I gave QuickClock a shot and it took a lot of the hastle out of configuring my DX. Lower VSEL's to just above tolerance and that's a huge battery saver right there. I have my device underclocked to 800mhz for every day use and it runs absolutely smooth. I very rarely ever have to turn up the speed on my processor. Some games do require faster processing speeds but not many, and for that I usually put my phone in its charging dock and overclock to 1100mhz to 1300mhz. The only thing I have autosync is gmail, and I even turn that off if I forget my spare battery or something. I've also taken a liking to JuiceDefender and have all data services turned off when my phone is in sleep mode. I'm also running Darkslide and I absolutely love it. Moral of the story is, I bought my spare battery when I was running stock settings. Now my spare is pretty much for my wife's DX since she's still running stock. Amazing how just a few things can make such a huge difference.
