The telephoto has a 1/1.56-inch sensor, 3.2x optical zoom, OIS and 12cm telephoto macro. A 50MP ultrawide covers 102° and focuses at 5cm. Video goes up to 8K at 30fps and 4K at 120fps. The 50MP front camera records 4K at 60fps.

Battery and charging

The 8,500mAh battery, with a rated minimum of 8,350mAh, is one of the largest in any flagship. It charges at up to 100W wired and 50W wireless. The phone can also power other devices through 27W reverse wired charging and reverse wireless charging. For heavy users, this battery should comfortably last more than a full day.

Connectivity

You get dual Nano-SIM 5G, Wi-Fi 7, Bluetooth 6.0, NFC, an infrared remote and USB 3.2 Gen 1. Navigation supports BeiDou, GPS L1 and L5, Galileo, GLONASS, QZSS and NavIC. A 3D ultrasonic fingerprint sensor sits under the display. Audio is a step up from the 18 Pro, with triple speakers that are Hi-Res Audio certified and support Dolby Atmos.

Tips for new owners

Use the 2.9-inch rear screen to take high-quality selfies with the 200MP main camera. Try 8K video only when you need it, because the files are very large. Turn on the privacy screen for banking and messaging in public places. Keep a 100W Xiaomi charger at home to get the fastest top-ups. Finally, install HyperOS updates as they arrive for camera and performance improvements.
