I call bullshit. Reading the cached version, this is poorly disguised marketing lies for a third battery replacement service.
The test scenario was not described, this is only one sample which could have been selected and the source is not credible.
After 12 months of heavy daily usage on my 6s, I'm seeing 87% battery capacity left as an example after over 312 cycles. I am also seeing the same benchmark as the day I got it.
Yeah, I'm sort of getting the same whiff of bullshit. My dev iPhone shows 611 cycles and 86% capacity, with the same GeekBench scores around 1500/2600.
I know that's just one data point, but I'm super-sceptical given all of the misinformation that's been floating around about this topic.
My 6s plus is almost 2 years old and the battery life app is showing 76%.
Have not benchmarked it but it was only slow for a week or two after upgrading to iOS 11 and seems fine now. Did not notice slowdowns when using iOS 10 (which was when throttling was introduced)
My almost 3 year old iPhone 6 Plus shows the same scores as the the brand new one in that article, it even is a bit faster.
All i did recently was to reset the OS because it felt very sluggish on iOS 11 and after the reset it got a lot better.
if "everything" is slow on your iPhone, it’s probably not this issue related to older batteries. A full backup and restore is a pain in the ass, but it’s worth trying. There are clearly some bugs in iOS 11 that triggered such problems in far too many devices.
Ever since iOS 11 came out I had experienced a significant performance issue on my iPhone 6S. Animations and transitions were slow, app loading was noticeably and unbearably slower than iOS 10 and my battery was draining faster. Many rumours swirled that others were experiencing this but not all. […]
Then several weeks ago a Reddit conversation started spreading online that presented possible evidence Apple was reducing the performance of their iOS and possibly laptops when the battery life was sufficiently degraded. That day I decided to test the theory by getting my battery replaced at the Apple Store.
[…] After I confirmed with her that I was not using it that heavily and the battery setting statistics also didn’t show an application using a large percentage of the battery she suggested a rogue system process that somehow persisted through upgrades and restarts.
She also let me know that my battery was at 83% health and that Apple won’t even do a replacement unless it’s below 80%.
So I went home and immediately did a local backup, wipe and restore. And voila! Performance issues were gone.
There are various apps on the App Store. The data is available in a public API. I won’t recommend any particulat App because I don’t trust any of them.
I know that this article states a well-known fact at this point, but I can't overlook that it is on the homepage of a company that sells battery replacement services for iPhones.
EDIT: Also note that Apple as of today is offering battery replacement services themselves at $29. [1]
I took mine iPhone 6 in last night, was told about the $29 program, and asked if I wanted to wait. I said to go ahead and when I picked it up today I was only charged the $29.
So, just replace my battery every few months? That's OK? NO.
I'm losing respect for Apples mobile hardware line. So what if their SoC is amazing, if it is downclocked every month. Review benchmarks are dishonest if not taking this into account.
I made it up, I've seen no mention of a release. However that doesn't mean there won't be. The program isn't slated to start until late January so we'll have to wait and see.
Honestly I'd be surprised if there weren't some sort of indemnification as it's so common practice with everything today.
I agree and I'm not sure why you're being down voted for this remark. Apple should have been upfront about the issue from the start, with a solution that didn't involve third parties to fix from the beginning.
Apple has always relied on third parties to make their platforms viable and useful to consumers. The relationship is symbiotic, not destructive. Apple should be encouraging stronger cooperation between it and these third parties.
At $29 is is unlikely that Apple is making a profit on battery replacements. The third-party kits cost close to that much, and the labor makes up the difference.
They did invent a workaround to them that impacts other features without informing users though.
I'd also query the batteries more directly anyway though - if throttling is needed this aggressively, that _may_ indicate they aren't really up to the task (e.g. they don't have enough capacity to allow for the natural dip without it being an issue / Apple are claiming battery life figures that are basically unattainable in the real world, and propping them up by slowing the device).
Everyone defending Apple's behavior is missing the point completely. Yes, it's a reasonable way to manage degrading battery life and related electronic issues.
What's NOT reasonable is Apple CONCEALING this behavior. This led people to believe that they needed a new $1000 phone, instead of a $79 battery replacement.
My phone gives me a warning notification if performance might be getting degraded because the storage is getting full, and provides suggested actions to delete stuff stored locally.
Something about replacing the battery would have been perfectly reasonable for Apple to have suggested similarly, since we know the hardware can detect poor battery performance. Of course, we know why they didn't do this; it would cut into sales of new models.
Yeah, this is definitely not a normal thing then. It's certainly not a standard Apple feature to start warning people that they're running out of disk space when there's so much free.
