I am new to Android, just bought a Huawei Prism with Android 2.3.6. I'm on a prepaid plan & can only talk and message. The battery life is terrible and I have wifi, gps & bluetooth turned off. Is there an android app I can download that will turn off, or permanently disable, all the apps that I do not want running when I power on rather than have to turn each one off manually. Thanks in advance.
