Let battery run out. Connect Sailfish X to USB port. Led changes to green. Phone does not charge. Workaround: charge with charger.

Maybe your computer USB port does not give enough current?

Removed the "bug" tag since this is not a bug. The phone is intended to be charged by a 2 A charger and an USB port only provides 500 mA.

Hi.

I would be careful about these 2 Amps mentioned before: the charger provided with my Xperia X only provides a maximum current of 1.5 A. Higher currents may damage the battery!

Regards.

Devices will only draw the current (amp) they need / can use. As long as the device is getting the correct voltage ("electrical pressure") of 5 volts, the available amps can be any amount.

see under power here: en.wikipedia.org/wiki/USB

usb can give 1,5 A if made to. the port itself can handle up to 5 usb

Of course it's not a current generator. 2 A or 1.5 A or whatever is the maximum amount of current guaranteed to be supplied without significant voltage drop.