I personally don’t think that those two things are causally related.
And that’s not with the ‘benefit of the doubt’, either. If you’ve run out of disk/swap space, then it doesn’t matter how much iCloud storage you have, your Mac will still be slow.
My four year old laptop (Mac) gives me a battery health warning.
I doubt the PM, UI, or otherwise responsible person made the decision to include this warning in MacOS as a way to dissuade me from purchasing a new laptop, just as I doubt that the responsible person intentionally omitted the feature from iOS (when the performance/battery feature was introduced in 10.2.1).
> Of course, we know why they didn't do this; it would cut into sales of new models.
We don't _know_. Many people have suspicions.
> I am certain there is too much certainty in the world

With the phone under warranty the new battery would be Apple's problem. This is about a defective product and fraud to cover it up, for reasons of cost.
That’s exactly the reason for the slowdown though. Phone shutting off = new battery under warranty. Phone silently slowed down = increase in new iPhone sales.
I’ve been on the fence about this whole battery gate deal. After all, I own some AAPL shares. But what you just said kind of hits the point. Having dealt with Apple’s support over various times in the past, every single encounter I’m crossing my fingers they would continue their generous ways and cover the issue — which they should. But by engineering an intentionally vague symptom of a real underlying problem, it gives their support staff some leeway to interpret each case and whether the customer gets the coverage (eg. Do they buy a lot of Apple products or have AppleCare on a lot of existing products owned?)
When I used to get Apple Care, the fine print said that if the battery capacity fell to 50% or below, within the warranty period (2 yrs) they will replace the battery (swap phones).
This worked for me twice.
Ironically, I stopped getting it because the batteries seemed to get better and better every year.
Modern smartphones seem to be a step backwards across the board in this regard compared to laptops. Pretty much all laptops have been able to do this across all OSes for well over a decade, probably closer to two. Smartphones almost universally hide battery health information from the user, even though they presumably have some way to monitor it.
More importantly, why have they designed their phones to exhaust their batteries so quickly? Either their processors are overspeced or their batteries are underspeced. This puts an asterisk next to all the benchmark numbers Apple loves to tout so much.
They traded function for form. Smaller batteries to make the phone slimmer mean less tolerances for charging and discharging (depth of discharge), causing short battery life (for the inverse, see Tesla; big batteries means less need to max charge or discharge, which means battery packs that last for a decade).
It's funny how nowadays (for a few iterations, actually) Apple's phones have bottom of the barrel battery life, even facing severe degradation in a few months, yet the reputation from 4S and earlier lives on. I know many people who still believe that Android phones suffer from faster discharges.
And it's also very important to consider the context: Apple is a company which earns the bulk of their revenue through new hardware sales. As opposed to their other issues (e.g. AntennaGate), concealing the performance degradation directly drove new sales and profits. It's significantly harder to give them the benefit of doubt when taking into consideration their hardware-sales focused business and the fact that they're actively fighting against right to repair legislation.
+1000. None of the Apple fanboys are willing to think in this direction. They are cozy and comfortable in their bubble. Apple did something here that is not trustworthy.
Apple didn't hide it. It was in changelog of some iOS version. They just didn't make it a big deal. Honestly I don't think that this is a big deal. Today's iPhone is absurdly powerful. This speed is not needed for average user, so he won't notice this downgrade.
It's a pretty hollow defense, because users are clearly not reading changelogs, and a reasonable person would obviously understand that a consumer's response to a poorly performing phone is conclude that it's time to buy a new one.
And my understanding is that there is no explicit mention in the changelog, just an opaque mention of new power management feature. But again, no one reads changelogs and the folks at Apple know that.
I bought a new iPhone every 2 or 3 years because of the slowdowns. I would have paid 29 euros for a new battery had I known that it would restore performance. Shit like this makes me hate the iPhone X I’m typing this on. I was thinking of getting an Apple watch but I will not buy it because I don’t trust them anymore. They better restore trust or it will cost them a lot of sales in the long run. Making phones with replacable batteries would be a good start.
It looks like the CPU-slowdown-for-old-battery thing was only introduced about a year ago. So you can probably blame your X purchase on this (especially if you came from a 6 or maybe 6S -- a 7 should not have been significantly affected unless there is a bigger battery issue with it), but before then your older phone were probably "naturally" slow.
At this point how do we know Apple doesn’t make intentional decisions that slowdown older phones? Maybe CPU benchmarking tools where given all CPU power in the past and they forgot to implement it now, just like the GPU manufacturers were caught cheating.
