One of the first things I learned when I had my Incredible was to pay no attention to the bars for signal reading. They really didn't mean much of anything. I always had 0-1 bar in my basement, yet had crystal clear call quality and 3G. Go figure!
Also, little things can make a huge difference in your battery life. If you're not using the Sense stock, weather and news apps, turn off the sync. They are defaulted to be on. Try turning your screen brightness down. I always had my Inc, and currently have my Thunderbolt, below 50 percent and I can see just fine. Check your sync time settings on different apps you run. Some will be defaulted to sync like every five minutes, which is not always necessary. Doing just a few little things like that will make a major improvement. I've never had battery issues, so i guess it really does work!
Just a few things off the top of my head. I hope you enjoy your new Incredible!
Oh, as far as the green battery full light. If you charge your phone until the green light comes on, then turn the phone off, the amber light will return. You'll be able to charge for a while longer to get an actual full charge. For whatever reason, the full charge doesn't happen when the phone is on. The alternative is to just charge the phone with it off the whole time, but that's not always an option.
I always charge my phones overnight, so I stick to a charging schedule. It works for me, and as long as I follow through every day, I don't have any issues. Even if my phone is say at 40 percent left, I still put it on the charger at night. If I don't, it gets cranky.
