Anyone recommend an upgrade

May 2020 and still using the nexus 6. It's been an amazing phone and still runs fantastic.

I have recently noticed though, that occasionally the phone switches off when I try to use the camera and the battery is around 50%.

I've had it pretty much since launch so it's services me well.

This time around I'm looking for a budget android phone.

Can anyone recommend a good phone in the budget range?
