The Xiaomi Redmi K70 Ultra has a non-folding, non-rugged design measuring 160.4 mm in height, 75.1 mm in width, and 8.4 mm in thickness, with a total volume of approximately 101.19 cm³ and a weight of 204 g. It carries an IP68 rating, classifying it as waterproof and offering solid protection against dust and water ingress in everyday use.

The Xiaomi Redmi K70 Ultra features a 6.67″ OLED/AMOLED touchscreen with a resolution of 1220 x 2712 px and a pixel density of 446 ppi, paired with a 144Hz refresh rate and a 480Hz touch sampling rate for responsive input. The panel reaches a typical brightness of 4000 nits and supports both HDR10 and HDR10+ content, while Always-On Display and branded damage-resistant glass are not included.

The Xiaomi Redmi K70 Ultra is driven by the MediaTek Dimensity 9300 Plus chipset, fabricated on a 4 nm process with 22,700 million transistors and an octa-core CPU configuration running at 1 x 3.4, 3 x 2.85, and 4 x 2 GHz across 8 threads using big.LITTLE architecture with HMP support, though simultaneous multithreading is not enabled. It is paired with 24 GB of LPDDR5 RAM at 4800 MHz — the maximum supported amount — across 2 memory channels delivering up to 76.8 GB/s of bandwidth, alongside 1024 GB of internal storage and an 8 MB L2 cache plus 18 MB L3 cache. Graphics are handled by the integrated Arm Immortalis-G720 MC12 GPU clocked at 1300 MHz, supporting DirectX 12, OpenGL ES 3.2, and OpenCL 2, while the chip also integrates LTE. Benchmark results include an AnTuTu score of 2,253,454, a Geekbench 6 single-core result of 2302, and a multi-core result of 7547, with full 64-bit support throughout.

The Xiaomi Redmi K70 Ultra features a multi-lens rear camera system with three sensors at 50, 8, and 2 MP, backed by a CMOS sensor, optical image stabilization, and phase-detection autofocus for stills, along with continuous autofocus during video recording — though laser autofocus is absent. The main camera supports video recording at up to 4320 x 30 fps, slow-motion capture, timelapse, in-camera panoramas, HDR mode, burst shooting, touch autofocus, and manual controls for exposure, ISO, focus, and white balance, while manual shutter speed, RAW output, and 360° panorama are not available. Two flash LEDs are present, though there is no dual-tone or RGB configuration. On the front, a single-lens 20 MP camera handles selfies without a dedicated flash.

The Xiaomi Redmi K70 Ultra runs Android 14 and includes a broad set of privacy controls, covering location access, camera and microphone permissions, clipboard warnings, and app tracking blocking, though cross-site tracking blocking, Mail Privacy Protection, and Wi-Fi password sharing are absent. On the usability side, it supports dark mode, extra dim mode, dynamic and manual theme customization, customizable notifications, a media picker, full-page screenshots, split-screen multitasking, picture-in-picture, sharing intents, widgets, a child lock, and multi-user support, while focus modes, app offloading, Quick Start, and PC mode are not available. The system also offers on-device machine learning, offline voice recognition, voice commands, device tracking, and the ability to play games during downloads, though direct OS updates from the vendor are not provided.

The Xiaomi Redmi K70 Ultra houses a non-removable rechargeable 5500 mAh battery with a built-in level indicator and supports wired fast charging at 120W, with a charger included in the box. Wireless charging is not available on this model.

The Xiaomi Redmi K70 Ultra includes stereo speakers but omits a 3.5 mm headphone jack, so wired audio requires an adapter or USB-C headphones. Bluetooth audio codec support is limited, with no aptX, aptX HD, or aptX Adaptive on board.

The Xiaomi Redmi K70 Ultra supports 5G connectivity and accommodates two SIM cards, with download speeds of up to 10,000 Mbit/s and upload speeds of up to 7,000 Mbit/s. Wi-Fi coverage spans Wi-Fi 4 through Wi-Fi 7 (802.11n, ac, ax, and be), and Bluetooth 5.4 is on board alongside NFC and a USB Type-C port, though there is no external memory slot. For navigation, the device includes GPS with Galileo support, a compass, a gyroscope, and an accelerometer, while a barometer is absent. Security is handled by a fingerprint scanner, with no 3D facial recognition or iris scanner present, and the phone also features an infrared sensor. Crash detection, emergency SOS via satellite, a heart rate monitor, and a stylus are not included.

The Xiaomi Redmi K70 Ultra includes a video light to assist with recording in low-light conditions, while the display is flat rather than curved and does not use sapphire glass.
