I had to go to 3 different Apple stores across the country from West Coast to New York and back to finally get my iPhone 11 pro max 512 GB completely replaced after updating to iOS 16. I had constant battery draining even after two battery replacements at the Apple Store. When I went to the battery health settings it went down 10% after every battery replacement in less than a week, sometimes only days or hours!
Lots of overheating, and sluggish performance, sometimes the flashlight wouldn't work and the brightness dimmed. There were 2 random boot loop events for hours, one of the events happened during my New York trip leaving me stranded, ruining the entire day I had planned! It took a lot of convincing for Apple to finally replace my phone completely. Only after torturing me with numerous Apple 'Genius' visits, putting me through the wringer of condescending junior techs, trying to lecture me on what I was doing wrong, and endless diagnostics that came up with 'nothing wrong' over and over again.
I kept using the 'controversial' term: 'planned obsolescence' over and over again. Thankfully I finally got my replacement iPhone after two attempts, one at Grand Central Station Apple Store. They had one left, and they were going to do the replacement for free but 'the system' wanted to REPO my phone instead (send my iPhone in for more endless, redundant, never-ending, useless diagnostics) they couldn't override it even with the manager override codes. So I went back home after completing my New Year's New York Trip.
After reading the notes on my case and talking to me over the phone, the Manager at the Apple Store from my hometown agreed to do me a solid and 'pull strings' to get me a replacement at 0 costs to me. It was out of warranty, even for apple care, being over 3 years old. Thank you **** and **** for your wonderful service!
My new iPhone 11 Pro Max 512 GB is now sitting happily and healthily on iOS 15.5. I installed TVOS OTA Blocker as I wait for Apple to fix their OS or maybe I'll never update or purchase an iPhone again.
