Smartphone cooling systems rarely become the centerpiece of a device's design, but the RedMagic 12 Pro makes its elaborate thermal engineering impossible to ignore. JerryRigEverything examines this gaming-focused flagship through his familiar combination of durability testing and internal disassembly, revealing a dual-loop liquid cooling system, a high-speed internal fan, and an unusually ambitious collection of hardware features. His enthusiasm is immediately apparent, particularly when discussing the phone's transparent design elements and visible coolant circulation. Although the presentation occasionally approaches promotional territory, the opportunity to see how these technologies are physically integrated makes the examination genuinely fascinating.
The phone's exterior provides plenty of interesting engineering decisions before the durability testing begins. Its 6.85-inch display reportedly offers a 185Hz refresh rate, 5,000-nit peak brightness, extremely narrow bezels, and an impressive 96.3% screen-to-body ratio. Jerry also examines the ninth-generation 16-megapixel under-display selfie camera, using microscopic inspection to demonstrate how effectively RedMagic conceals it beneath the display pixels. His comparison with Apple's approach illustrates a meaningful design compromise between camera visibility and uninterrupted screen appearance. However, the discussion concentrates on the visual advantages of concealing the camera rather than evaluating its actual photographic performance.
The durability testing provides a reassuring assessment of the phone's physical construction. Gorilla Glass 7i produces scratches at level six with deeper grooves at level seven, while the aluminum frame and completely flat rear glass contribute to a substantial overall structure. The display survives the brief lighter test without permanent visible damage, and the phone withstands bending pressure without noticeable flex or structural failure. Particularly interesting is the combination of water resistance and active air cooling, which requires carefully separated internal compartments and protective seals. Jerry explains the potential for dust accumulation inside the air channel, although the demonstration does not establish how effectively the ventilation system resists contamination during prolonged use.
The teardown is unquestionably the presentation's highlight, exposing the AquaCore Cooling System 3.0 and its elaborate arrangement of liquid channels, airflow ducts, and thermal components. Removing the rear glass and decorative shielding reveals a considerably more complex cooling system than the previous generation's arrangement. Jerry traces the coolant's movement through differently sized tubes and identifies the tiny piezoelectric pump responsible for circulation. The claimed 85% improvement in cooling performance and the coolant's reported operating temperature range are impressive specifications, but they remain manufacturer claims rather than independently verified results. Nevertheless, seeing the physical coolant pathways and the metal air duct connected to the phone's thermal components provides valuable insight into the engineering behind the design.
Further disassembly reveals how extensively RedMagic has prioritized heat management. The 25,500 RPM fan, liquid cooling channels, thermal paste, copper components, and large vapor chamber work together within a surprisingly compact internal structure. Jerry explains the relationship between these components and the processor, while also showing the protective rubber gaskets and mesh screens surrounding the ventilation system. The 8,400mAh battery, 80W charging capabilities, and additional cooling activation during fast charging further demonstrate the manufacturer's emphasis on sustained power delivery. Unfortunately, the examination stops short of measuring actual processor temperatures, sustained gaming performance, fan noise under realistic workloads, or battery endurance, leaving the practical effectiveness of the elaborate cooling architecture largely untested.
Several smaller discoveries make the disassembly particularly rewarding. The dual shoulder triggers, programmable gaming button, ultrasonic fingerprint sensor, stereo speakers, and substantial battery capacity collectively reinforce the device's gaming identity. Jerry also examines the camera modules, identifying optical image stabilization on the main camera but not the ultrawide or front-facing units. The absence of a headphone jack and built-in wireless charging magnets represents practical compromises that receive relatively little critical attention. Similarly, the suggestion that the vapor chamber might be gold-plated remains speculation rather than a confirmed finding. These details add personality and technical interest, but the presentation is far more comprehensive as a hardware inspection than as an assessment of everyday usability.
Jerry's conversational delivery helps make a highly technical teardown entertaining without burying viewers in complicated terminology. His humorous comparisons, playful reactions, and visible excitement communicate genuine appreciation for the phone's internal construction. The gradual progression from exterior inspection to increasingly intricate components gives the demonstration a satisfying sense of discovery. However, frequent superlatives, enthusiastic comparisons with competing smartphones, and repeated giveaway promotions sometimes distract from the engineering discussion. The ending also feels somewhat incomplete because the anticipated reassembly outcome is not demonstrated, and the video never establishes whether the device's elaborate thermal system delivers meaningful advantages over competing gaming phones. Despite these shortcomings, the combination of detailed disassembly and accessible explanations makes the presentation an engaging exploration of unusually ambitious smartphone hardware.
Pros
- The detailed teardown reveals an exceptionally intricate dual-loop liquid cooling system and explains how its major components fit together.
- Microscopic inspection provides a convincing visual demonstration of the nearly invisible under-display selfie camera.
- The scratch, heat, and bending tests offer useful evidence of the phone's physical durability.
- The examination of coolant channels, the piezoelectric pump, thermal interfaces, and internal airflow makes complex engineering accessible.
- The discussion of the large battery, active cooling, gaming controls, and display specifications highlights the phone's distinctive hardware priorities.
- The comparison with the previous generation helps illustrate how RedMagic has expanded its cooling architecture.
- Jerry's enthusiastic narration and methodical disassembly maintain interest throughout a technically detailed presentation.
Cons
- The claimed 85% cooling improvement is presented without independent thermal measurements or comparative benchmarks.
- The absence of sustained gaming tests leaves the system's real-world performance advantages largely unverified.
- Camera quality, battery endurance, software experience, and everyday usability receive minimal attention.
- The manufacturer's premium performance claims and comparisons with competing smartphones are sometimes accepted too enthusiastically.
- Giveaway promotions and exaggerated praise occasionally interrupt the technical examination.
- The presentation does not demonstrate successful reassembly or verify whether the phone remains fully functional afterward.
JerryRigEverything delivers an entertaining and technically revealing examination of one of the more elaborate smartphone cooling designs presented in recent years. The detailed disassembly, visible coolant circulation, and substantial durability testing make the RedMagic 12 Pro fascinating from an engineering perspective. Although the enthusiastic presentation would benefit from independent performance benchmarks and a more critical assessment of practical compromises, it succeeds as an engaging hardware exploration rather than a comprehensive smartphone review.
