Had my 6S battery swapped out by Apple near exactly 9 months ago now and tonight, after a very sudden loss of battery charge % - I got the full iOS <10.2 experience. Hello Unexpected Shutdown, my old friend. Needless to say, checking the battery page after the phone rebooted un-aided after 20 seconds, I'm being throttled. Battery health at 92% and I'm throttled to 600Mhz. Sure, I could disable it and deal with the erratic battery drops and shutdowns that will creep in at increasingly higher percentages, but is this really acceptable? During the throttling scandal, plenty came out in support of Apple saying that people with 'old' devices should expect the batteries to be degraded after 2+ years, that Apple was doing everyone a solid with the throttling. But 9 months? Is that the shelf life of an iPhone battery? They're not exactly user replaceable - so this then begs the question, is this the shelf life of an iPhone? Always kept my Apple devices for at least 2 generations and I've never had an issue like I have with this 6S. I'm thankful that I live in the UK and the consumer protection laws are there such that Apple is obligated to replace the battery as defective, but I know that not everyone is covered by such laws. Who knows, maybe I got a dud? But this behaviour being exactly what I experienced with this device before I had the battery swapped out doesn't give me much hope. Anyway, I'll be making a trip to the local Apple Store next week but thought I'd post this here as I'd been looking in the past for posts that reported what battery health was for people when they started getting throttled. I'm sure it varies wildly, but I was not expecting this to kick in at 92% health.