To be clear, unless I have completely misunderstood this issue, this throttling feature was only introduced in iOS 10.2.1 – which was released less than a year ago.
If you have been experiencing slowdowns prior to that, then it seems like it would be a different issue?
Apple kept silent everytime the slowdowns were discussed. They could have come forward many years ago, but it’s only after they took it a step too far with the iPhone 6 and people had definate proof that they came forward. I gave my iPhone 6 away out of frustration with it’s performance, while it was easily worth a hundred or more dollars, even taking the battery costs into account. I’m really, really pissed right now.
Replaceable batteries are going to be the revolutionary new feature on the iPhone 8. It's going to be insanely great and you're going to wonder why everyone doesn't do this with their phones.
With the technological advances of recent years they might even be able to do it on MacBooks too.
I always wonder if slowing down the phone is a good solution. By slowing down the CPU the CPU needs less energy. But at the same time the user has to wait much longer in order to finish what he was trying to do. Thus the screen is on for a longer period of time. Isn't the screen one of the main energy consumers in an iPhone?
Launching apps on my iPhone 6 (which needs a new battery) takes for ages (even when compared to my older but less used iPhone 5S). I can't imagine that the extended "screen lit"-time does not have a big impact as well.
Also: I am one of the few users who would be totally fine with the iPhone shutting down at 20% or so (if I have the full performance as I used to) because my iPhone is rarely going near 20%. At work I can charge. At home I can charge. When I am on the go I usually am not using the phone that much... However playing hearthstone when I am in bed, loading the phone, everything takes much longer as well which makes playing games less fun...
The issue is not specifically about battery life, but about the ability of the battery to provide a stable voltage under load. The voltage of the cells sags more under high current draw as the battery ages; reducing the current draw by throttling the maximum SoC frequency seems to be intended to avoid the problem where the voltage dips to a level that causes the SoC to shut down suddenly.
Edit: I see others have addressed this in the very long time it took me to express myself!
As I understand it, as batteries degrade it's not only the total capacity that drops, but also the voltage the battery can deliver and the CPU requires a certain voltage to run at a higher frequency.
So, a fully charged, yet degraded battery, may have the overall energy needed to run a CPU at normal Mhz, but may not be able to deliver that energy fast enough.
As I understand it, the main issue is that the power output of the batter decreases as it degrades, not just its total capacity. Apple claims that the throttling is needed in order to prevent the processor from automatically shutting off because it can't draw as much power as it requires -- not just to prevent the battery from draining faster.
How did they generate this data? The screenshots say that all of the benchmarks were made within an hour of each other, and out in order of the charge cycles. Are they swapping out batteries?
- Apple makes phones that have batteries normal owners can't replace.
- When the battery degrades the phone's performance degrades.
- Users either pay for a new phone or were paying $80 for new batteries.
- Apple admits the ruse, lowers the replacement cost to $30, basically admitting that $50 was profit.
- Turns out another company already did replacements for $30 and was probably making money on it. So Apple's still likely making money on it.
- Users get upset but line up around the block to buy whatever Apple puts out anyways --
sight unseen.
We get the behavior we incentivize. In this case we get planned obsolescence and shakedowns for repair. Until consumers vote with their wallets, all this kvetching doesn't mean shit.
But this whole controversy reminds me of a few years ago. When people were very happy with their iPhones (including some of my friends), because they manifested and maintained "battery life" that their friends' Android phones did not.
Maybe Apple shouldn't have hidden what they're doing. Maybe it's arguably a legitimate trade secret (I'd hardly be in favor of "patenting" the functionality).
Anyway, now Apple's "shit" for how they manage battery degradation. A couple of years ago, or whenever, before all this upset: They were "the shit" with respect to battery durability -- as perceived by users in their charge lifetimes. At least, among some of my friends. And some press, IIRC. And whatever.
Apple's not magic. Their batteries degrade, too. On the other hand, the vertical integration and efficiencies they are engineering into their newer chipsets? Pretty amazing.
P.S. I'm no Apple Fanboy. Just recalling how perspectives change.
People think technology is magic. When they find out it's not magic, and hard decisions were made around tradeoffs that they had no input in, they doubt the reasoning behind those decisions.
IMHO throttling the phones was the correct decision for the vast majority of their users. Warning about degraded battery performance would be preferable, but when do you do this? If this is an adaptive behavior, it may be throttling to 99% early on in the phone's life — so when do you alert? At 95% two months in? At 80% performance a year in? Apple can make another decision here, but people will still find ways to argue about the specifics.
