I am using the same car charger that my droid x had but today i tried to charge my bionic at 1030 am since it was on like 30% and at 330 pm, it was only at 60% ? really 5 hrs for only 30% is this right? keep in mind i am still using the phone while charging mostaly streaming radio online but my droid x was charged in like 2-3 hrs fully.
