Knowledge
Explained concepts and technologies
Power Delivery 3.0
Power Delivery 3.0 (PD 3.0) is a fast charging specification that enables up to 100 W of power transfer over a USB-C cable.
High-frequency PWM Dimming
A pulse-width modulation technique used in displays to reduce perceptible flicker and improve visual comfort.
Hi-Res Audio
Hi-Res Audio is a high-resolution audio standard that exceeds CD specifications, typically defined by 24-bit depth and a sampling rate of up to 192 kHz.
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.
Bluetooth
Short-range wireless communication standard.
ARM Cortex-A725 Core
The ARM Cortex-A725 is a high-performance processor core from ARM's Cortex-A family, documented in heterogeneous multi-core SoC configurations with clock speeds ranging from 2.2 to 3.4 GHz.
Dolby Vision
Dolby Vision is a registered HDR (High Dynamic Range) video and display format that extends the dynamic range of images to deliver cinematic depth. It is used for both on-screen playback and video recording in mobile devices and other consumer products.
HDR10+
HDR10+ is a high dynamic range (HDR) format applicable to both display and video capture, operating at 10-bit colour depth. It appears in mobile device specifications alongside high-refresh-rate AMOLED panels with elevated peak brightness.
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.
Optical Fingerprint Sensor
A biometric component that captures a fingerprint image using optical illumination for user authentication in electronic devices, primarily smartphones.
LPDDR5X
LPDDR5X is a low-power (Low Power DDR5X) RAM type found in consumer electronic devices. Available evidence documents its use in 12 GB and 16 GB configurations.
AMOLED
AMOLED (Active Matrix Organic Light-Emitting Diode) is a display technology in which each pixel emits light independently through organic compounds driven by an active matrix of thin-film transistors. It enables pure blacks, high contrast ratios, and, in LTPO variants, adaptive refresh rates.
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.
Dolby Atmos
Dolby Atmos is a spatial audio technology that enables three-dimensional sound reproduction. It is frequently identified in consumer devices as an audio feature or tuning brand, often in combination with other specifications such as Hi-Res Audio.
Wi-Fi 6 (802.11ax)
Wi-Fi 6, designated as the 802.11ax standard, is the generation of the 802.11 family that operates in the 2.4 GHz, 5 GHz, and 6 GHz bands, configured in a tri-band scheme alongside the other revisions of the family.
IP68 (Ingress Protection)
IP68 is an ingress protection rating indicating that a device is dust-tight (level 6) and resistant to water immersion up to 1.5 metres for 30 minutes (level 8). It is applied as a certification to electronic devices and consumer equipment.
Qualcomm Snapdragon 6 Gen 3
The Qualcomm Snapdragon 6 Gen 3 is a system-on-chip (SoC) designed by Qualcomm, identified as the primary chipset in mid-range mobile devices.
4K Video Recording
The ability of a device to capture video at 4K resolution, typically limited to 30 frames per second based on technical specifications.
Cortex-A55
The Cortex-A55 is an ARM architecture processor core designed for high energy efficiency. It is commonly used in multi-core configurations, such as four-core clusters operating at 1.8 GHz, to balance performance and power consumption in mobile devices.
Cortex-A78
The Cortex-A78 is a 64-bit processor core architecture designed by Arm, characterized by its focus on performance and energy efficiency. It is commonly used in mobile and consumer devices as part of heterogeneous CPU configurations.
Fast Charging
Fast charging is a battery feature that allows electronic devices to recharge in significantly less time than standard charging, optimizing device availability.
GPS
A satellite-based global positioning system that determines geographic location by receiving signals from constellations such as GPS, GLONASS, Beidou, and Galileo.
Android 15
Android 15 is version 15 of the Android mobile operating system, identified as a software platform and operating system on compatible devices.
GPS Positioning System
GPS is a satellite navigation system that allows devices to determine their geographic location. In consumer technology, its presence indicates geolocation capabilities, often complemented by other global systems like GLONASS, Galileo, or BeiDou to enhance accuracy.
