Xiaomi Mi Mix 2S vs. Mi Mix 2: What's the difference?

The Mi Mix 2S is a mid-cycle refresh of the Mi Mix 2 featuring the Snapdragon 845, dual rear cameras, and wireless charging.

Xiaomi unveiled the Mi Mix 2 in China last September, with the phone featuring a ceramic back and smaller 5.99-inch display. The company is now introducing a mid-cycle refresh — the Mi Mix 2S — that shares the same design aesthetic while offering upgrades in several areas.

Although both phones look identical from the front, the Mi Mix 2S sports a lot of changes. Turn the phones around and you'll see a dual camera setup on the Mi Mix 2S — which offers AI-assisted scene selection. Then there's the internal hardware, with the phone featuring Qualcomm's latest Snapdragon 845 chipset.

Xiaomi also incorporated wireless charging into the device, and the company has introduced an affordable wireless charging mat that costs just $25. Here's a quick look at the differences between the two phones at a hardware level:

As of now, there's no word on availability outside the country. But with Xiaomi looking to solidify its position at the top of India's handset market, the phone should make its way to the subcontinent shortly.
