After months of testing through its beta program, Google finally made Android 9.0 Pie available in an official capacity to Pixel devices last week. While it brought a slightly redesigned UI and other important features, it also managed to break fast charging on first generation Pixel handsets.
The problem only seems to occur with Pixel devices that aren’t using the stock charger that came with the smartphone. While it doesn’t affect all third-party chargers, many folks have reported the issue when using a third-party charging device.
Google is aware of the issue and spoke with The Verge about the situation stating:
“We’re aware of an issue where non-Power Delivery (PD) USB-C chargers no longer rapidly charge the 2016 Pixel and Pixel XL after the upgrade to Android 9 Pie. The 18W rapid charger included in-box is a PD charger and does not exhibit this behavior. We are verifying a fix for non-PD USB-C chargers and will roll it out in the coming weeks.”
It did not state when exactly the fix would be available, but as you can see in the statement above, it should arrive in the coming weeks. So for now, you can use the charger that came inside the box for fast charging or use your third-party charger with knowledge that it’ll be charging your phone at a slower pace.
