how much would you say is a reasonable amount to pay for a phone, and how often do you buy one?

@jacqueline Paid around £150 for my current phone in 2022 after dropping and smashing my previous one.
Phone is still working ok so might not swap it for another year or two.

2015 - £128
Bought a Wiley Fox which survived 7 years till I dropped it.

2014 - £157
HTC One - Looks like that one broke about 18 months later
