I've only had my DX for about a month now and am still a noob when it comes to overclocking/undervolting my DX. I downloaded QuickClock Advanced and calibrated to be on the safe side. Should I stick with the values given for the batter saver/overclock profiles or is there room to stray a bit? I'm hoping to get the best battery life from my device, it seems that battery life has decreased since the jump from 1.0 to 1.5.
