True of any rechargeable battery as it approaches its consumed level. Battery replacement is $69 USD+tax on newer phones. If faulty warranty covers, test determines. If you have AC+ your covered. Some people go through a battery in a year or so just through sheer heavy use. Others go years and only get just below 90%.
Today I got my 3 year old 11 Pro Max replaced for free. As the title says today Apple replaced my 3 year old phone for a new one (same model). Long story short I got the battery of my old phone replaced 6 months ago, yesterday it came in contact with some water and all cameras had condensation in them and for some reason the Face ID stopped I have an iPhone 11 pro. For nearly 10 months, my battery health remained at 85%. Earlier this year I thought my battery will be needing replacement soon. And I was hoping for a replacement within warranty. Sadly earlier this month my warranty expired. Either way they will give exchange it for a similar iphone 11 with a fresh battery. When I had mine done at the apple store it took 45mins. I scheduled an appt at Best Buy and they didn't even have a battery and it would take days to get one in. Make an appointment in the Apple Support app and then expect 1-2 hours. I wrote to iFixit and they mailed me another fix kit with the replacement battery including the waterproof adhesive. It could just be that my first battery was at slightly less than 100% and the battery was good apart from that. I will update after installing the replacement. Hx_5 • 1 yr. ago. nROd.
