Once again, Pixel 6 Pro charging speeds can't match the Galaxy S21 Ultra

The rules of our test were as follows: the Galaxy S21 Ultra and Pixel 6 Pro were charged in one go in airplane mode from 0% charge using the official 25W and 30W chargers, respectively. These have to be purchased separately, by the way, as neither phone comes with a charger in the box.

Furthermore, we made sure to disable Adaptive charging on the Pixel 6 Pro and Protect battery on the Galaxy S21 Ultra to make this as fair a test as possible. Protect battery originated on tablets, but the feature began making its way onto Galaxy smartphones back in August.

Galaxy S21 Ultra vs Google Pixel 6 Pro charge speed test results

As you probably expect, the Galaxy S21 Ultra did came out on top in this test. But more interesting is how these phones perform side-by-side. Each device has a 5,000mAh battery, but their power management systems are very different — as evidenced throughout our benchmark.

At the 15 minute mark, the Galaxy S21 Ultra had only a 2% advantage over the Google Pixel 6 Pro, but by the time Samsung's flagship reached full charge, the Pixel 6 Pro was sitting at 87% charge.

The more unexpected result is that while the Galaxy S21 Ultra finished charging in 1 hour and 12 minutes, the Pixel 6 Pro began to struggle in the final stretch and reached 100% charge in 2 hours and 2 minutes. Clearly, not every 5,000mAh battery performs the same.
