Ok guys, thank you for your replies. Yes, my english sucks so often i miss something reading 3ds. I know battery patch is not developed by Pali, it was my just 2 cents about it. In reply to Pali, i'm already using a not default profile, to undervolt my phone. I'm currently running an ULV profile without no stability issues. I did different test using the phone at 600, 720, 805 and 850 MHz too, with no significative differences in battery drain. Is still higher than with the stock kernel. I also reflashed my phone, to have a fresh and clean installation for the PK, but the problem are still unsolved. The thing that, more than other, sound me weird, is the time needed to charge the battery: 2hrs, sometimes less too, when with the default kernel is longer, almost 3 hrs or more. Obviously, i tested a second battery too, with the same results. In addition, i daily use Cony to monitor process in background, there is not something wrong running in background. It just seems that my battery is recognized with less capacity than usual. No one of you noticed the same problem? d!
