Best option for mobile phone

[daviddusty]

As an Xray core developer, if you want to create a CPU‑ and battery‑friendly config for your Android or iOS phone, which one would be your choice?

1. Forget about UDP‑based connections. I only have a TCP open port on my server.
2. There is no censorship system between me and the ISP, so it doesn't need to be firewall‑resistant.
3. I want to use mux: enabled with concurrency: 2

VLESS + WS + TLS?
VLESS + TCP + REALITY?
VLESS + XHTTP + TLS?
Shadowsocks + uot:true?
... ?
... ?

Thank you
