Hello. I have a launch day iPhone X, with the battery health reading at 89%. There are 17 days left for the $29 battery replacement before the price increases. A few days ago, I was all for having the battery replaced. Now I’m wondering if I should have the battery replaced or wait for it to go under 80% and have it replaced before my AppleCare expires 11/1/19. I do want to add, that I will be upgrading to next year’s XS Max, whatever the name will be.
