I have had my Neon II for a few weeks, and I am having trouble with the battery, I have to charge it frequently. It seems like it is very often, especially when the info on the phone indicates 4 hours talk, 11 hours standby. I use my phone as needed, it is not hooked to my ear. Is there a setting that I can adjust or have adjusted to have a longer battery life? Or is there some way to find out what is causing my battery to drain so frequently?
