[tony1208]

had my x 3 days now...last night i passed out after my x was full charged...woke up 9 hrs later and it was at 40% battery what the heck ? so i looked at my running apps and they all were going ,all the stock apps ....esc the social network one. isnt the android system suppose to kill the apps if your not using them ??? the x doesn't seem to be doing that..so im thinking of buying advance task killer pro ...but im not sure.. gps ,bluetooth ,auto sycn all off,only widget i have is the wheather
