Knowledge
Explained concepts and technologies
Ultrasonic fingerprint sensor
A fingerprint-based biometric authentication method that uses ultrasonic technology and is positioned beneath the device display.
WiFi 7 (IEEE 802.11be)
WiFi 7, designated as IEEE 802.11be, is the seventh generation of the WiFi wireless networking standard. It is characterized by triple-band frequency operation and appears as a connectivity specification in consumer and mobile devices alongside other wireless technologies.
HyperOS
HyperOS is the mobile operating system developed by Xiaomi, replacing MIUI and based on Android. Available evidence confirms the existence of the HyperOS 3 version.
Snapdragon 8 Elite
The Snapdragon 8 Elite is a high-end chipset developed by Qualcomm, manufactured using a 3-nanometer process. Designed for next-generation mobile devices, it offers a balance between CPU/GPU performance and energy efficiency, serving as the core of premium smartphones.
Silicon-carbon battery
Lithium-ion battery technology that uses a silicon-carbon composite anode to increase energy density over conventional graphite.
Pulse-width modulation (PWM) dimming
A dimming method identified in a display record with a stated PWM frequency of 3840 Hz; the same record also mentions 120 Hz without explaining how the two figures relate.
HDR
HDR (High Dynamic Range) is an imaging technology that expands the range of tones and colors to improve contrast and visual fidelity in displays and cameras.
Corning Gorilla Glass
Corning Gorilla Glass is a family of protective glass products manufactured by Corning, used as front (display protection) and rear material in consumer electronic devices such as smartphones.
USB Type-C 3.2
USB Type-C 3.2 (also designated USB-C 3.2) is a USB connector standard that combines the reversible Type-C physical interface with the 3.2 data-transfer specification. It is associated in products with DisplayPort 1.2 and OTG capabilities.
5G NR
5G NR is a designation associated with 5G connectivity. In the available evidence, it appears with a specific list of supported n bands for a product; that list states declared scope, not guaranteed service availability.
Wireless Charging
Wireless charging is a mode of electrical energy transfer to a device without a physical cable connection. In documented implementations it operates at 30 W, can coexist with higher-power wired charging (45 W), and may include complementary features such as Bypass Charging.
LTPO AMOLED Display
LTPO AMOLED is a display panel type that combines an active-matrix organic light-emitting diode (AMOLED) matrix with a low-temperature polycrystalline oxide (LTPO) backplane, enabling variable refresh rates on large-format screens such as 6.8-inch panels operating at 165 Hz.
IP68, IP69 and IP69K protection ratings
IP68, IP69 and IP69K are rating designations that, in the available evidence, are jointly attributed to a product. The source does not provide their test conditions, technical scope, or a breakdown of their meaning.
UFS 4.1
UFS 4.1 is a revision of the Universal Flash Storage standard, a flash memory storage type used in consumer electronic devices. Available evidence confirms its presence as a storage type in commercial products, in 256 GB and 512 GB variants.
Light Fusion 950 Image Sensor
The Light Fusion 950 is an image sensor designed to capture a wide dynamic range, facilitating photography in complex lighting conditions.
DisplayPort
DisplayPort is a digital video interface standard used to connect monitors and other display devices to signal sources, such as graphics cards or computers.
Telephoto Lens
Optical camera component designed to capture images at a distance with increased focal reach.
DDR5X Memory
DDR5X memory is a high-speed specification within the LPDDR5X family, designed to provide data transfer rates of up to 9600 MT/s in next-generation mobile devices.
Gyroscope Electronic Image Stabilization (Gyro-EIS)
Gyro-EIS is an electronic video stabilization technique that uses gyroscope data to digitally compensate for camera motion during recording. It appears as a specification in smartphone datasheets and can coexist with optical image stabilization (OIS).
TSMC 3nm Fabrication Process
The TSMC 3nm fabrication process is an advanced lithography technology used to manufacture high-density, energy-efficient semiconductors, notably adopted in next-generation mobile chips.
HDR10
HDR10 is a high dynamic range video standard that defines metadata and encoding for compatible displays, enabling a wider color gamut and contrast.
8K Video Recording
8K video recording is the capture of moving images at 8K resolution. In documented implementations, the maximum recording specification is 8K at 30 fps, with Dolby Vision support as the associated high dynamic range format.
Periscope Telephoto Lens
A periscope telephoto lens is a camera optical system that uses a folded light path via mirrors or prisms to achieve optical zoom within a compact footprint. Recent implementations have been documented with 50 MP sensors and 3× optical zoom.
OIS (Optical Image Stabilization)
Optical Image Stabilization (OIS) is a technology that compensates for camera movement by physically shifting the sensor or optical elements, improving sharpness in low-light conditions or when using zoom.
