If you request a replacement, they should be obligated to fulfill that request without issue. I believe the charge for a replacement is $29 through the end of the year. If you want to avoid issues outright, try scheduling a repair via phone call, or hit up a support agent over chat.Applecare+ is about to expire on my 7+ and I’d like to keep this phone for at least another year. Will they replace my battery or does it actually have to be under 80%?
