Hi, i currently use my old android phone's charger to charge my motion every night. It charges and works fine. Yesterday i took the charger that came with the motion and charged it for a bit in school. When i came home that night i plugged my motion in the other charger and went to bed. When i woke up this morning, my phone was at 20% battery with the charging indication in full swing. I recalled that i plugged the phone in at 53% battery. I have no clue how this is happening. Also, theres a slight difference in the amps of the two chargers. The old phone's one is 0.3 amps (i think) and the motion's charger is 0.7 amps. I dont know if that has anything to do with the problem.
