The Xiaomi Mi Mix 4 is one of the most innovative smartphones Xiaomi has ever made, featuring a hidden under-display front camera that keeps the screen completely clean and uninterrupted. Launched in China under the Mi Mix series, the Mi Mix 4 marks Xiaomi's first foray into Camera Under Panel (CUP) technology — a breakthrough that makes the selfie camera invisible to the naked eye.
Xiaomi Mi Mix 4: Under-Display Camera and Key Features
The star attraction of the Mi Mix 4 is its 20-megapixel under-display front camera, powered by Xiaomi's proprietary Camera Under Panel (CUP) technology. Unlike punch-hole or notch designs, the camera sits beneath the 6.67-inch Full HD+ AMOLED display, delivering a truly full-screen experience. The display supports a 120Hz refresh rate, 10-bit TrueColor, HDR10+, Dolby Vision, and is protected by Corning Gorilla Glass Victus. Resolution stands at 1080x2400 pixels.
Under the hood, the phone is powered by the Snapdragon 888+ processor paired with up to 12GB of LPDDR5 RAM and up to 512GB of internal storage. An in-display fingerprint sensor handles biometric security, and the phone ships with Android 11-based MIUI.
For connectivity, the Mi Mix 4 includes 5G, 4G LTE, Wi-Fi 6, Bluetooth, GPS/A-GPS, and a USB Type-C port.
Xiaomi Mi Mix 4 Camera System
The rear camera setup is a triple-lens array headlined by a 108-megapixel HMX sensor with an f/1.95 aperture and Optical Image Stabilization (OIS). The second lens is a 13-megapixel periscope telephoto camera with support for up to 50x zoom. The third lens is an 8-megapixel ultra-wide-angle shooter. This versatile setup covers everything from sweeping landscape shots to highly detailed zoomed portraits.
Battery, Charging and Pricing
The Mi Mix 4 houses a 4500mAh battery with support for industry-leading 120W wired fast charging and 50W wireless charging. The phone weighs 225 grams.
Pricing in China starts at 4,999 Chinese Yuan (approximately Rs 57,400) for the 8GB RAM + 128GB storage variant. Other configurations include:
