with the sony xperia x and xa2 series quickcharge devices arrived with sailfish support. the xperia x supports qc2.0, the xa2 varaints support qc3.0 according to sony. but the xa2 uses the qualcomm snapdragon 630 soc, which officially supports qc4.0.

now my questions:

  • does sailfish indicate which charging mode is used? and is the OS even able to see that? - it would be really helpful to have this information, imho. (qc versions or standard usb or usb-pd)

  • would it be possible to use qc4.0 with the xperia xa2? is the limitation to qc3.0 based on hardware or software? - (of course this points to; can we use the possibilities of an open linux to extent the functionality?)

According to Sony, only Quick Charge 3.0 is supported, but a QC 4.0(+) charger should be able to recognize the device as a QC3 device, and only charge accordingly.

I do believe the charging method is hardware controlled. Sailfish do not indicate the charging method.

There's no indicator in Sailfish. But the kernel does see it. You can install a 3rd party app for debugging purposes.

The qualcom chipset is able indeed to see that, and the kernel driver do support it. It just happens that there's no indicator out of the box on Sailfish OS

The native application Chargemon by Kimmoli does report it (on the right pane under "USB connection type" it will display "USB" (dataport on laptop/desktop), "USB_DCP" (legacy USB 5V 1A charger), "USB_HVDCP" (quickcharge 5V/9V/etc. charger), "USB_PD" (USB-C Power Delivery). It will also report the currently detected max current under "USB Max charging current").

But it seems that on XA2 Quickcharge is quite random (It will jump around USB/USB_DCP and USB_HVDCP quit a lot before settling while the USB Max charging current will similarly oscillate around).
