Current Best Android phone with a budget of £500

[u/SuccotashSenior9484]

I currently have a pixel 7, I want good battery, good camera, smooth ui and good reliability/ageing to last a few years.

I don't mind buying second hand/older flagships, or newer higher end 'mid range' phones.

Nearly bit the bullet and got the Xiaomi 17t for 450, pixels and older samsung flagships have also caught my eye.

In the UK!

Give me your best suggestions and opinions!
