Pixel 4 XL Becomes the First Google Phone to Support USB Power Delivery 3.0 Fast Charging

The Google Pixel 4 XL now supports USB Power Delivery 3.0 (PD3) fast charging technology on par with other latest phones like the Samsung Note 10+  and Galaxy S10 5G. In fact the Pixel 4 XL was released as Google's first PD3 capable phone over USB Type-C. Rather than getting a higher output charger, the Pixel 4 XL still ships with the legacy Google 18W power adapter just like previous models.

While the Pixel 4 XL retains a lot of specs from the Google Pixel 3 XL, the phone offers a few hardware upgrades such as a new telephoto rear camera, a TOF 3D front camera along with a newer and faster Qualcomm SDM855 Snapdragon chipset and Adreno 640 GPU. Other new features include a Face ID sensor and a 90Hz display refresh rate. The phone also comes with a upgraded non-removable Li-Po 3700 mAh battery, 6GB RAM memory and runs on Android 10. 

The Pixel 4 XL continues to support Qi wireless charging and eSIM technology just like the Pixel 3 XL.

The packaging of the Pixel 4 XL shows off the new telephoto rear camera which Google heavily markets for its latest phone. This additional 16MP, 1.0µm, f/2.4 camera offers better zoom quality and portrait mode versus the single rear camera on the Pixel 3 XL. The new camera design also makes the Pixel 4 XL looks a lot different than the previous model.

The Pixel 4 XL ships with a 18W USB Power Delivery based USB Type-C power adapter among its accessories. The 18W AC power adapter looks like the typical Google charger used by the Pixel phone family supporting 15 watts (5 volts @ 3 amps) and 18 watts (9 volts @ 2 amps) power profiles.

For some reason the Pixel 4 XL is missing the wired USB Type-C earphones and USB Type-C to 3.5mm audio adapter that shipped with the Pixel 3 XL.

Using the USB Power Delivery Compliance C2 Tester from Granite River Labs to run just a subset of the full USB Power Delivery compliance test suite, some compliance failures were observed for the Pixel 4 XL.
