What's the average or normal battery life for the stock battery on the Droid2? The only smartphone I have to use as a baseline is my issued BlackBerry 8820, which will last 1 week on a single charge with low usage (email and that's it). So far, I've gotten only about 2-3 days max out of my Droid2, but today (within a week of getting the phone) is the first day I ran it down to the point the phone turned off by itself. I charged it to 100% within 1-2 hours and am now running it again. Can I get 1 week on a single charge?
