Well, I can't break ~950ma on the Samsung OEM charger with my S7 Edge, and not more than about 1050ma on a better charger, per software. I haven't checked if it's charging at 5v or 9v (I'm not sure if my hardware monitor will accept 9v), but regardless of that, it's well below the amperage of what it should be for either voltage. The other S7 Edge, on its own Samsung OEM charger, took about 2 hours to go from about 50% to 100%, I was told, but I wasn't there to tinker with it or observe. If you're having this issue, please speak up.
This is my first Quick Charge 2.0 phone, coming from an S4 with CM, which I could charge at 1.9amps at 5volts, reliably, as long as I used decent cables and chargers. Using that same phone on the S6 and S7 QC2.0 chargers, it never breaks 1.3amps. The S7 acknowledges "fast charge" mode, but it doesn't actually charge at that rate. When forcing dumb mode at 5v via software or a charge-only cable, the S7 still won't break about 1amp, regardless of using the Samsung charger/cable or a better combo, although it's slightly improved on a better combo.
This really has me curious if it's a kernel issue in addition to poor QC2.0 charger designs (only one QC2.0 charger I've used does its job, correctly, at 5v), but I'm not skilled enough to dig into the kernel, so I'm hoping someone who actually knows the hardware and software side of QC2.0 in the kernel can shed some light on this.
