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

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:

Xiaomi Mi Mix 2S vs. Mi Mix 2

The Mi Mix 2S will go on sale in China starting later this week for the equivalent of $530 for the model with 6GB of RAM and 64GB of storage. 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. In the meantime, let me know what you guys think of the Mi Mix 2S in the comments.

  • Camera will be the only real difference. Looks like the larger pixels and lower aperture will make for better pictures on the S, at least on paper. Everything else will be a wash. 845 vs 835 is going to be an almost negligible difference, only noticeable if the devices launch the same app side by side.
