is it worth getting 12 mini in 2026?

so currently i own a OnePlus 13R, the phone is good but in typical OnePlus fashion the notifications are always delayed or sometimes complete miss. So I was planning on selling my phone and get iphone 12 mini second hand, I'm getting one for 16k rupees($170) in pristine condition but battery health is 79%. So should I get an almost 6yr old phone in 2026 or maybe look for newer models?
