The MTAX2J/A represents a highly specific iteration of the iPhone Xs, a device that marked a significant milestone in Apple's mobile engineering lineage. This particular model identifier, MTAX2J/A, denotes the silver variant of the iPhone Xs equipped with 64 GB of internal flash storage. Understanding this specific part number is essential for collectors, technicians, and secondary market buyers, as it serves as a precise fingerprint for a device designed specifically for the Japanese market. The distinction between this model and its counterparts—such as the 256 GB or 512 GB versions, or those finished in Space Gray and Gold—is critical for ensuring compatibility with regional services and identifying the exact hardware capabilities of the unit in question.
The iPhone Xs, frequently stylised by Apple as both iPhone Xs and the uppercase iPhone XS, introduced a level of refinement in build quality and display technology that set a new benchmark for the premium smartphone segment. By examining the MTAX2J/A, one is looking at a device that integrates a sophisticated 5.8-inch Super Retina OLED display with advanced biometric security and a dual-camera system capable of professional-grade photographic effects. Because this specific model was engineered for Japan, it carries unique hardware identifiers and radio frequency capabilities that differentiate it from the global models sold in the United Kingdom, United States, or Europe.
Hardware Identifiers and Model Nomenclature
Precision in hardware identification is the cornerstone of mobile device management. For the MTAX2J/A, several layers of identification must be understood to distinguish it from other regional or storage-variant models.
The primary identifiers for this specific device are as follows:
- Model Number: A2098 (also associated with EMC 3233)
- Model Identifier: iPhone11,2
- Specific Part Number: MTAX2J/A (Silver, 64 GB)
It is important to note that while the Model Number (A2098) and the EMC number (3233) are unique to this specific device type, they are not explicitly listed on the exterior of the chassis. The Model Number is found on the original packaging and within the device's internal Settings application. The EMC number is only accessible via the Settings application.
The MTAX2J/A is one of several order numbers within the iPhone Xs family. The following table outlines the relationship between colour, storage capacity, and their respective Apple Order Numbers to prevent identification errors.
| Colour | Storage Capacity | Apple Order Number |
|---|---|---|
| Silver | 64 GB | MTAX2J/A |
| Silver | 256 GB | MTE12J/A |
| Silver | 512 GB | MTE42J/A |
| Space Gray | 64 GB | MTAW2J/A |
| Space Gray | 256 GB | MTE02J/A |
| Space Gray | 512 GB | MTE32J/A |
| Gold | 64 GB | MTAY2J/A |
| Gold | 256 GB | MTE22J/A |
| Gold | 512 GB | MTE52J/A |
Display and Visual Engineering
The visual experience of the MTAX2J/A is driven by a 5.8-inch (diagonal) OLED HDR "Super Retina" display. This panel is designed to occupy nearly the entire front face of the device, providing an immersive viewing area. The technological specifications of this display are highly advanced, ensuring high colour accuracy and deep contrast levels.
The display characteristics include:
- Resolution: 2436 x 1125 pixels
- Pixel Density: 458 ppi (pixels per inch)
- Contrast Ratio: 1,000,000:1
- Technology: OLED with HDR support
- Interaction: 3D-Touch equipped
The integration of OLED technology allows for true black levels, which is a direct consequence of the pixels being able to turn off completely, contributing to the massive contrast ratio. This level of visual fidelity is essential for high-definition video playback and professional photo editing on a mobile platform.
Imaging Systems and Computational Photography
The MTAX2J/A features a sophisticated three-camera array, consisting of two rear-facing sensors and one front-facing TrueDepth camera. The rear system is designed for versatility, combining wide-angle and telephoto perspectives to provide a professional photographic experience through a mix of hardware and software intelligence.
The rear camera system is specified as follows:
- Wide-angle Camera: 12.0 Megapixels, f/1.8 aperture
- Telephoto Camera: 12.0 Megapixels, f/2.4 aperture
- Stabilization: Optical Image Stabilization (OIS) supported on both
- Video Capabilities: 4K recording at 24, 30, or 60 fps; 1080p HD at 30 or 60 fps; 720p HD at 30 fps
Advanced software features further enhance these sensors. The combination of hardware and computational logic enables "advanced depth segmentation," Smart HDR, improved bokeh quality, and dynamic retroactively adjustable depth of field. These features allow users to manipulate the photographic focus after the image has been captured, a significant leap in mobile photography capabilities.
The front-facing camera system is integrated into the "notch" at the top of the display:
- Camera Type: TrueDepth camera
- Resolution: 7 Megapixels
- Video: 1080p HD video
- Aperture: f/2.2
- Functionality: Supports Advanced Face ID, Portrait mode, and Portrait lighting
The TrueDepth system is not merely a camera but a sophisticated biometric sensor used for secure identification through Face ID. The ability to shoot 1080p video and 7-megapixel photos from the front ensures that selfie and video calling capabilities are of a high standard.
Internal Processing and Computational Power
At the core of the MTAX2J/A is the Apple A12 Bionic processor. This 64-bit, 7 nm chip is designed to handle intensive tasks through a highly efficient architecture. The processor uses a multi-core approach to balance high-performance demands with power conservation.
The internal architecture consists of:
- Processor: Apple A12 Bionic (7 nm)
- Core Configuration: Six cores (two performance cores and four high-efficiency cores)
- Neural Engine: 8-core Neural Engine for machine learning tasks
- Memory: 4 GB of RAM
- Storage: 64 GB Flash storage (as specified for MTAX2J/A)
The 8-core Neural Engine is specifically dedicated to accelerating machine learning workloads, which directly impacts the performance of the camera's computational photography, Face ID speed, and overall system fluidity. The 4 GB of RAM provides the necessary bandwidth to support multitasking and intensive applications.
Performance benchmarks, derived from independently calculated averages of user-provided results on Geekbench, provide a window into the real-world processing power of the iPhone 11,2 identifier.
| Benchmark Type | Single-Core (SC) Score | Multi-Core (MC) Score |
|---|---|---|
| Geekbench 4 | 4795 | 11149 |
| Geekbench 5 | 1106 | 2701 |
| Geekbench 6 | 1285 | 2654 |
