Which is better, Apple xs or Xiaomi 10?

Xs, I didn't. I have xsmax and Xiaomi 10, each with its own advantages and disadvantages. Xiaomi 10 battery is bigger and has better standby. Dual speakers are better than xsmax's, and the camera body is heavier to take pictures (two 200w cameras). Xsmax can also be upgraded from ios 12 to ios 13 before standby upgrade. Standby is obviously reduced, and the screen display effect is good. I don't know how the game experience is (Xiaomi 10 plays the glory of the king often 460).

It depends on your personal preference. It takes a while to get used to ios and Android.
