1) How about the battery life compare to iPhone X vs iPhone Xs vs iPhone Xr? So far I know that iPhone X have good battery life, but if compare to Xs and Xr?

2) The screen sharpness to read word or YouTube ? iPhone X vs iPhone Xr (for those come from iPhone X)

3) iPhone XS and Xr can really dual standby dual use for call and using data? Can both turn on data at the same time? I mean one can backup other if one at poor coverage area.

4) HK set dual physical SIM card more convenient or with the esim one? Most trusted and cheapest way to get it?

5) do you think worth to change iPhone X to iPhone Xr if considering of dual SIM card, battery life (some said iPhone XR has the best battery life ever in iPhone line , really).

Thank you