I think you're making a mistake of treating users of X as a homogenous group. Some users were not happy with how the performance and the battery degraded. Some were happy with the power usage over time. Some were happy to point out how they're better than the users of Y.
All of that is still the case. What changed is that "I think my iPhone is getting slower, but I'm going to replace it with a new one anyway" is not interesting news, but "it's been proven why it's getting slower, now I feel ripped off because I didn't actually need to upgrade the whole phone, just the battery" is interesting.
Regarding the first, Apple has -- since its renaissance -- consistently had a limited number of products. Limited product lines. They themselves lump users together, to some degree; and many argue for this advantage: High quality products that "just work", and don't make me choose between fifty-odd variations.
Regarding the latter, I generally agree. I'd much rather know what's going on and have the choice of spending circa $100 (supposedly formerly $80, now $30 for a year), to replace the battery. (And a separate pox on "thin" making all these batteries unremovable; but I guess that's my personal preference.)
Maybe Apple knowingly benefited from uninformed user upgrading. How much of that was battery/throttling, and how much of that was Apple users wanting to have the latest and greatest -- for functionality and performance, or just for status? We may never know.
But, as I mentioned, the perceived charge lifetime and durability of same, were -- as far as I saw -- major marketing/selling points of iPhones. And I recall myself grumbling about how my Android phones' charge lifetimes were decreasing, mere months into the devices lives.
I don't know whether this could have been patented (like stupid rounded-corners patents and so many other things). But, it wasn't. Was Apple obligated to reveal this "secret sauce"? I don't know.
For most people, the implementation seemed to work out fine. Friends with 3 and 4 year old iPhones, while many Android users could barely make it to 2 years (for multiple factors, not just charge lifetime -- e.g. timely and ongoing updates, anyone?).
I wish there was a phone that wasn't so wholly owned by big corporations. As opposed to its users. But it seems to be the nature of our world.
Geekbench CPU scores from the release iPhone 7 running iOS 10 show scores of around 3400/5500. My 14 month old iPhone 7 running 11.2 reports around 3500/5900.
So no slow down on this model. Battery capacity it as 87%.
I have an iPhone 6 that’s about a year and a half old, and although I experience frequent & noticeable slowdowns while using it, and although my battery life has noticeably decreased since I started using it, the Geekbench score for the phone is higher than the average iPhone 6. It makes me wonder what’s going on.
It's funny that most everyone I know with 6 or 6s has problems (slow, bad battery) and everyone I know (including mysel) with 7 has no problems what-so-ever. Maybe 6 was just a bad product?
I have a 6 plus. I broke the screen a few months ago, so they replaced it with a brand new 6 plus (hence new battery). It is very slow in much the same way that many other people describe -- it will just pause for a long time (a minute or more) in some weird stuck state. The old phone that I broke had the same problem. I have the minimum apps installed, and background refresh disabled. My wife and mother both have 6 pluses, which exhibit the same weird long pause slowdown behavior. After trial and error, the best hack to get around it is: (1) when it happens, immediately turn the phone off and on with the upper right power button, then (2) immediately after the phone turns back on, close all running or suspended apps. If you don't do (1), then you're just completely stuck for a long time. I've had this problem before and after iOS 11, and with my new and old phones.
I have had a 6 Plus for 3 years, my girlfriend has a 6 as well but none of us have the issues you describe. Yes it got quite slow with iOS 11, but it's just a bit laggy at times, no long pauses that require a reboot.
I don't think this is true beyond benchmarks. They stress test the CPU and that's when the throttling hits the hardest. It's throttling peaks in CPU usage, and a benchmark is all peak.
So this sounds like a worst case scenario. Actual use can be completely different.
Not defending Apple though. This complete lack of communication over an obviously controversial choice is amateurish. So much of this could have been easily avoided by clearly mentioning it in a Beta release, along with of course implmenting an on/off switch!
Do bear in mind the issue in question is voltage spikes (which cause unexpected shutdown), that's what Apple is trying to prevent. Most of the time there'll be no performance impact, it would just lower how far the phone can boost clock speed when it needs it, I'm guessing? So it would affect the peak (and therefore mean) performance, but not the mode or median, I think?
Modern CPUs will pretty much always try to boost as long as they have the thermal and power headroom to do so (see race to sleep). Talking about mean, median, and 'mode' of performance is going to be tricky because it'll be heavily dependent on how the tests are being run. Things like, is there enough time to rebuild thermal headroom between iterations, or does a single iteration ever actually run enough to exhaust its thermal headroom will effect the results of multiple runs.
