iPhone 6S, had the battery replaced on Dec 29, 2018. Old battery was at 84% health so I decided to take advantage of the low price.
Just this week it's suddenly gone from totally normal to completely unusable. It'll drain from 90% to zero in 50 minutes while only listening to music, no other apps open, and all background services suspended. It also charges abnormally fast, from 0 to full in under an hour.
All of this happens without it heating up at all.
The battery only has 47 cycles on it according to Apple's diagnostics, but the health thing says it's at 93%.
I did a DFU restore at the Apple store, in front of the manager, and no change. But the manager says if their computer reports the battery is fine, they can't do anything about it and I'll have to pay out of pocket for a new one. The manager also insists that it's probably not the battery at fault so I should just buy a new phone. Of course.
I showed the manager to her face that the battery was dropping one percent every five seconds and still no concession.
Replacement batteries have a 90-day warranty, but apparently that only applies if the diagnostics detect it's below 80% health within that 90 days.
I suspect a bad and swollen cell because at the same time this started, I noticed pressure ripples in my screen right where the top right corner of the battery is. That wasn't happening before.
My phone was purchased brand new in July 2017, so it's not even two years old. I didn't get AppleCare because my old iPhone 5 was still running perfect at five years of age and I've never known anyone with a hardware defect.
What can I do?
