Xiaomi Redmi K80

The Xiaomi Redmi K80 has a non-folding, standard-form design measuring 160.3 mm tall, 75 mm wide, and 8.1 mm thick, with a total volume of 97.38 cm³ and a weight of 206 g. Its build does not qualify as rugged, but it does carry an IP68 Ingress Protection rating, meaning the device is certified waterproof against dust and water immersion under standard test conditions.

The Xiaomi Redmi K80 features a 6.67″ OLED/AMOLED touchscreen with a 1440 x 3200 px resolution and a pixel density of 526 ppi, paired with a 120Hz refresh rate and a 480Hz touch sampling rate for responsive input. Typical brightness reaches 1800 nits, and the panel achieves a contrast ratio of 5,000,000:1, while HDR10, HDR10+, and Dolby Vision are all supported for wide-format content compatibility. An Always-On Display mode is available, and the screen is protected by Gorilla Glass Victus. The device does not include a secondary screen.

The Xiaomi Redmi K80 is driven by the Qualcomm Snapdragon 8 Gen 3 system-on-chip, built on a 4 nm process with an 8-thread CPU configuration using big.LITTLE and HMP architectures, and clock speeds spread across cores at 3.3, 3.15, 2.96, and 2.26 GHz, all within a 12.5W TDP envelope. Graphics are handled by the integrated Adreno 750 GPU running at 900 MHz with 3 execution units, supporting DirectX 12, OpenGL 3.2, OpenGL ES 3.2, and OpenVG 1.2, as well as OpenCL 2, and capable of driving one display. The chip also integrates LTE, TrustZone security, and full 64-bit support. On the memory side, the device ships with 16 GB of DDR5 RAM at 4800 MHz across two channels, a maximum supported memory amount of 24 GB, a maximum bandwidth of 76.6 GB/s, 1 MB of L2 cache, and 12 MB of L3 cache, while internal storage reaches 1024 GB alongside an eMMC 5.1 interface. Benchmark results include an AnTuTu score of 2,035,700, Geekbench 6 single-core and multi-core scores of 2213 and 7325 respectively, and a 3DMark Steel Nomad result of 1662.

The Xiaomi Redmi K80 features a dual-lens rear camera system combining 50 MP and 8 MP sensors, both using CMOS technology without a back-illuminated sensor, and supported by optical image stabilization, phase-detection autofocus, touch autofocus, and continuous autofocus during video recording, though laser autofocus is not present. The main camera can record video at up to 4320p at 24 fps and supports slow-motion capture, while shooting modes include HDR, burst, panorama, and timelapse; manual controls cover exposure, ISO, focus, and white balance, though manual shutter speed and RAW output are not available, and optical zoom stands at 0x. Illumination is provided by a dual-tone LED flash with two LEDs, while 360-degree panorama, HDR10 recording, Dolby Vision recording, and 3D photo or video capabilities are not supported. On the front, a 20 MP single-lens camera is present in a standard position — not under the display — and does not have its own LED flash.

The Xiaomi Redmi K80 runs Android 15 and includes a broad set of privacy controls, covering clipboard warnings, location privacy options, and camera and microphone access management, though Mail Privacy Protection and cross-site tracking blocking are not present. App tracking can be blocked, and on-device machine learning is supported, while OS updates do not come directly from the vendor. The software experience is highly customizable, with theme customization, dynamic theming, dark mode, an extra dim mode, customizable notifications, and widget support all available, whereas focus modes and Quick Start are not included. Productivity features include split-screen multitasking, Picture-in-Picture, full-page screenshots, a media picker, sharing intents, app offloading, the ability to play games while they download, and multi-user support, though the device cannot function as a PC. Offline voice recognition and voice commands are supported, as are phone tracking, a child lock, and Live Text for selecting text within images; Wi-Fi password sharing is not available.

The Xiaomi Redmi K80 is equipped with a 6550 mAh rechargeable battery that is non-removable and does not support wireless charging. Wired fast charging is available at 90W, and a charger is included in the box. A battery level indicator and an ultra power-saving mode are both present for day-to-day power management.

The Xiaomi Redmi K80 includes stereo speakers but omits a 3.5 mm headphone jack and does not have a built-in radio. For wireless audio, it supports a strong range of Bluetooth codecs including aptX, aptX HD, aptX Adaptive, and LDAC, though aptX Lossless is not available.

The Xiaomi Redmi K80 supports 5G cellular connectivity and accommodates two SIM cards, with download speeds reaching 10,000 Mbit/s and upload speeds up to 3,500 Mbit/s. Wi-Fi coverage spans Wi-Fi 4, 5, 6, 6E, and 7, while Bluetooth 5.4 and NFC are also on board. The device connects via USB Type-C at USB 2.0, but does not include an external memory slot, HDMI output, or DLNA certification. Onboard sensors include a gyroscope, accelerometer, compass, GPS with Galileo support, and an infrared sensor, while a barometer, heart rate monitor, ANT+, motion tracking, and optical tracking are absent. Security is handled through a fingerprint scanner, though 3D facial recognition and an iris scanner are not present, and no stylus is included. Emergency SOS via satellite, crash detection, and a built-in projector are likewise not featured.

The Xiaomi Redmi K80 includes a video light for recording in low-light conditions. The display is flat rather than curved, and neither sapphire glass nor an e-paper display are part of the design.
