Guys, for the wired chargers, we are not talking about the STATED MAXIMUM OUTPUT here, we are talking about the output IN PRACTICE. Most chargers are rated for instantaneous output (it can output 1A or 2A or whatever is listed on the charger, but only for a millisecond, then the rate will fall off).
Please use the app and let me know what your rates for wired charging are (not that the rates fall off when the device is charged more than 75%, so try to test when the charge is lower than that). I bet the rate you find will be lower than 800mA, but if this is not the case, I am curous on the charger and cable that you use.
As for the wireless charger, I know it is very very bad, am trying to return it.
