. I'll configure a low power profile at a later date I think, for those times where I need it to just be a basic phone for an extended period of time.
