Xiaomi Redmi Turbo 4 Pro

The Xiaomi Redmi Turbo 4 Pro has a non-folding, standard-form design measuring 163.1 mm tall, 77.9 mm wide, and 8 mm thick, with a total volume of 101.64 cm³ and a weight of 219 g. It carries an IP68 ingress protection rating, classifying it as waterproof, though it does not feature a rugged build in the traditional sense. The device is not designed to fold, making it a conventional candybar-style smartphone.

The Xiaomi Redmi Turbo 4 Pro features a 6.83″ OLED/AMOLED touchscreen with a resolution of 1280 x 2772 px and a pixel density of 447 ppi, producing a sharp and detailed image across its large panel. Typical brightness is rated at 1800 nits, and the display refreshes at 120Hz with an exceptionally high touch sampling rate of 2560Hz for responsive input. It supports HDR10, HDR10+, and Dolby Vision for wide-format content compatibility, and includes an Always-On Display mode. The screen does not use branded damage-resistant glass and there is no secondary display.

The Xiaomi Redmi Turbo 4 Pro is driven by the Qualcomm Snapdragon 8s Gen 4 system-on-chip, fabricated on a 4 nm process and configured with 8 threads across a big.LITTLE CPU layout running at speeds of up to 3.21 GHz, alongside an Adreno 825 GPU clocked at 1150 MHz with 3 execution units and support for a single display. The chipset includes integrated LTE and integrated graphics, supports 64-bit processing and multithreading, and is backed by ARM TrustZone security. The device ships with 16 GB of LPDDR5 RAM at 4800 MHz — expandable to a maximum of 24 GB — and 1024 GB of internal storage, with a maximum memory bandwidth of 76.8 GB/s, a 6 MB L2 cache, and an 8 MB L3 cache. Graphics API support covers DirectX 12, OpenGL 3.3, OpenGL ES 3.2, OpenVG 1.2, and OpenCL 2, while the chip carries a TDP of 12.5 W. Benchmark results place the AnTuTu score at 2,406,698, with Geekbench 6 returning 2,154 in single-core and 6,880 in multi-core testing.

The rear camera system on the Xiaomi Redmi Turbo 4 Pro is a dual-lens setup combining a 50 MP sensor at f/1.5 and an 8 MP sensor at f/2.2, both using CMOS technology without a back-illuminated sensor. It supports optical image stabilization, phase-detection autofocus for stills, continuous autofocus during video, and touch autofocus, but does not include laser autofocus. Manual controls extend to exposure, ISO, focus, and white balance, though manual shutter speed is not available. The main camera records video at up to 2160p at 60 fps and supports slow-motion recording, while HDR mode, burst shooting, panorama, and timelapse are all present; HDR10 and Dolby Vision recording are not supported. Flash is provided by three LED units, though the setup is neither dual-tone nor RGB. The 20 MP single-lens front camera sits in a conventional position above the display — not under it — at f/2.2, with no front-facing flash. Neither the front nor rear system offers optical zoom, RAW capture, 360-degree panorama, or 3D photo and video recording.

The Xiaomi Redmi Turbo 4 Pro runs Android 15 and includes a broad range of software features covering both usability and privacy. On the privacy side, it offers clipboard warnings, location privacy options, camera and microphone access controls, and the ability to block app tracking, though Mail Privacy Protection and cross-site tracking blocking are absent. Customization options include theme customization, dynamic theming, dark mode, and an extra dim mode, while focus modes and Wi-Fi password sharing are not available. The OS supports split-screen multitasking, picture-in-picture, full-page screenshots, a media picker, customizable notifications, sharing intents, widgets, and the ability to play games while they are still downloading. It also includes on-device machine learning, offline voice recognition, voice commands, live text selection from images, app offloading, a child lock, multi-user support, battery health check, and device position tracking. Direct OS updates from the vendor are not provided, and the device cannot function as a PC or use Quick Start.

The Xiaomi Redmi Turbo 4 Pro houses a 7550 mAh rechargeable battery that is not removable. It supports wired fast charging at 90W, and a charger is included in the box, though wireless charging is not available. A battery level indicator is present, and the device also offers an ultra power-saving mode that restricts the display and functionality to extend runtime when charge is critically low.

The Xiaomi Redmi Turbo 4 Pro includes stereo speakers and supports aptX for Bluetooth audio, but does not offer aptX HD, aptX Adaptive, aptX Lossless, or LDAC. There is no 3.5 mm headphone jack and no built-in radio.

The Xiaomi Redmi Turbo 4 Pro supports 5G cellular connectivity and accommodates two SIM cards, with download speeds reaching 4200 Mbit/s and upload speeds up to 3500 Mbit/s. Wi-Fi coverage spans four generations — Wi-Fi 4 (802.11n), Wi-Fi 5 (802.11ac), Wi-Fi 6 (802.11ax), and Wi-Fi 7 (802.11be) — while Bluetooth 5.4 handles short-range wireless. The device uses a USB Type-C port running USB 2.0 and includes NFC, a fingerprint scanner, an infrared sensor, GPS with Galileo support, a gyroscope, an accelerometer, and a compass. There is no external memory slot, HDMI output, barometer, heart rate monitor, ANT+ support, or DLNA certification, and the device does not include a stylus, a built-in projector, crash detection, or emergency SOS via satellite. Biometric authentication does not extend to 3D facial recognition or an iris scanner, and motion and optical tracking are also absent.

The Xiaomi Redmi Turbo 4 Pro includes a video light for use during video recording, while its display is flat rather than curved and uses neither sapphire glass nor e-paper technology.
