Google Says Pixel 6 Charges Exactly As Fast As It Should

Google sells a 30W charging brick for its latest smartphones, but the company has now clarified that the peak charging wattage for the Pixel 6 is 21W, and 23W for the Pixel 6 Pro. The situation is particularly interesting considering the wired charging rates match the wireless charging figures. If used with the new Google Pixel Stand (2nd gen) wireless charger, the Pixel 6 and 6 Pro can be juiced up at 21W and 23W respectively. 

Earlier this month, a test revealed that the Pixel 6 peaks at 22W while connected to Google’s 30W USB-C charger that's sold separately by the company. As for the Pixel 6 Pro, the phone struggled to go past 22W in the test, and the wattage only went down as the battery levels went up. Multiple people from within the tech journalism community predicted that it has something to do with battery longevity and degradation issues.

Google has now confirmed those speculations in detail. A community manager on the Google support forum confirmed that the vanilla Pixel 6 can draw a peak power of 21W from its 30W charger, and the Pixel 6 Pro can go up to 23W. As the battery levels inch closer to the 100-percent mark, the charging speed is reduced gradually. Google argues that the aforementioned charging behavior is best for battery health. “Google has designed the high energy density cells in Pixel 6 and Pixel 6 Pro to strike a balance between battery life, longevity and fast charging,” the post adds. Another important point to note here is that charging will vary depending on various factors, such as internal design of the cells, overall temperature, whether the phone is being used or sitting idle, and the charging method. 

It is actually quite normal for phones to automatically slow down the pace of charging if the battery heats up. Plus, the speed of charging also follows a multi-stage path. A commonplace observation is that the charging rate slows down around the 70 to 80-percent battery level. In case of the Pixel 6 series, it takes around 30 minutes to reach 50-percent battery, but going from 50-percent to 80-percent takes another 30 minutes. The charging speed is reduced further as the battery comes closer to 100-percent.

The problem with extremely fast charging for a sustained duration is that it can lead to chemical degradation, which means the charge retention capacity is slowly reduced over time. The Pixel 6 phones also come with Adaptive Charging that further slows down the charging pace and only tops off fully by the time a user's morning alarm goes off. It is a thoughtful addition, as as a healthy percentage of smartphone users charge their phones overnight. Without such a safety check, fast charging will lead to faster chemical degradation and reduce the lifespan of the battery. While Google's Adaptive Battery is enabled by default, it can be turned off for those that want to see a small uptick in the charging rate.
