What else do you use the phone for? Unless you play games is it worth spending £500 on a phone?
A feature worth having is facial recognition - Although its not massively secure it allows unlocking when you have gloves on / wet and dirty fingers.
With the Xiaomi phones you will need to install the hidden settings app and remove a lot of the bloat that comes with the phones.
The phone I have has Dual SIM, although I don't use it! The only thing I don't like about it is you cant dim the torch light down like I can with the works Iphone and I have not worked out how to get google to control my house automation from the lock screen using voice...
Yeah I use it to do teams, and zoom meetings, which surprisingly require a lot of processing power, my current phone gets really hot and chews through the battery, 1x 30 min meeting can see the battery drain to 50%.
So really I want something that's dual SIM, more powerful than current phone, and can withstand some abuse and not just shatter even just looking at the floor which seems to be the case with curved phones and I phones.
I don't like cases as they bulk the phone out, but I am resigned that this is likely to be inevitable.
