I have been using my DX for a couple of weeks and have observed the battery will stay charged for a long time if I don't do much. Talking on the phone, standby, texting are reasonable but if I'm on the web of using navigation it goes down pretty fast. Not much I can do about this from what I have read but I have a couple of questions.
Is there a stronger battery available for the DX yet? If so is it thicker needing a different battery cover? Who sells it? How much better is it?
Also on phones in the past I had always had really good battery charge life and had always used the practice of letting the phone die every once and a while and giving it a complete powered off charge. I know you aren't supposed to need to do this with current batteries but it seemed to work for me. The X wants to be charged when it gets to 30% and I seem to have read somewhere that you weren't supposed to let it get really low. So what is the real story?
