This one is genuinely embarrassing for Google. A new battery endurance test has revealed that the Samsung Galaxy S26 — which carries a battery roughly 1,000mAh smaller than the Pixel 10 Pro XL — outlasts Google’s flagship by over 3 hours in video playback and nearly 2x longer in gaming. The culprit is no mystery: Google’s Tensor G5 chip.

Galaxy S26 vs Pixel 10 Pro XL: Battery Test Results
| Test | Samsung Galaxy S26 | Google Pixel 10 Pro XL |
|---|---|---|
| Battery Capacity | ~4,300mAh | ~5,200mAh |
| Active Use (Average) | 15 hrs 20 mins | 12 hrs 29 mins |
| Advantage | +2 hrs 51 mins | — |
| Video Playback Gap | S26 wins by 3+ hours | — |
| Gaming Gap | S26 lasts nearly 2x longer | — |
| Chipset | Snapdragon 8 Elite Gen 5 | Google Tensor G5 |
Why the Tensor G5 Is the Problem
he Tensor G5 chip excels at AI-related tasks but falls short of the competition in most other areas — and the battery results lay that bare. The chip uses ARM’s now-nearly-three-year-old CPU cores to save on costs, which shows up in degraded performance versus peers, and pairs them with an Imagination IMG DXT-48-1536 GPU that lacks ray-tracing support.

The result is a chip that burns through battery doing the same tasks a Snapdragon handles far more efficiently. This test goes a long way to practically demonstrate that mindlessly cramming extra milliamp hours in your battery counts very little if your chip is as unoptimised as the Tensor G5.
Meanwhile, the Snapdragon 8 Elite Gen 5 in the Galaxy S26 destroys the Tensor G5 in graphics testing — with both score and frame rate more than double what the Pixel manages in 3DMark Wild Life Extreme. Check out our full Galaxy S26 coverage on Technosports for more.
