According to Twitter we are getting a tweaking.........
I am on the 3/5 Cookie 23542 and my battery life has been pretty good for the use I have put on it so far. Only thing I did was use NinjaDucks (thanks BTW) power saver cab and Service disablieng cabs to kill BT crap because I don't use any of that. Then I scaled the backlight to 40% and turned auto adjust back on. I flashed last night on full power and heavily used the device to sms, mms and left Opera open the whole time, for about 5 or 6 hours and then just a few texts off and on for another few hours, went to bed......6 hours later. I was at 30%. Not bad for what I put it through I don't think.
Thanks NRG!!
