Approximately zero. And obviously, those would have been covered under warranty. The reason you haven't heard this before is that it didn't happen.
They weren't covered under my warranty.
Either the warranty expired -- in which case it isn't a "few months", or it was within the warranty period, in which case it is covered.

> it was about doing this without notice, and having internal tooling that would deny a replacement (even at full retail price) if the battery was above an arbitrary health threshold (but still low enough to cause throttling). Do you have a source for that? This would change my opinion on this story. Reminds me of hot coffee where it sounded a bit ridiculous until you got the full story.
> Do you have a source for that? This would change my opinion on this story. I can vouch for this. My iPhone 6 was under 2 years old and had 82% battery health according to the Apple diagnostics when I experienced the unexpected shutdowns. The shutdowns were frequent (at least once per day) and, because the phone had to be plugged in before it could be restarted, were incredibly frustrating. I took it to an Apple Sto…
It similarly showed 80+% battery health, but I showed them the battery charge history in Settings (dropped from 40% to 0% instantly) and they replaced it under warranty.
Happened a year and a half later, exact same scenario, and paid the ~$30 to get it replaced.
I suspect they didn't have any monitoring to detect or log the shutdowns at the time. But I find it extremely confusing why different Apple stores would have such different policies or manager discretion.

The reason for the lawsuits and bad PR wasn't that user experience was degraded, but that it was done in a way that was close to planned obsolesce. Apple had ways to avoid this.
There’s no other way to fix the spontaneous shutdowns though. And I will repeat that they should have told people it might slow their phone down.
Acting this way was a choice, which may have been fine with had Apple not denied the issue and allowed replacing bad batteries under warranty.

Technically speaking, they could have designed the battery differently so it's much more likely to last the full service life. Acting this way was a choice, which may have been fine with had Apple not denied the issue and allowed replacing bad batteries under warranty.
There's only so much you can do to make lithium batteries last forever. These days the phone tries to figure out when you need it charged by in the morning so it's not sitting on the charger at 100% for eight hours overnight, and this is supposed to help.
Worth mentioning here is that this wasn't just about the "sneaky" fix for battery degradation, it was about doing this without notice , and having internal tooling that would deny a replacement (even at full retail price) if the battery was above an arbitrary health threshold (but still low enough to cause throttling). Before Apple changed their tune, if you read about this, and went into an Apple store for a replace…
Hi, Battery engineer here at an electric vehicle company. The crux of it is this: when you draw high current from a small battery, the voltage will sag (1). The manufacturer has an on-board battery management system that MUST turn off the battery if it goes below a certain voltage threshold. As the battery ages, the sag effect increases significantly, up to 2-3x. Thus, when your phone clearly indicates say 20% batter…
you are saying that they don't know how to calculate battery percentage left?

I'm pretty sure they ran an exchange program for affected models of the 6s: https://www.usatoday.com/story/tech/2016/12/06/apple-says-ip...

It's true that battery degradation can't be avoided eventually; but there's a reason why these complaints are rarer on high-end Androids (Also low-end, but it's likely users have appropriately lower expectations for these).

That replacement program was for a different problem, not battery degradation per se but a manufacturing error; The throttling affected other models too (and replaced 6s batteries after enough time I guess).

The fix for this is simple. Appropriately size the battery when designing and manufacturing the device so that it is still capable of running the device a few years into it's lifetime, instead of a few months. The after the fact fix for this is also to not refuse to fix your defective devices when customers bring them in under warranty claims , and definitely to not lie about them not being defective . You don't make…
In my experience, which included managing and oversight of the operations/budgets for BlackBerry, iPhone and Android fleets with 10-50k devices, early battery death is usually accounted for by poor environmental conditions like temperature extremes. The AFRs didn't change in my experience much at all over time, except that legacy BlackBerries would get battery replacements.
The only outlier was failure rates for Samsung Galaxy phones, which was an operational issue (about 40% more failures if memory serves) -- NOT a defect or problem with the phone itself. They were mostly deployed to field workers operating out of cars or outdoors because Samsung allows a much broader operating range. Extreme cold especially would kick the crap out of the Samsung batteries, especially if they keeping them in outer pockets of winter coats or leaving them mounted to vehicles. Apple is conservative with battery management because the public perception cost of any battery issue is nuclear, as anything Apple is a headline. iPhones have strict shutdown temperatures for both cold and heat. (which make them useless in many outdoor work environments)

Surely without throttling it never draws more than 1A, that's actually enough to cause significant sag like the 0.3V example?
