Xiaomi Redmi Turbo 4 Pro (256GB / 12GB RAM)

The Xiaomi Redmi Turbo 4 Pro has a non-folding, standard-form design measuring 163.1 × 77.9 × 8 mm with a volume of 101.64 cm³ and a weight of 219 g. It carries an IP68 Ingress Protection rating, confirming full waterproof capability under standardized conditions. The build is not classified as rugged, meaning it does not include reinforced construction beyond the water resistance certification.

The display is a 6.83″ OLED/AMOLED touchscreen with a resolution of 1280 x 2772 px and a pixel density of 447 ppi, delivering a sharp and vibrant visual output. It operates at a 120Hz refresh rate and an exceptionally high touch sampling rate of 2560Hz, ensuring responsive input handling. Typical brightness is rated at 1800 nits, and the panel supports HDR10, HDR10+, and Dolby Vision for broad high-dynamic-range compatibility. Always-On Display is available, while there is no secondary screen and no branded damage-resistant glass coating.

The device is powered by the Qualcomm Snapdragon 8s Gen 4 system-on-chip, built on a 4 nm process with an 8-thread CPU configuration using big.LITTLE technology across four clock groupings — 1 x 3.21 GHz, 3 x 3.01 GHz, 2 x 2.8 GHz, and 2 x 2.02 GHz — and a TDP of 12.5W. It comes with 12GB of DDR5 RAM running at 4800 MHz, supporting up to 24GB maximum, alongside 256GB of internal storage and a maximum memory bandwidth of 76.8 GB/s. Graphics are handled by the integrated Adreno 825 GPU clocked at 1150 MHz with 3 execution units, supporting DirectX 12, OpenGL 3.3, OpenGL ES 3.2, and OpenCL 2, driving a single display. The chipset includes integrated LTE, TrustZone security, multithreading support, and 64-bit architecture, while cache is split across 6 MB L2 and 8 MB L3. Benchmark results stand at 2,406,698 on AnTuTu, with Geekbench 6 scores of 2154 single-core and 6880 multi-core.

The rear camera system uses a dual-lens setup with sensors at 50 MP (f/1.5) and 8 MP (f/2.2), both on a CMOS sensor array, with optical image stabilization and no optical zoom. Autofocus options include phase-detection and touch autofocus for photos, as well as continuous autofocus during video recording, though laser autofocus is not present. Video capture reaches 4K at 60 fps (2160p), with slow-motion recording supported, while HDR10 and Dolby Vision recording are not available. The flash setup consists of 3 LEDs without dual-tone or RGB configurations. Manual controls cover exposure, ISO, focus, and white balance, but manual shutter speed and RAW shooting are not supported; burst mode, HDR, panorama, and timelapse are all available. The 20 MP front camera sits at f/2.2 in a single-lens arrangement, without an under-display position or a front-facing flash, and does not support 360° panorama or 3D photo and video capture.

The device 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 available. App tracking can be blocked, and on-device machine learning is supported. Customization options include theme customization, dynamic theming, dark mode, and an extra dim mode, while focus modes are absent. Usability features span split-screen multitasking, Picture-in-Picture, a media picker, full-page screenshots, Live Text, customizable notifications, widgets, sharing intents, child lock, multi-user support, app offloading, and the ability to play games while they download. Voice commands and offline voice recognition are both supported, as is device position tracking, while Wi-Fi password sharing, Quick Start, and PC mode are not. OS updates are not delivered directly from the platform vendor, and the operating system is free and open source.

The device is fitted with a 7550 mAh rechargeable, non-removable battery that supports fast charging at 90W, and a charger is included in the box. Wireless charging is not available. A battery level indicator and an ultra power-saving mode are both present, the latter offering extended standby by restricting the display and background activity when charge is critically low.

The device includes stereo speakers and supports aptX for Bluetooth audio, though aptX HD, aptX Adaptive, aptX Lossless, and LDAC are all absent. There is no 3.5 mm headphone jack and no built-in radio.

The device supports 5G cellular connectivity and accommodates two SIM cards, with download speeds reaching 4200 Mbits/s and upload speeds of 3500 Mbits/s. Wi-Fi covers versions 4, 5, 6, and 7 (802.11n/ac/ax/be), and Bluetooth 5.4 is on board alongside NFC. The USB interface is Type-C running at USB 2.0 speed, and there is no external memory slot, HDMI output, or DLNA certification. Sensors include a gyroscope, accelerometer, compass, GPS with Galileo support, an infrared sensor, and a fingerprint scanner, while a barometer, heart rate monitor, iris scanner, and 3D facial recognition are all absent. ANT+, crash detection, satellite SOS, motion tracking, optical tracking, and a built-in projector are likewise not featured, and no stylus is included.

The device includes a video light for recording in low-light conditions, while the display is flat rather than curved and uses neither sapphire glass nor an e-paper panel.
