For the conspiracy theorists, instead of thinking that they needed an excuse for low iPhone 8/X sales, have you thought that what they really need is to get rid of a huge inventory of batteries?

:D :p

Think again...lithium ion batteries operate the same way for voltage during discharge regardless of brand.

Nominal voltage or higher is supplied for 80% of discharge. At 20% discharge, voltage will start dropping rapidly below nominal. Since nominal voltage is what the phones and apps are designed to work within, lower than nominal can cause problems in relation to what the CPU is trying to do. That's going to happen with any brand of phone. A simple Google search will bring up plenty of examples of Android phones shutting down this way too...which is why other OEMs only denied that they had a throttling feature to prevent shutdown, not that their phones couldn't shutdown for the same reason.

http://appleinsider.com/articles/18...k-and-how-apple-manages-performance-over-time

So why aren't iPhone 4S, 5, and 5S affected?

Why is Apple designing their phones so that even the slightest degradation in battery health requires throttling?

They're throttling phones with batteries that Apple themselves report as "Healthy" and would not replace.

Of course, the bigger issue is they didn't tell anyone and let them believe (even told them directly in some cases) that their phones were just slow from new software.

So why do people keep bringing up battery chemistry? ;)
 
Me. I keep my phones as long as they have good performance. Conversely, I don't if they don't. If Apple is, in fact, going to lose sales this whole situation points back to intent.

I upgraded my 6 to a 6s six months ago because the former became a pig. I don't need the newest phone and I got a great deal.

Lots of people may think like you, but I'm not alone here either.
I'm with you, I tend to keep my phone for as long as it works, but I know plenty of people who buy the latest and greatest iPhone/iPad/MBP as soon as they come out.

A few months back I did have to replace my battery in my iPhone6, in Nov I bought a new iPhone 7+ because I was going to give my 6 to my daughter. This whole battery nonsense is seriously making me reconsider future iPhone purchases, I just don't feel like switching...
 
Apple phones were shutting down because the battery could not provide the voltage the chipset needed.
That is a defect..

No, it's a limitation of lithium ion technology. Standard lithium ion batteries will always have a much greater risk of voltage problems in these three scenarios, regardless of phone brand:

1. Battery is EOL. At that point, voltage discharge becomes less predictable and will rapidly decline.

2. Battery has a low charge. Voltage will begin to rapidly drop below nominal at 20%.

3. Battery is cold. Voltage can drop rapidly below nominal.

Again, all three of those scenarios can happen with an Android phone battery, and those are the scenarios Apple specifically talked about in regards to when the throttling feature might need to kick in to prevent shutdown. Go back and look at the statements other companies made. They didn't deny that the same voltage problems applied. Only that they didn't throttle their phones to prevent shutdown...which isn't really doing the customer any favors. Apple added the feature after customers complained about the shutdowns.
 
Her three year old phone is slow?

Wow.
Yeah. Guess it needs a new battery. As long as the phone or other solid state device has not been physically damaged, there should be no performance degradation other than power related issues with the hardware over a 3-5 year period. That leaves software updates as the main potential culprit in slowing down the devices. Support for phones earlier than the 6/6+ have two issues in the fading of continued support: lack of recently manufactured battery replacements, and withdrawal of software support for 32-bit platforms. It may be that later iOS updates cause performance problems with features designed for newer hardware (like 3D touch and faceid) which aren't featured on older phones, but that becomes a problem with the updates' design, not the phone hardware. I bought a new 6S+ about 6 months ago as a replacement for my 6+, as the price was a bargain a year after its introduction and it retained the phone jack. Because of the bargain price, it was an attractive alternative to paying $90 to replace the old battery in the 6+. Realistically, I really didn't notice much performance difference from the 6+ (other than new battery), and it featured 3D touch and some new camera features (live photos). Never ran iOS 11 on the 6+, so perhaps that would have exacerbated things.

Under inventory control and operations genius Tim Cook? Nah.

It reminds me of people who think iPad (2017) was launched because Apple was sitting on a pile of old iPad Air parts. iPad (2017) doesn't have any chassis cutouts that match iPad Air.

You are being disingenuous to the discussion.....
all 3 of your points above are normal.......

But why does an iPhone shutdown at say 50% battery left because the CPU could not handle the voltage coming from the battery?
They didn't deny that the same voltage problems applied. Only that they didn't throttle their phones to prevent shutdown...
So you admit that iphones will shutdown when other phones won't! Thanks!
Only iPhones shutdown when the CPU cannot get enough voltage from the battery. This can happen when it has 80% or 50% doesn't matter how much battery life the battery has. The phone was shutting down.

Glad you can finally admit Apple was shutting down iphones when other phone makers were not.....

