Google failed a little last year with wireless charging on the Pixel 3. Only customers who bought their own Pixel Stand accessory and a very small selection of external chargers could operate the Pixel 3 at the fastest possible wireless charging speeds. All others who used their existing mats and charging standards were limited to a much slower 5-watt charge. But Google has corrected this error with the Pixel 4.
According to Mishaal Rahman of XDADevelopers, the Pixel 4 and 4 XL support 11-watt wireless charging. This is confirmed on a page for the device at the Wireless Power Consortium, and has been further verified by direct testing.
Any Qi-compatible charger that can run 11 W or more must be able to charge the Pixel 4 with that maximum power level – no Pixel Stand or expensive, customized certification required.
As Rahman points out, in the run-up to launch, Google has never mentioned the ability of the Pixel 4 to charge faster on a larger number of charging pads. Maybe the company has just decided to quietly give up its bizarre strict approach and bring the new Pixel closer to the other Android flagships that enable fast wireless charging. Some people may find the Pixel 4 too expensive, but at least you can save on a charger if you are sold on the latest phone from Google.
