The REDMAGIC 11 Pro, the world’s first smartphone with a liquid-cooling system, has undergone a brutal durability test by a well-known YouTuber famous for putting gadgets through extreme physical trials. The video, titled “The Coolest Smartphone I’ve Ever Held — (Not Clickbait)”, quickly gained thousands of views and confirmed that Nubia’s gaming flagship can handle not only intense gameplay but also serious mechanical stress. Here’s what the test revealed and why this device stands out from its competitors.

Liquid Cooling: The Heart of the Beast

The REDMAGIC 11 Pro features a unique liquid-based cooling system made up of three main components: an active liquid-cooling loop, a built-in fan, and a massive vapor chamber. Together, they allow the phone to sustain peak performance without throttling — temperatures remain below 40°C even during heavy gaming sessions in titles like Genshin Impact at maximum settings.

During the teardown, the reviewer was impressed to find that the coolant circulates continuously, keeping both the Snapdragon 8 Elite chip and GPU cool. The highlight came when the phone was set on fire — remarkably, the cooling system kept functioning, channeling heat away from the components. The reviewer commented that this was “not just a fan, but an engineering masterpiece.” While the design makes it ideal for gamers, it also means repairs are complex and must be handled by professionals.

Build Strength: Unbendable Under Pressure

The YouTuber’s attempt to bend the device by hand failed completely. The matte aluminum frame withstood the usual “bend test” stresses popularized by channels like JerryRigEverything. The display only scratched at level 6 on the Mohs scale, comparable to Gorilla Glass Victus, while the rear panel and frame showed minimal damage from keys and sand.

The REDMAGIC 11 Pro is also rated IP68/IP69, surviving both full submersion and high-pressure water jets. It meets the MIL-STD-810H military standard, enduring drops from 1.5 meters, vibrations, and extreme temperatures. The reviewer concluded that the REDMAGIC 11 Pro is one of the toughest flagships of 2025.

Under-Display Camera and Other Highlights

The 16 MP front camera is hidden beneath the display — there’s no notch or hole-punch, leaving a clean 6.8-inch OLED screen with 144 Hz refresh rate and 2000 nits brightness. Selfie quality is solid but slightly weaker in low light compared to Samsung’s perforated cameras. The rear setup includes a 50 MP main lens with OIS, a 50 MP ultrawide, and a 2 MP macro — perfectly fine for social media and gaming shots, though not for professional use.

The 6500 mAh battery with 80 W fast charging supports up to 10 hours of gaming. The device runs Android 15 with REDMAGIC OS, features stereo speakers with Dolby Atmos, and includes an under-display fingerprint sensor.

In Brief…

The REDMAGIC 11 Pro passed all durability tests: its liquid cooling system survived fire, the body resisted bending, the display scratched only at level 6, and it maintained IP69 protection. With a hidden camera, long-lasting 6500 mAh battery, and extreme performance, it lives up to its gaming reputation — though repairs are expensive.

According to the YouTuber, it’s “the coolest smartphone of 2025” — literally and figuratively — built for gamers, but not necessarily for everyone.
