Be careful with the F2 Pro, many people have had issues with the charging port where it stops taking charge and leaves you with an expensive brick.
All very true, I was talking about in comparison with the F2 really
You'd miss out on an AMOLED display, 5G and a faster and more efficient chip. Also the F3 is a lot lighter and slimmer (even with the provided case on it) than the X3 Pro. I also have the standard X3 and it is bulky and noticeably heavier. But if non of those things matter, then the X3 Pro is ofcourse a good buy
the X3 Pro has a headphone jack, similar chip, I know the screens are different class but it's £100 cheaper if you aren't bothered by the screen quality.
The 6 Gig version is £299 on Friday. POCO F3 | 5G https://mobile.mi.com/uk/app/poco-f3/?utm_channel=social&utm_medium=clipboard
