I went into my local Apple Store today and inquired a batter replacement for my iPhone 6+ (on iOS ver 10.3.3) due to its dying lifespan. First thing the Apple employee asked me was, did I call Apple support line first? On this number 1-800-275-2273. 1. Was I required to contact their phone service first like this employee stated? Or was I able to inquire it in-store? (Had a co-worker do his all in store without inquiring on the phone or online) Second, she asked me to scan the QR code with the stock iPhone app (to get the number for Customer Service line). I couldn't because it wasn't on iOS 11. Guess that's a new feature for iOS 11 or greater, built in QR code reader? 2. The employee said I needed to be on iOS 11. Did anyone on an iPhone 6+ get the $29 replacement battery on an iOS version prior to 11? Third, because she said I wasn't on iOS 11, she told me there was nothing wrong with my battery. She said, I need to be on iOS 11 because the replacement batteries are only serviced for devices on iOS 11. That sounded like a load of crap. Maybe a disgruntled employee or following manager at that specific store trying to lie to customers so they don't have to deal with battery replacement and send them to phone CS or online. I will give the employee the benefit of the doubt, but it didn't seem like the welcoming Apple service I expect from them. 3. Was she BSing me to try to upgrade to latest iOS? Or do I need to be on iOS 11 or later to get the battery replacement? Also, can the battery replacement be done all in store without calling the CS line? It might be the latest rule for that, but has anyone did so n the last 2-3 weeks confirm I need to call the CS line first in order to get a battery replacement? If I recall, the battery throttle came in iOS ver 10.2.1, and I am on 10.3.3. What gives? My iPhone 6+ is about 41% wear level with health capacity of 58% +/- 1%. Is my iPhone applicable for the $29 battery replacement? Or is there a certain criteria I need to be in to get that offer? What requirements are needed to make my iPhone 6+ eligible for the battery replacement? Hopefully I provided enough information for someone to comment/help on my issue. Thank you in advance!
