I am on Cm 7 a7 and was having similar problems. So i got a new battery just today evening. i hav put it in and m using it(haven't charged it yet) so that i can completely drain it and charge it properly.
Do I need to calibrate the battery after full charge? I'm using CM 1.3 HV kernel. what sort of battery life are u ppl getting? I do not want to use set cpu, so i have just set max cpu freq to 800 and governor to lagfree in cynogenmod performance settings. will that do?
about calibration...well you can do it...but even without calibration it should calibrate by itself after 3-4 full charge and discharge cycles...setcpu profiles can help u to gain some more battery life too:P
