Is the only difference between Droid Razr Maxx HD and the Droid Turbo the battery usage or are there more heavy duty differences as well? I am thinking about trading in my Maxx HD for a Turbo. I got three contracts up in my family and three upgrades with contracts. I haven't been on this site for a while and have had problems with my logon. I'm up and running and need some professional advice on the differences. I also use my droid for surfing the internet more than in the past as well as the camera. My Droid Razr Maxx HD has been outstanding. But if there are some serious advantages for a change, please let me know. Thank you most gratefully for your time and effort!
