Why This Matters

The REDMAGIC 11S Pro's innovative liquid cooling system demonstrates significant potential for enhancing gaming performance on smartphones, especially under demanding conditions like heatwaves. This advancement could influence future gaming phone designs, offering consumers more powerful and thermally efficient devices. Its impressive benchmark results highlight the importance of cooling technology in maintaining high performance during intensive gaming sessions.

Key Takeaways

If you want the gaming focus of Android handhelds without giving up a full smartphone experience, then the niche market for gaming phones might be a good fit for you. The latest entry into the field is the REDMAGIC 11S Pro, which touts a new AquaCore Cooling System with a 24,000-RPM Turbo Fan.

The brand claims it’s the first to bring flowing fluorinated liquid cooling to a mass-produced smartphone. Watching the little bubbles flow around the handset’s back is undoubtedly eye-catching, but is it just a gimmick, or does it offer real benefits for demanding gamers?

That’s what I’m here to find out today, with the added twist of an unseasonal UK heat wave to contend with. If a gaming phone can prove its worth in 33°C (91°F) heat, it can prove it anywhere.

Before the heatwave hit, I ran our regular benchmark suite, and the results are equal parts encouraging and worrying for Regmagic’s latest gaming handset.

The good news starts with Geekbench 6, where the phone edges out its competitors, even outscoring the Galaxy S26 Ultra’s overclocked Snapdragon 8 Elite Gen 5 for Galaxy by 3% in both single- and multi-core tests. This makes it the fastest Snapdragon-equipped phone we’ve tested to date.

The Snapdragon chip also opens a sizeable lead over rival silicon. It bests the Dimensity 9500 inside the OPPO Find X9 Pro by 17% in single-core and 21% in multi-core. The Pixel 10 Pro XL’s Tensor G5 processor and its older CPU cores fall even further behind; the 11S Pro has a whopping 65% single-core advantage and nearly doubles its multi-core performance.

But gaming is what you want a REDMAGIC handset for, so I turned to 3DMark’s suite of stress tests to gauge how the handset performs under sustained graphically intensive workloads.
