I have reviewed every battery life thread. My battery life is okay, not horrible. But, with extremely light use, I can only get about 12 hours. The largest percentage of use always shows 'idle'. Can anyone give me some pointers about how to extend it? Are there any basic things I can do? I followed the directions about CDMA and think (hope) I did it right. Unfortunately, I am not very technologically minded. I don't understand most of what is posted here. I can make a call, answer a call, download apps, send a text message and check email. That's about it.
