The OEM charger does the turbo charge properly. I've only used it twice. I use a different charger at home at night and it charges fine. When I plug it in to any of the chargers in our trucks, it says it's charging (not Turbo). On a "typical" day (how many days have I actually had this), I start out with 100% at 5 AM and plug back in at bedtime which is around 10 PM with ~ 30% battery. I use my phone quite a bit for calls, texts, facebook, linkedin, and tapatalk, so I consider this a fair drain on the battery. What I experienced over the weekend troubled me. I can't not have a phone with a charge. I do have my little battery pack I used while instructing, so that was a huge help, and can continue with that setup if need be, but I would think the phone could handle the use I was throwing at it. My Bionic, with it's pathetic battery, and my Maxx could handle it. Granted, with the previous phones, I was able to deactivate email synching when I knew I needed to conserve battery.
