My Droid 4 won't charge with the phone still powered on. I have had this happen a couple of times before. I would just turn it off at night and charge it, but not it will not charge at all while it is on. I listen to the radio quite a bit on my phone during the day and usually have to charge my phone a couple of times throughout the day. My work day starts at 4 am and I usually do not get home from my second job until around 10 pm. I usually charge it after about 6 hours. I usually plug it in and continue to listen to the radio. Any suggestions?
