Well not issues, more like questions about it..
So, anyways, I was told that after rooting, I could vary my CPU usage that could, thus, increase battery life (or decrease it)...
Realistically, it did nothing. SetCPU, I mean. My friend gets an average of ~13 hours usage every day on a full charge. I take mine off the charger at 7am and the battery level is around 30-ish by the time 1pm comes, and I hardly touch it until 2:15.
I'm on the Motorola Droid, running FroYo and a 1250mHz kernel.
Default profile is 900mHz max, 250mHz min, CPU gov is ondemand.
