I just got my Dinc2 and I want to do whatever I can to obtain the best battery life. So I am following the directions which say "It's important to fully charge the battery before turning on your wireless device" written under Powering You Phone On For The First Time in the instruction booklet. However, I don't see anything in the booklet that says when it is fully charged. As of now I just see an orange light with the phone plugged in but still off, does this change? Thanks.
