The JerryRigEverything Durability Test: An Industry Standard
The JerryRigEverything durability test has become a benchmark in the smartphone industry, offering a standardized method to evaluate a device’s ability to withstand everyday hazards. For the Redmi Note 15 Pro+, this test was conducted shortly after its launch, serving as a critical review of Xiaomi’s engineering choices. The test encompasses five key areas: scratch resistance, burn resistance, bend resistance, and a detailed teardown. We will examine each of these components in detail, providing a thorough understanding of what the Redmi Note 15 Pro+ is truly capable of enduring.
Scratch Test: The Mohs Hardness Scale and Screen Protection
The first and perhaps most visually striking test is the scratch test. This assessment utilizes picks of varying hardness, calibrated to the Mohs mineral hardness scale, to determine at what level the smartphone’s screen glass begins to show damage. Most modern high-end smartphones utilize Gorilla Glass or a similar proprietary glass solution, typically achieving a hardness rating between 6 and 7 on the Mohs scale.
Screen Glass Performance
For the Redmi Note 15 Pro+, the display glass began to exhibit scratches at level 6 on the Mohs hardness scale. This is a standard and expected result for aluminosilicate glass used in contemporary smartphones. At level 6, fine scratches become visible under direct light, typically caused by contact with common materials like sand (silica), which has a hardness of 7. Deeper grooves appeared at level 7, indicating the upper limit of the glass’s hardness. This performance is consistent with competitors in the mid-to-high-range segment and offers adequate protection against keys, coins, and other common abrasive objects found in a pocket or bag.
Frame and Back Material Analysis
The durability test also extended to the device’s chassis and rear panel. The Redmi Note 15 Pro+ features a plastic frame, a common choice in this category to reduce weight and cost while maintaining structural flexibility. During the scratch test with a sharp metal object, the frame showed shallow marks but resisted significant damage, a testament to a quality finish or coating.
The back panel, which appears to be a glossy, premium material, was revealed to be made of plastic during the disassembly phase. When subjected to a Mohs pick test, the back panel scratched at a relatively low level, confirming its plastic composition. While plastic is less scratch-resistant than glass, it offers superior impact resistance, as it can flex and absorb shock without shattering. This design choice prioritizes durability over the aesthetic prestige of a glass back, a practical trade-off for a device designed for active use.
Fingerprint Scanner Resilience
A critical component of modern smartphone security is the under-display fingerprint scanner. The test specifically checked if the scanner would remain functional if the glass directly above it were scratched. The Redmi Note 15 Pro+ employs an optical fingerprint sensor, which uses light to capture a 2D image of the fingerprint.
The results were conclusive: even after significant scratching directly over the sensor area, the fingerprint scanner remained fully operational. This demonstrates that the sensor’s functionality is not dependent on the pristine condition of the glass surface. Optical sensors are designed to see through minor imperfections, making them highly reliable even after wear and tear. This resilience is a crucial factor for long-term usability, ensuring that security features remain intact despite superficial damage to the screen.
Burn Test: Thermal Resistance of the Display
The burn test involves applying a direct flame from a lighter to the smartphone’s screen for an extended period, typically up to 60 seconds. This test evaluates the heat dissipation capabilities of the display assembly and the thermal stability of its components, such as the liquid crystals and polarizing layers.
Display Recovery and Integrity
When the flame was applied to the Redmi Note 15 Pro+’s display, the area under direct heat turned black almost instantly due to the thermal sensitivity of the liquid crystals. However, once the heat source was removed, the display remarkably recovered and returned to its normal state within a few seconds. This rapid recovery indicates high-quality display manufacturing with effective thermal management.
The absence of permanent damage, such as pixel burning or delamination of the screen layers, is a significant positive finding. It suggests that the display assembly can withstand short bursts of extreme heat—common in accidental exposure to heat sources—without compromising visual integrity. This level of resilience is vital for users in varied climates or those who frequently use their devices near heat sources.
Bend Test: Structural Integrity and Chassis Rigidity
The final physical test is the bend test, where the device is subjected to manual pressure to check for structural weaknesses. This test simulates scenarios like sitting on the phone or placing heavy objects on it, assessing the rigidity of the frame and the adhesion of the display and back panel.
Frame Flexibility and Durability
The Redmi Note 15 Pro+ demonstrated impressive structural integrity during the bend test. When pressure was applied from both the front and back, the device exhibited minimal flex. The plastic frame, combined with the internal reinforcement, prevented any audible creaking or structural deformation. Unlike devices with metal frames that might bend permanently, the plastic construction allowed for a degree of elastic deformation, returning to its original shape without damage.
The screen and back panel also remained intact, with no cracks or separation from the frame. This indicates robust adhesive application and a well-engineered internal chassis. For users, this means the device can handle the stresses of daily life, from being stuffed into tight pockets to enduring accidental drops, without compromising its structural soundness. The Redmi Note 15 Pro+ passed the bend test with flying colors, affirming its position as a durable and reliable smartphone.
