Except that it gets unbearably un-zippy. If battery life really gets so bad that Apple believes it will reflect poorly on their brand, then they could do in-store same day battery replacements. But that would cut into their profits wouldn't it.

You think they don't make money on $80 battery replacements?

Profit on the $80 is much less than profit on a $700+ new phone.

Most? Absolute nonsense. The Nexus 7 have a small issue that was resolved when Google added TRIM support for Android. That was years ago. I have a long history with almost every Android device. The device doesn't get slower, the battery life just gets terrible.

The 2012 Nexus 7 is an outlier because it has especially bad flash controller - by 2015 most of the devices were unusable due to degraded flash. TRIM helped very little. Other devices suffer from similar effects - not as bad, but most devices certanly lose quite a bit of I/O performance (especially writes) over time which makes OS run noticably slower.

Flash degradation literally only affects writes. Android has had TRIM since 2013. Writes in no universe make the OS run "noticeably slower" (or lead to "lag"), even if your claim was proven.

There are literally billions of Android devices. Benchmarking file system performance is trivial. Ergo, where are the benchmarks supporting your broad claims? This should be incredibly easy to demonstrate. We do know that it happened pre TRIM because people had factory new and after use benchmarks, and could show the decline.

Why does this correlate so well with iOS version increments? My iPhone 6 was faultless prior to the upgrade to iOS 11, and immediately after it battery life was greatly reduced and it now shuts down automatically when the battery hits 10%. Apparently I am now supposed to accept that the battery has degraded not gradually but all at once and on the same day as I upgraded iOS, and this is now being managed for my benef…

In the same boat with my iPhone 6 and also curious. Day-to-night degradation after iOS 11.

> This post is written as if it wasn't Apple that introduced the hard-glued battery. They made a consumable hard to replace As others have pointed out in this thread the batteries aren’t hard to replace; this is just not something you can do directly as a user. That probably makes sense; it’d be difficult to make a super-thin smartphone while at the same time provide an easy way to replace each part.

These are completely unfounded guesses. You have no basis upon which to determine whether it's "difficult."

> These are completely unfounded guesses. You have no basis upon which to determine whether it's "difficult."

Those are guesses, which is why I used "probably" and "it’d be". Glueing parts together takes less space so it makes sense they use that to make phones thinner. I’ve yet to find a single smartphone with the iPhone 7’s thickness and a replaceable battery. The Fair Phone has a replaceable battery, but it’s thicker than every iPhone since the 3GS from 8 years ago.

>For people familiar with electronics yes. Familiarity with electronics doesn't matter. We can't allow vendors to simply simply cover up what are normal behaviors from components given typical operating conditions.

Yeah we can, that's how vendors make products better than the sum of their components. Nobody wants a DVD player which throws up an error and stops playing if the disk is scratched, compared to retrying then skipping on a few frames. Nobody wants a streaming video which stops playing if there's temporary bandwidth problems instead of pixelating briefly and coming back. Nobody wants ECC memory or hard disk error corre…

With the exception of DVD and hard disk bad sector error correction, none of your examples are relevant because they are temporary conditions that are reversible. With persistent media failures there is an issue of data at stake, and replacement would cause data loss, so the next best action is to recover as much as possible. It's already in failure mode. In all of these cases graceful recovery is appropriate because there is no other alternative.

Apple does have an alternative. The battery issue is neither irreversible nor has any permanent ramifications to the remedy of just replacing the f-ing battery. In fact I have no problem with graceful degradation as a stopgap. Explicit Power Saving modes already do that.

But the issue at hand is completely orthogonal and has to do with why Apple refuses to, at the same time as undervolting, also signal to the user the one sane action to take, which is to obtain a battery replacement. By not signaling such and misdirecting (whether intentional or not), they are passive-aggressively telling the user to replace the entire phone. How else would a typical user interpret this situation? In what way could they know the appropriate action to take from observation? You think a company that prides itself on every meticulous detail of the UX just "missed" this?

I smell an antitrust ...

This has nothing to do with a monopoly, so antitrust law is totally not applicable here. You might be thinking "class action lawsuit", which someone might attempt. However, if Apple can show that this is actually a mechanism to provide maximum screen time for the life of the battery (as opposed to malicious planned obsolescence), the suit would likely fail.

I feel the same applies to Macbook as well. I've a Macbook Pro Retina 13 inch, early 2015 at a battery cycle count of 1001. From the last few weeks, the system is terribly slow. I randomly see the fan speed going berserk. :/

Dust-clogged fans and degraded thermal paste can also be a factor, particularly after 3 years.

I replace my iPhone battery with a cheap one off eBay every year or two when something else breaks. Battery life is pretty good, but the screen pops up now making the phone 0.5mm thicker. It's doing OK for a 5 year old phone, but my friends can't believe I paid $800 for an iPhone 5.

I don't understand. Why did you pay $800 for an iPhone 5?

Maybe the poster is talking about total sunk cost of phone and all of the batteries

That's what a 64GB iPhone 5 cost at the time.

If the screen is popping up, that condition might be trigerred by a swollen battery. My iPhone 5 also did that, after a while, it worsened so much that the screen colors became affected. I took it to an apple store, paid the fee and had them replace the battery. IMHO a swollen battery is a huge risk, and apple should have replaced my phone without charge. Anyways, be careful and if the battery is swollen, it's time f…

My first battery was definitely swollen, and this may be why the screen doesn't snap back into place.
