Back in August, when Android Pie was in Beta mode, some Google Pixel and Google Pixel XL smartphones on the program lost their fast charging. The issue was expected to be fixed by the time the stable version rolled around but it was still there.
Now Google says the problem is fixed with the October security update.

The latest monthly patch fixes the problem with the communication between third-party USB-PD adapters and the phone, although the issue appeared with original chargers as well. Updates for the Pixel 2 arrived as well – they are fixing Android Auto stability and improved performance for certain protected media formats.
The update is already rolling out to all Pixel phones so the end of your slow charging torture is near.
