So I have a TU running CTMod, and its obviously rooted. JuiceDefender is installed, and no task manager. With nonstop internet use on 3G, I get about an hour. With nonstop internet use on WiFi, its about 2 hours if I'm lucky. GPS is off. With light use, it usually last 4 hours, 5 if its a good day. Battery use is mostly spend on system, which is 80+. I tried calibrating multiple times, sometime it will die as soon as its off the charger, and sometimes it dies when it isnt even close to 0%. Any help is appreciated.
