Droid Turbo 2 not "turbo" charging

[Eliz0913]

For the past week or so, my Droid Turbo 2 will not turbo charge. It recognizes that a charger is connected, but since it won't do the "turbo-powered" charging, it actually loses battery while it's supposed to be "charging". I've tried 2 different turbo chargers and I've tested all 3 of my turbo chargers on my wife's phone. All 3 chargers work correctly, except when plugged into my Turbo 2. So, I guess my question is this: What is causing this, and how can it be fixed?