Then as others have said..... This only affected the new thinner iPhone 6 and above models using the thinner batteries.
So why aren't iPhone 4S, 5, and 5S affected?

I guess. Can't fault people for wanting to make their devices last, especially if they don't have the funds for the newest phones or the features of the latest phones don't appeal to them. Some people can get one device/phone/etc, and be content with that for long periods of time and not have to worry about shelling out more cash. Hell, if it wasn't for me wanting to try out the Pixel XL, I would still have my Nexus 6, and if it wasn't for me wanting the full Android experience that wasn't bogged down by bloatware, I would still have my Galaxy S5.

I understand it from a company standpoint of wanting to keep a consistent cashflow, sure, however, if folks wanna keep their older devices, then they shouldn't be penalized for that.

Isn’t that in fact the primary reason? New iOS on old phone crushes it to the point of being frustrating to use so buy new phone. That’s the pattern of most people I know. Not all. But most.

i doubt the battery related downgrade is nearly as impactful as iOS upgrades vs the model. To say that the battery replacement would thwart a new purchase implies that the degradation is equivalent to at least a whole generation difference. That sounds ridiculous.
That software updates, that are designed primarily to accommodate features on newer phones, often noticeably slow down older hardware I think is an update problem. The only real updates needed by older phones (and computers and tablets) are security patches. Unfortunately, that granularity is generally not offered as an update option. To get needed security updates, older hardware becomes stressed by having to run larger and more demanding (of the hardware) executable code in the OS. One-size-fits-all becomes a detriment to older hardware with each passing year. That would be less of a issue if the hardware was relatively inexpensive to replace, but as we all know, that is not the case with iPhones and Macs.
 
How did you keep it anchored on 9 so long?

I have automatic downloads and every setting turned off that I think is relevant, but my phone still downloads iOS 11 in the background and prompts me again and again. I don't keep my phone on the charger at night either, only during the day.

Install the Apple TV Profile on the iPhone which stops the nagware from Apple to upgrade iOS beautifully

Im still using 10.3.3 and wont ever upgrade on my 6+. I wish I kept iOS 9 now...

How do you know they're not? They use lithium ion batteries too, so all three scenarios that Apple has talked about would still apply. My own guess is that Apple is putting the focus on phone models that constitute the majority of their install base worldwide. 5s was only 12% of that in April of 2017. 6/6s combined was over 50%.

Those models are old and slow enough that consumers are replacing them naturally.

On the other hand, iPhone 6 and newer owners need a gentle nudge.

No, you're intentionally misrepresenting what was said.

What the other OEM's did say: "we don't have throttling".
What the other OEM's didn't say: "we don't have shutdowns".

Lack of throttling does not prevent shutdowns due to voltage issues that are standard to lithium ion technology.

Except new iOS features aren't usually backported to older devices so there's no reason for slowdown.
 
SOrry if already been mentioned (I haven't reviewed all 10 pages), but I think it will affect iOS12 uptake too. The trust is gone. Apple is slowing our phones. The long suspicions have been proved true (even if not in the way anticpated) and I am sure many will not upgrade./

For me, oddly, I think it's had the opposite affect. I had decided a while ago not to upgrade my 6S to iOS12. But I think now Apple may have a point to prove and will keep phones super responsive for longer. My 6S (with a new battery) is great at the moment. But I certainly won't be an early adopter anymore. Been stung too many times.

Apple stated that the software feature they added doesn't cover the 5s or earlier, nor does the battery replacement program. That doesn't mean it can't have voltage issues in the three scenarios Apple specified. It's just a very small part of the installed base now.

Seems reasonable. But I don't think they will say anything to indicate they made a change.

Just like the iPhone 6+ bending. Nearly everyone claimed that the accusation of them bending easily was false and yet Apple tweaked the design of the 6S+ to strengthen the area highlighted as the weak point in the 6. Apple didn't officially acknowledge the change.
 
I was ready to upgrade my 5s but now I don't want to if Apple is putting cr@p batteries in. Sigh, maybe better batteries in 2018 phones?
A question I have regarding battery replacements in 3+ year old iPhones - how long do new batteries for older models continue to be manufactured? If you were to buy a "new" battery for your 5s, would that battery truly be new? My guess is that you are getting a battery that may have been sitting on a shelf for a couple of years or more, in which case it is likely to be in a degraded state. Sure would be nice if battery sizes didn't have to vary with every new phone model, but were somehow standardized - much like good old lead acid 12 volt car batteries. Those batteries have had fairly standard form factors for decades, even with significant capacity improvement. The same goes for alkaline batteries, which have had standard sizes for decades (C, AA, AAA, N, etc.). Consequently, you can still start up a 20 year old car or a 10 year old flashlight with a battery manufactured today.
