Knowledge
Explained concepts and technologies
Phase-Detection Autofocus (PDAF)
PDAF is the designation for an autofocus system based on phase detection. In the available evidence, it is listed for both a wide camera and a telephoto camera, alongside optical image stabilization (OIS).
Near-field communication (NFC)
NFC is a feature stated in the available evidence for the product. Its presence is documented as a listed characteristic, but the sources do not describe uses, compatibility, or technical specifications.
Periscope telephoto lens
A periscope telephoto lens is an optical module used in mobile devices that folds the light path via an internal prism or mirror, achieving a real optical zoom (typically 3×) and a 71 mm equivalent focal length without increasing device thickness. It incorporates optical image stabilization (OIS) and, in recent configurations, a 50 MP sensor.
Leica Summilux
Leica Summilux is a designation associated with Leica camera lenses in the available evidence. Its presence identifies the advertised lens or lenses, but does not by itself establish specifications or the performance of the complete product.
Optical zoom
Optical zoom is a camera mechanism that magnifies the field of view through lens elements, expressed as a multiplier (e.g., 2x) indicating the real magnification factor on the captured image.
Wired Fast Charging
A battery-recharging technology that uses a physical cable connection to deliver elevated power levels, such as 90 W, negotiated between charger and device to significantly reduce charging time.
Qualcomm Snapdragon 8 Elite Gen 5
A mobile platform identified as the Qualcomm Snapdragon 8 Elite Gen 5 processor; one source also associates it with a 3 nm designation.
CIPA image stabilization rating
An image-stabilization performance designation expressed in CIPA stops; the available evidence cites a CIPA 6.5 rating for a stabilization engine and for a telephoto camera with OIS.
Reverse wired charging
Technology that allows a device to act as a power source through a physical cable, with a 5 W output power.
Bypass charging
A charging mode that uses the USB Power Delivery (PD) protocol to power the device directly, bypassing the battery as an intermediate energy node. It is associated with high-power wired charging (90 W) and can operate in a reverse (reverse wired) direction in mobile devices.
PDAF (Phase Detection Auto Focus)
An autofocus technique that determines focus distance by measuring the phase difference between two displaced images, enabling fast and precise focal-plane adjustment. Its dual-pixel variant integrates phase detection directly into the sensor's pixel matrix.
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.
Silicon-Carbon Anode
A battery chemistry in which the negative electrode combines silicon and carbon, designated as 'Silicon-Carbon' or 'Silizium-Kohlenstoff' in product documentation.
IP68 / IP69 Protection
IP68 and IP69 are dust and water resistance ratings defined by the IEC 60529 standard. They indicate that a device offers complete protection against dust ingress (digit 6) and resistance to submersion or high-pressure water jets (digits 8 and 9). They are commonly listed alongside military certifications such as MIL-STD-810H on rugged products.
Ultrasonic fingerprint sensor
A fingerprint-based biometric authentication method that uses ultrasonic technology and is positioned beneath the device display.
