I have had my HTC 10 since June. It charged beautifully and held a charge longer than any phone I have had. Starting 2 days ago it started to take longer to charge. Tonight I placed it on the quick charge at 56%. 4 hours later without being used while charging it is at 85%. I do not leave it on the charger after it is fully charged. I usually wait a little long to place it on the charger but I was hoping to get it to 100% before I went to bed. I won't leave it plugged in over night and I use it for music to sleep to and an alarm. It has gone from the quickest charger ever to the slowest. Anyone else experiencing this and any suggestions?
