Yes, my iPhone is slow like crap with the latest iOS 11. Apple better replace my battery at the next genius bar appointment or they might lose a loyal customer who has been with them forever!

All the best. Let me know if they do replace. I am going to try in Australia where I am on vacation and then back in India. I have written to Mr Tim as well on how this practice made me buy a new iPhone. I like to keep my phones for at least 3 years if not more but this time 21 months.

I still haven’t seen a single Apple apologist acknowledge the fact better battery tech exists ...

Yes, slightly battery battery tech exists, but as Samsung proved, rushing such stuff to market can have disasterious consequences. You don’t want your phone to light your next airline flight on fire.
 
I’m an app developer. Benchmarks are very different from normal apps. The iPhone display runs at 60 Hz. So does the GPU pipeline. Most games and smoothly animating apps update once per frame (every 16.67 mS), and have some margin left over (a few milliseconds) so they don’t drop frames on older models of device in the worst case. Benchmarks usually leave no margin, so the processors don’t have time to cool down between display frames. That idle cool down time between frames of a normal app allows the power management controller time to boost back up for the next peak load.

Most apps other than games and animated eye candy idle even longer between updates, waiting on the network, or for storage data, or the GPS, etc.

Don’t trust those benchmark apps to measure true clock frequency or normal app performance. There are too many variables not under their control.

Happy new year mate ! I'm jumping offine in a sec to enjoy the fireworks
 
Sorry I’m missing something - I don’t understand why battery replacement will speed up a phone ?? So do the updates ruin the battery ???

If your battery is below 80% total capacity, replacing it can make a difference because that's EOL for the battery. Performance can get much more erratic below 80%. Prior to that, it's just going to run down faster because of capacity decline. Keep in mind though that performance can potentially be effected at very low charge levels with a non-EOL battery due to the steep voltage drop off once you get to 20% charge or less. That's why Apple gives you the low battery warning at 20%. More demanding CPU tasks below 20% might cause problems due to the voltage requirements possibly getting too high for the battery to support. That's the issue that Apple was addressing with the throttling feature. It's a way to keep the phone functioning in a voltage situation that might otherwise cause a auto shutdown of the phone.
 
Like responding to customer complaints about auto shutdowns with a new software feature that helps reduce the possibility of that happening (in addition to providing free battery replacements for the 6S serial numbers that were having most of the shutdown problems). So shady...
they throttled everyone's phones for almost 1 year without telling anyone, they didn't bother to mention that a fresh battery could help with older phones and encouraged upgrades instead, they made in-store battery replacements an expensive hassle by charging $80 and requiring that the battery fail their diagnostic even if the customer was willing to pay full $$... all for the good of the customer

Wish we were all smart as you to not update. Just curious, why didn't you update? And do you update your apps as well and/or does all the apps still work?
I'm not a heavy app user, I have about 12 apps I open and use on a daily basis and all work fine. I keep them all updated.

I have a huge iTunes music library most of my own CDs which I created all the album artwork. I really like the look of the music app in iOS 9 and the color overlay of the albums. I didn't like that they took that look away and then added more white and weird/huge child like fonts. It just looked like a step backwards.

I've also been a firm believer that the best iOS is the one that comes pre installed on your phone. I've heard others say the same thing.

In other words, just the sequence of events supports Apple's story for why the software fix for auto shutdown was added. Remember, the iPhone 6 and 6S were huge sellers for Apple. They weren't struggling to get people to buy phones at that time. Those were a runaway success with new Plus size screens added into the mix. Does it really make much sense to say that they had a motive to slow down people's phones for sales?


The first slowdown algorithm was "featured" in iOS 10.2.1 which was released January 23, 2017, after the iphone 7 was released in November of 2016. So your argument that it would make no sales sense for apple to cripple 6 and 6s phones doesn't make sense, if (as was clearly the case), Apple was in the business of selling iphone 7s at the time the (6/6s) crippling was implemented.

Furthermore, Apple didn't start crippling the iphone 7 until they were in the business of selling the iphone 8. The iphone 8 having been released in in September of 17, and the iphone 7 being crippled in iOS 11.2 released in December 2, 2017.
 
