Explained concepts and technologies
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.
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.
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.
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.
Accelerometer
A sensor component that measures acceleration, listed alongside other sensors such as the gyroscope and proximity sensor.
Gyroscope
A motion sensor that measures angular rotation, listed as a standard component in electronic device technical specifications.
45W Fast Charging
45W Fast Charging is a power specification for electronic devices, typically smartphones, that allows for faster battery recharging than standard rates by using compatible adapters and cables.
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).
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.
4K Video Resolution
4K is a video resolution standard that denotes a pixel density significantly higher than Full HD. Its presence in a product indicates that the device can record or play back video sequences at that resolution.
Fingerprint Sensor
A biometric security component integrated into electronic devices for user authentication via unique skin pattern recognition.
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.
LTE (Long-Term Evolution)
LTE is a 4G cellular technology standard positioned in the evolutionary sequence GSM → HSPA/WCDMA → LTE → 5G. Its presence in a product indicates support for fourth-generation mobile communications.
Bluetooth 5.4
Bluetooth 5.4 is a version of the wireless standard that improves connection speed, range, connectivity, and device discoverability.
