With Google's Android 9.0 Pie OS update fresh out of the oven, some Pixel owners have already run into a bug that Google apparently won't fix.

Several Pixel XL owners have reported that their phones have stopped fast-charging ever since they upgraded to Android Pie. The bug was added to Google's Issue Tracker, but labeled "Won't Fix (infeasible)" after Google looked into the problem.