So returning to the base point, any reduction in boost frequency in -normal- usage (seperate from benchmarking) will cause (machine) measureable (but maybe not perceived) performance loss because everything is built around trying to crank out work as quickly as possible for as short of a time as possible.
Not for a company getting multiple iPhones of various age every day in for repair. If they can do a check on some percentage of their customers, they're likely to get tens/hundreds of data points a day and be able to graph an average age-vs-slowdown relation.
If they started after the original forum post, they should have a pretty good idea already.
This is making an interesting case for using an external battery case to keep the phone at 100% more often and reduce charge cycles.
I wonder if the comparable battery performance gaps perceived by for many Android users will be seen as closer than we thought - of Android devices secretly dialed down its devices would they have much better battery life.
Interesting for me is that my iPhone 4 is much faster than my iPhone 5S. And the battery lasts much longer on my 4.
I think what Apple changed these days is that the latest version of iOS works both on 5+, while I remember my iPhone 4 was stuck with old version and I was never able to upgrade it.
I have an android phone - the nexus 5 and it's a total shitbag right now. It seems like it's slowed down massively. I can't imagine this is only apple.
There's an issue with earlier nexus phones and nand degradation. Lack of TRIM really killed them over time unfortunately. Running some write/read benchmark app and comparing the results against published numbers (like http://www.androidpolice.com/2014/11/20/anandtech-posts-side... ) could (dis-)prove that's the case.
Nor the operating conditions (temperature in particular), which as Apple mentioned rightly in their press release can have quite a substantial impact on how quickly capacity degrades.
Would the type of case used contribute to premature wear? Thinking Otterbox rugged type cases causing the battery to retain excessive heat while charging.
Does it even bother anyone at Apple that their company has a problem with ethics?
It would seem as an engineer, if your boss told you to write code that intentionally slowed a user's device down (for ANY reason), wouldn't the proper response be "Will do, but how do we inform the user so they can avoid it?"
What frustrates me most is Apple won't learn a lesson from this, they just merely "got caught" this time.
Well, all phones intentionally slow themselves down (throttle) when they get too hot; peak CPU performance can only be maintained for a certain amount of time until it cools back down. I don't think any mobile OS directly exposes this to the user. Lowering peak performance in the long term is different, but I suspect they didn't see it as all that different.
I agree. To me, this is indicative of a deeper cultural problem. It sometimes happens if engineers don't speak up and get involved with the product. This causes a culture of engineers turning into executers, where they just execute the feature or the bugfix, without even _trying_ to think of the end user, or possible repercussions.
Not that the engineers are the ones at fault, it just seems that a culture change is needed to get everyone to care more about the customer.
> a culture change is needed to get everyone to care more about the customer
I think they care a great deal, but arrogance (as so often) leads them to lack judgement. Their ‘care’ has become a patrician “we know what’s best” (cf. not permitting MacBook Pro customers to have real keyboards because wanky Ikeabot Jony Ive finds them messy).
At some level of the company, but we don't know that the _engineers_ didn't respond like that. If you query it and get a response like "The UI team is taking care of that", there's not a whole lot you can do.
Forced obsolescence.. so many other things could have been done. A battery saver option could let users pick their performance options, but no, just get a new iPhone for $800...
the problem is not performance vs power usage, the problem is the cpu faults and the device reboots because they fucked up completely on engineering safe voltage margin into the thing
all cpu faults if undervolted. tipically the more the clock speed, the higher the voltage needed so that transistor keep working correctly.
on a mobile device battery degradation is normal, with that comes less viable battery life but also a lower voltage
when you put togheter the two things you just need to plan accordingly. that's what was the whole kerfuffle: they didn't
it doesn't help that they use short lived batteries in iphones (go check it, ipads are rated twice the cycles) but the whole issue comes from bad engineering of the cpu/gpu or whatever they put into that doesn't work with the degrading battery output the device should have been built to cope with
There's absolutely no good reason why iPhone batteries are not easily user-replaceable. All the reasons usually given are weak excuses for an essentially consumer-hostile hardware design.
If the battery was easily replaceable, then I doubt there would be much outrage about this issue. But with the iPhone, device and battery are fused together and are thus seen as a single unit.
I don't think those things are mutually exclusive though. My Lumia 950 has a user-replaceable battery, and I've dropped it multiple times. The back has never come off as a result.
The test scenario was not described, this is only one sample which could have been selected and the source is not credible.
After 12 months of heavy daily usage on my 6s, I'm seeing 87% battery capacity left as an example after over 312 cycles. I am also seeing the same benchmark as the day I got it.
