At the time of launch, Google advertised 30W charging speeds for the Pixel 6 and Pixel 6 Pro.
Google has confirmed that the Pixel 6 can receive a peak power of 21W from a wired charger. The Pixel 6 Pro, on the other hand, is said to be capable of 23W peak power from a wired charger. This is significantly less than the 30W wired fast charging advertised at the time of launch. Google has now released information on how charging works on the new Pixel phones. It claims that the actual power delivered over the course of a single charge cycle varies. This variable charging rate was introduced to extend the battery’s life.
Google explained how charging works on the Pixel 6 and Pixel 6 Pro in its Pixel support forum. “We’ve optimized Pixel’s lithium-ion battery for high charge rates when the battery level is low,” says Camille V., Community Manager. The Pixel 6 can charge to 50% in about 30 minutes (with Google’s 30W USB-C Power Charger) and quickly to 80% in about an hour, depending on device usage and temperature.”
According to the post, the peak power drawn by the Pixel 6 and Pixel 6 Pro from the wired charger is 21W and 23W, respectively. “As the battery approaches full capacity, charging power is gradually reduced to improve battery longevity,” she adds.
The latest development follows reports that the Google Pixel 6 Pro’s charging is much slower than expected. In a recent test, the Pixel 6 Pro took approximately 111 minutes to fully charge its 5,000mAh battery, whereas the Samsung Galaxy S21 Ultra charges in 62 minutes — 49 minutes faster.
Under certain conditions, Google warns that the Pixel phones may also pause charging above 80%. Enabling Adaptive Charging to optimize charge rate for gradual overnight charging is also recommended by the tech giant.
Furthermore, Google recommends that users use the company’s 30W USB-C Power Adapter and the newly launched Pixel Stand to draw the maximum power required to charge the Pixel 6 and Pixel 6 Pro quickly.
