Xiaomi Black Shark GS3 Ultra Ultimate Specs Features Pros & Cons Revealed

Xiaomi Black Shark GS3 Ultra Overview

The Xiaomi Black Shark GS3 Ultra is a unique and unconventional device released in December 2025. Unlike traditional smartphones, this device seems to emphasize a minimalist design combined with advanced sensors and a robust build, while lacking cellular connectivity or a camera. It is essentially a high-tech feature phone equipped with a compact AMOLED display and essential sensors for health and navigation purposes. This article presents a comprehensive and detailed review of the Xiaomi Black Shark GS3 Ultra, covering everything from design, screen, connectivity, and sensors, to software and battery.

Design and Build Quality

The Xiaomi Black Shark GS3 Ultra features a premium construction consisting of a glass front made with Gorilla Glass for enhanced durability and scratch resistance. The frame is crafted from aluminum, providing a solid and lightweight feel. The device does not support SIM cards and therefore lacks cellular connectivity. Details such as exact dimensions and weight are not specified, but the choice of materials indicates Xiaomi's focus on robustness and elegance. Available in two color options, Black and Silver, it caters to users who appreciate subtle and sleek aesthetics.

Display Features

The device sports a small 1.43-inch AMOLED screen, which is unusual for modern smartphones but is consistent with the feature-phone-like design. Despite the small size, the display offers an impressive peak brightness of 1000 nits, ensuring clear visibility even under bright sunlight. The resolution stands at 466 x 466 pixels, resulting in a pixel density of approximately 326 ppi, which guarantees sharp and vivid visuals for the size of the display. Protection is provided by Corning Gorilla Glass, increasing resistance to impacts and scratches.

Network and Connectivity

One of the most striking aspects of the Xiaomi Black Shark GS3 Ultra is its complete lack of cellular connectivity:

• No 2G, 3G, 4G, or 5G bands supported
• Absence of GPRS and EDGE data technologies
• No SIM card slot or cellular support

However, despite the absence of cellular features, the device includes several other connectivity options:

• Bluetooth support for wireless accessories
• GPS positioning with support for L1+L5 bands, GLONASS, GALILEO, BDS, and QZSS satellite systems, offering highly accurate and reliable navigation capabilities

Unfortunately, WLAN (Wi-Fi), USB ports, and radio receiver functionality are not supported, making this device very focused on standalone or connected Bluetooth experiences.

Camera

There are no cameras included on the Xiaomi Black Shark GS3 Ultra. This is a significant deviation from typical smartphones and even most feature phones on the market today. This indicates the device’s primary usage might be oriented towards fitness, health monitoring, and notifications rather than photography or video capture.

Memory and Storage

The GS3 Ultra does not support expandable storage through microSD cards. No information about internal storage or RAM capacity is provided, suggesting minimal data storage capabilities typical of a feature phone. Additionally, the device does not have phonebook capabilities, but it does support storing call records.

Operating System and Software

Contrary to modern smartphones running Android or iOS, the Xiaomi Black Shark GS3 Ultra operates on a feature phone system. This streamlined OS focuses on essential functions such as SMS with threaded view, email, and instant messaging. It does not support games or Java applications, further emphasizing its functional and utilitarian approach.

Sound and Audio

The device includes a loudspeaker for audio output, but it does not feature a 3.5mm headphone jack. This aligns with its design philosophy of basic communication and notification functionalities with limited multimedia capabilities.

Sensors and Health Monitoring

Despite the minimalistic approach in many areas, the Xiaomi Black Shark GS3 Ultra excels in sensor technology. It comes equipped with a variety of sensors including:

• Accelerometer
• Gyroscope
• Compass
• Barometer
• Heart rate sensor
• SpO2 (blood oxygen) sensor

These sensors collectively allow the device to offer fitness and health tracking capabilities typically found in smartwatches or fitness bands. The inclusion of such comprehensive sensor arrays makes the device ideal for fitness enthusiasts or users who want lightweight monitoring without the distractions of a smartphone.

Battery and Power

Specific details regarding the battery type and capacity are not disclosed, but considering the device’s compact size and limited feature set, it can be inferred that power consumption is low and battery life is likely to be long compared to conventional smartphones. The absence of cellular radios and a small display size significantly reduce energy requirements, prioritizing longevity.

Summary and Use Cases

The Xiaomi Black Shark GS3 Ultra positions itself in a unique category separate from traditional smartphones or even typical feature phones. With no cellular connectivity, no camera, and no Wi-Fi, the device is best viewed as a highly specialized gadget. Its strength lies in offering:

• Robust health and fitness tracking with multiple precise sensors
• High-quality small AMOLED display protected by Gorilla Glass
• Accurate GPS navigation with multi-constellation satellite support

It can serve as a companion device for users who want to minimize distractions or use minimal communication features via Bluetooth paired devices. Moreover, the absence of games and multimedia functionalities reinforces its role as a focused health and utility device. Potential users who want a durable, stylish, and sensor-rich wearable-like device might find the Xiaomi Black Shark GS3 Ultra a fitting choice.
