M9 Very Slow Charging Even With Quick Charge 2.0 Chargers


I have a continuing problem with very slow charging even with Quick Charge 2.0 chargers. For example last night I had the M9 plugged into a fast charger for over 12 hrs and it went from 5% battery to 87%.   I checked  the Settings - Battery usage history - and it displays "NO APPLICATIONS FOUND" - very strange...

Something is very wrong. I have multiple 2 amp and quick chargers all with poor charging times. I have tried each of these:

The Ampere app displays varying charger power from 15 mA to 880 mA so I don't think it is accurate.

Testing with multiple chargers point to the problem in the M9. This is maddening. Seriously considering returning the M9.

Any feedback?
