I installed Handcent and disabled the SMS notificatons, but in my task killer, the Messages is shown as working every once in a while, even though I never open it. Is there a way to completely remove the SMS application? So I keep reading about the battery issues and the SMS not letting the phone sleep. I am just wondering how do you know if the phone is sleeping? I lightly use my phone from about 6am and it lasts about 12 hours. By 6pm I have to plug it in.
