This Water Cooled Phone is the Fastest We’ve Tested

Product Reviewed

Red Magic 11 Pro (sponsored) — positioned as the world’s first mass-produced liquid-cooled phone, aimed at gaming performance.

Key Features Mentioned

Cooling System

• Liquid cooling system (“tiny water cooling” inside the phone), with a visible pump inside a cooling loop.
• Heat control also relies on additional cooling components:
  • Largest vapor chamber Red Magic claims for the phone industry
  • 24,000 RPM fan to assist the vapor chamber

Gaming-Focused Hardware

• Snapdragon 8 Elite Gen 5 (8-core) + Adreno 840 GPU
• Claims of improved performance vs previous Red Magic generation:
  • Better raster and ray-traced performance
• Memory/storage:
  • Up to 24GB LPDDR5T (Turbo) RAM (faster than LPDDR5X; before LPDDR6)
  • Up to 1TB UFS 4.1 storage

Display

• 144 Hz AMOLED
• Brightness claims:
  • “1,800 nits peak” (rated)
  • Reviewer measurement:
    • Regularly over 2,000 nits
    • Peak just over 2,400 nits
• Over 95% screen-to-body ratio

Cameras

• Rear: dual 50MP + 2MP (distance measuring) + quad LED flash
• Front:
  • No cutout/dynamic island
  • Uses lower-density pixels around the selfie camera area
• Notable design: no rear camera bump
  • Helps gaming comfort and keeps the phone flat

Battery & Charging

• Battery: ~7,500 mAh (27.77 Wh) (described as unusually large)
• Usage claims:
  • Up to 34 hours daily usage
  • Reviewer measurement:
    • Just over 22 hours continuous video playback
• Charging:
  • Up to 80W wired and two-way wireless
  • Reviewer measurement:
    • Full 80W only briefly, then settled around ~60W
  • Claim: 0–100% in 59 minutes

Audio & Ports / Physical Design

• Headphone jack
  • Highlighted as “old school cool” and practical
• Stereo speakers
• Physical layout includes:
  • triggers, lock button, volume rocker, game mode switch, intake, SIM tray, USB-C, microphones
• IPX8 rated body

AI Assistant Integration

• Mentions “Mora” (AI in-game helper; anime/waifu-style joke)
  • Can chat and provide in-game tips
• Reviewer implies Gemini AI integration and jokes about its intelligence

Performance / Benchmark Claims (No Numeric Scores Provided)

The reviewer says the Red Magic 11 Pro delivered:

• Highest 3DMark and Geekbench mobile benchmark scores they’ve ever tested
• Higher benchmark results than other phones tested with the same processor

Caveat raised: the fan curve/fan tuning may still need refinement to keep thermals under control during heavier sustained loads.

Cooling Effectiveness & Thermals (Qualitative)

• The reviewer suggests the liquid cooling alone likely doesn’t do “a lot” of cooling—it mainly moves heat.
• Primary cooling is described as coming from:
  • vapor chamber + high-RPM fan
• Stress behavior:
  • Surface temps rise in stress scenarios, especially under heavier repeated tests
  • In typical gaming, extreme heat is less likely because many mobile games are FPS capped
• Additional note:
  • Thermal interface material exists between the SoC copper heat spreader and the screen area, implying significant dissipation through the screen

User Experience Observations

Gaming Convenience

• No camera bump helps the phone sit flat during play/use

Thermals vs Everyday Gaming

• Real gaming likely stays cooler due to FPS caps
• Sustained/benchmark-level loads may require higher fan operation

Fan Noise

• The 24,000 RPM fan is audible at maximum performance (especially without headphones)

Headphone Jack Practicality

• Called convenient and low-friction, supported by a modular headphone jack approach

Charging Experience

• Fast charging is “real” (brief 80W peak)
• Charging stabilizes around ~60W over longer sessions

Pros (Stated or Strongly Implied)

• Top-tier benchmark performance (best scores the reviewer has seen)
• New cooling approach: liquid cooling + vapor chamber + very high-speed fan
• Very bright display (measured above rated specs)
• Excellent usability:
  • 144Hz
  • High screen-to-body ratio
  • No disruptive selfie cutout
• Huge battery with strong real-world playback endurance
• No camera bump for better stability while gaming
• Headphone jack and stereo speakers
• IPX8 rating

Cons / Limitations Mentioned

• Liquid cooling may be secondary to vapor chamber/fan, mainly moving heat
• Fan noise at maximum load
• Fan curve tuning may need refinement for sustained maximum-power scenarios
• Front camera isn’t “sharpest in the world” (but avoids screen interruptions)

Comparisons Made

• Battery capacity comparison

  • Reviewer claims the battery is ~50% more than Pixel 10
  • Also claims about double iPhone 17 (with apples-to-oranges caveat)

• Thermal/stress behavior comparison

  • Contrasts benchmark-style power stress with FPS-capped mobile games, noting heat effects differ

Tear-down / Build Details Called Out

• Liquid cooling loop appears partially obscured/covered in some views/backs
• A sticker may have been used over the liquid coverage area in a protected/accessible build
• Liquid system includes:
  • a very thin “liquid” element/pump area (described as thinner than a playing card)
• Modularity highlight:
  • Headphone jack on a ribbon daughterboard, suggesting easier replacement vs a more integrated design

Overall Verdict (Concise)

Recommended for gamers who want maximum performance and sustained speed in demanding workloads—especially since the phone posts record-best benchmark scores and pairs an unusually robust cooling system with a huge battery and a very bright 144Hz AMOLED.

Main tradeoffs: fan noise under full load and the suggestion that cooling effectiveness from the liquid loop may be secondary to the vapor chamber/fan, with potential fine-tuning still needed for sustained extreme workloads.
