Using replacement battery kit on phone identified as water damaged
I’m interested in using iFixit’s battery replacement kit for my iPhone 6s. When I took it to Best Buy for the $29 deal last year, they refused to do the service based on the water damage indicator showing pink (I dropped it in the river for a couple of seconds about 1.5 years ago).
I’ve never had any issues stemming from the water damage (that I know of), but my battery could use replacement. My question is whether or not it’s a good idea to use this kit to do it myself. I’ve seen other posts that recommend doing a good cleaning using isopropyl alcohol before battery replacement. Given that I’m completely new to any phone repair, is it worth buying the kit? Any risk of me catching my phone on fire? Battery health maximum capacity is at 83%. Thanks for any advice.
