After almost two years, I finally damaged by iPhone X. Ironically after dropping it many times, this time it literally fell from a couple inches while I was underneath my car. The back glass doesn't look too bad... from a purely cosmetic standpoint it's probably not worth replacing. However, I take this phone in water a lot, and while I'm not swimming with it or anything crazy, it does get relatively wet. I'm wondering if I should pay the $99 (with Applecare, which the other day I was joking I had paid for unnecessarily) and replace the back glass. I don't actually know if that would help, or if taking the phone apart might make it LESS water resistant. I figured I'd pay an extra $49 and have them replace the battery while it's in there, that way it can easily last another year or two until Apple releases a phone that makes me want to upgrade! Your advice please?
