Here's the launch keynote, though note that it's over two hours long and that there are some repeated bits - plus the presentation itself doesn't really start until 00:48:30!
For simplicity, I'll just cover the top two picks from the range. The Redmi Note 11 Pro 5G has a Snapdragon 695, a 6nm chip, with 6GB or 8GB of LPDDR4X RAM and 64GB or 128GB of UFS 2.2 storage. There's a hybrid card tray, meaning that you can put in a microSD card instead of a second SIM. The Redmi Note 11 Pro (4G) has a Helio G96 chip instead, on an older 12nm process, with other specs largely the same. Both will launch with MIUI 13, which is based on Android 11.
Both have a 6.67” AMOLED 1080p display, 120Hz refresh rate, and supporting DCI-P3 wide color gamut. Gorilla Glass 5 protects the screen, while the phones are IP53 for dust and splash resistance. The main camera on the back of each is 108MP, 1/1.52” in size, with 9-in-1 pixel binning and - in theory - 3x smart-cropped zoom. Plus an 8MP ultrawide camera (118°) and a 2MP macro.
Happily the fingerprint readers are side-mounted capacitive, and there's an also welcome 3.5mm headphone jack, plus stereo speakers. Both models are powered by 5000 mAh batteries, which support 67W fast charging. Availability is February and I don't have UK pricing yet. Expect a range of £250-£350, depending on spec level and model.
