Need help buying a phone

Is it worth buying iPhone 15 pro for 54k? Battery health is 84%.

I have a 17 pro however due to some technical issues that is not with me and it might take a while to get my device back. I need another device to manage my communication and the one which fits my budget is 15pro. I need a spare device for just in case. Can get a battery replacement if needed next year or so.

Always used iOS, so can’t use any other operating system.
