GSMArena tested the Google Pixel 11 battery and charging, comparing it against the Pixel 10, Galaxy S26, and iPhone 17. The Pixel 11 scored an Active Use Score of 15:40h, a major improvement over the Pixel 10's 12:08h, and matched its key rivals. Gaming remained a weak point due to the IMG CXTP-48-1536 GPU from Imagination, but power efficiency improved significantly, nearly closing the gap with the Galaxy S26 and iPhone 17.

The Pixel 11 also showed a significant improvement in video playback testing. For charging, wired speed remains capped at 30W, while wireless charging increased to 25W. Google introduced an Extreme Charging mode, which requires an adapter delivering 11V and 3A for fastest speeds.

While the Pixel 11 doesn't lead in any single test, it avoids the weaknesses seen in the Pixel 10 generation.
