The Metro dc charger for $20.00 shows it charges reverse, in fifteen minutes you go from 70% to 15% charge, unplug from dc and plug into ac and it shows 70% charge again immediately. This happens on my tap out and my sons ascend. I took it back to the store, he replaced it with another, does the same. We know a battery can't go from 10-70% charge in a couple minutes, the phone is confused by the dc charger. Anyone else notice this?
