Hi, I'm not eligible for a 6s battery replacement, but I've recently been having some problems. Phone shutting off at around 15%, battery draining 1% per minute while doing nothing strange. All while some months ago I could use Waze with screen on for an hour with only 15% battery drop. Also I used to be able to use my phone for 2 days, now I'm struggling with 1 day, modest use. Edit: also strange, yesterday I looked in the battery settings, and the Phone app showed slightly over 50% use with audio, 1 minute on screen. Are this the problems the eligible iPhone 6s users are getting? Or is it something else entirely?
