Having just received my HD7 3 days ago, I am still getting used to it. However, I do have to charge at least twice a day compared to my WP6.5 by Samsung.
Welcome to my world of 1230mAh batteries. And with your larger 4.3" screen, I feel for you man. Nearly two full charges a day for me as well. A 2200mAh OEM extended battery would have been sweet. ****, Verizon made a 2150mAh for the Trophy.
