Question about my “new” Apple iPhone 13, A2482, 128GB, Unlocked, Very Good Condition… - eviltoast

I’m very happy so far. This refurbished 13 is practically flawless, though it was listed in merely “very good” condition on eBay. It came with a one-year warranty serviced by Allstate & has a battery health rated at 88%. I guess that’s pretty good for a two-year-old phone? The 2019 XR (64GB with cracked screen) it replaced has just 80% battery life.

As is, my XR isn’t worth much. I saw a video showing how to replace the XR’s screen for <$40, including tools. Is it worth doing so? I figure it could be worth >$200 to somebody. (Similar w/warranty are $239 on eBay.) s should I just forget about it? Should I just forget about it? If I should repair it, should I also replace the battery at the same time to increase its value? Where can I get a good quality XR battery? I’m pretty handy, but I’ve never opened an iPhone!
