IPhone 6s battery exploded (more like expanded or inflated) can I get any refund for it?

I've had my iPhone 6s for three or more years and at one point in 2018 I got the battery replaced. A couple months ago, not even a year after I had Apple replace the battery it started dying fast then soon enough it crashed and a day after that I couldn't get it to turn on without it crashing again. So I got another phone and stored that one away in a drawer. A couple months later I pull out the phone and the battery looks like it's been blown up and the screen and back are spilt apart.
Is there anything Apple could do to refund me for it or warranty?
