Google has long been committed to making phone charging more than convenient. It was among the first to offer wireless charging, back before everyone got bored with it the first time around. More recently, it has focused on fast wired charging. The 2016 Pixel Xl shipped with speed 18W fast charging, merely something appears to have gone wrong in the recent Android Pie update. This phone's maximum charging speed is now painfully deadening.

Like all Google devices since the 2015 Nexus phones, the Pixel Forty has support for USB Ability Commitment (USB-PD) standard. USB-PD has increasingly shown up in phones from LG, Samsung, and others, fifty-fifty if there'due south another fast charging standard in the included plug. This standard supports a plethora of charging modes going all the way upward to 100 watts. Laptops like the Pixelbook and MacBook Pro employ USB-PD over Type-C ports to recharge, which often operate effectually 40-60W.

The Pixel XL supported 15W and 18W fast charging at launch, which is around what most other Android phones tin practice. The current Pixels likewise support these charging speeds. However, users of the Pixel 40 encountered a issues starting in the afterward Android P developer preview builds that completely disabled fast charging. Someone started a bug tracker thread for the outcome, and Google seemed to take find. However, the final build rolled out, and a large number of non-beta users accept the same effect.

I've been able to ostend with my dev preview test unit of measurement that the final version still has the fast charging bug. With a Google charger, the phone doesn't get either 15W (5V 3A) or 18W (9V 2A). It'south pulling about 9V and 0.55A, which is 5W. That's the fallback low-power charging speed that predates even the original Qualcomm Quick Charge applied science. It's and so incredibly dull by today's standards.

In an alarming motion, Google even marked that original issues thread as "Won't Set (Infeasible)." Google reserves that designation for bug that cannot exist fixed on Google's terminate considering they're caused by a third-party manufacturer or application. This bug is all Google, though. Users have started another thread, which Google has non officially recognized yet.

And so far, this issue seems limited to the 2016 Pixel Twoscore. The smaller 2016 Pixel has a slightly different fast charging setup that could only do 15W, and then maybe that'southward why it has been spared from the bug. If you're a Pixel 40 user and fast charging is vital, you might want to hold off on that Pie update if it's not already besides late.
