I just did the 3g hack and noticed incredible battery life loss. So I restored stock nandroid before reflashing anglerom. My batt was @ 40% when I restored nandroid, but when I rebooted my batt was @ 80%. So I went ahead and reflashed angelrom and rebooted and batt was still @ 80%. I do have an extended batt, 2200mAh.
Also, this morning I was having issues with streaming videos, I could only watch one then would have to reboot the phone to watch another. I use dolphinHD blacked out, not sure if that could be an issue. No problems since reflashing rom and theme(black out 10%).
If anyone cares, I got better quad scores when no oc apps installed than with them. 2200 or better consistently, with stagefright enabled.