First of all, Apple does say what they consider the EOL for the battery to be: 80% capacity, which is pretty standard for lithium ion batteries of any type. Does every customer know that? No, but you can't claim it's something Apple is hiding from them. The information on that is available. People in these threads constantly quote capacity numbers they're getting from from apps on their phones etc. as well.

As for the limited range, yes, it is factually true that the majority of people complaining about auto shutdowns after the 6S launch had 6S phones in that range. That doesn't mean those were the only people who could experience one, but a defective battery is going to make it much, much more likely. Thus the unusual amount of complaints that launched the investigation by Apple and ultimately the free battery replacement + software tweak.



The software feature Apple added monitors for big peaks/valleys in power draw. Those are what can potentially cause auto shutdown when voltage is too low. Geekbench benchmarking itself can trigger the throttling, so a lot of people that think "I ran Geekbench and the numbers were too low" aren't really seeing an accurate picture of what iOS is actually doing for apps that don't intentionally load the CPU to it's maximum.

https://techcrunch.com/2017/12/20/a...ones-with-older-batteries-are-running-slower/

From the article: Remember, benchmarks, which are artificial tests of a system’s performance levels, will look like peaks and valleys to the system, which will then trigger this effect. In other words, you’re always going to be triggering this when you run a benchmark, but you definitely will not always trigger this effect when you’re using your iPhone like normal.

non benchmarks apps report a cap on CPU spend. TechCrunch is making a statement it cannot back up. Do they know the CPU runs are full speed when not benchmarking? What proof do they have?
 
But they're not saying that. They haven't said "our phones will never auto shutdown unless the battery is at EOL" because that wouldn't be true. Look at the lithium ion discharge chart I already posted...any lithium ion battery that hits the 20% charge mark is going to go into a steep decline for voltage available to the CPU. Could you trigger an auto shutdown by loading up the CPU when the battery is very low? Yes, you could.
i think you're confusing the 20% on that referenced plot, with what the iphone shows as the remaining battery charge (upper right battery icon) ... iOS power management manages what's shown for battery percentage, the OS will move that around relative to what's its power management calibrated during it's natural discharge throughout the day
 
Okay, so, it seems Apple is throttling our iPhone 6 even at 78% battery charge level!

Ok, I have some battery data that doesn't make logical sense and would be interesting to see if Apple has been pulling a fast one on its consumers. I just used CoconutBattery on my MacBook Pro to check all of my batteries on my iOS devices. From what I have read, Apple store employees can check your iOS battery health and determine if the battery needs to be replaced, but they will not tell the consumer the actual battery condition. I wonder what equipment/method is used to check the battery health?
Interestingly, I have an 2.5 year old iPhone 5S that registers 660 load cycles on the battery and still shows the battery health at 91.4% design capacity.
My 2 year old iPhone 6S that registers 560 load cycles on the battery and only shows the battery health at 73.5% design capacity. This is a big discrepancy. Especially since the 5S has 100 more load cycles than the 6S and almost 20% more battery life. What gives, Apple? Did Apple start using inferior batteries once they switched to the iPhone 6?
Did they build in obsolescence to get people to upgrade?

What about the iPad batteries? My iPad Pro 10.5 only has 70 cycles and is already down to 92.6% design capacity. Doesn't look good for battery longevity. Hopefully someone will check on the iPads............
Great research and I would like to know the answer to this as well. How does Apple defend these results?

i had an apple tech recently tell me that coconut battery doesn't display accurate life readings -- i asked because CB was showing 86% on my iphone 6, but apple tells me that the actual capacity was >90% and that it's fine -- what are we supposed to believe ?

And this mess up is going to cost Apple some of that money. Mistakes happen it’s part of life. It’s what you do when after that defines you. Especially after getting caught doing something shady.

no hiding it in a update. This hasn’t even started yet. This is gonna grow. Apple is in full blown damage control.
 
Before I got my iPhone 6s I had an iPhone 5 and just around the 2 yr mark my phone was shutting down at random but only when at 20% battery or less, if I opened the camera app at say 15% my phone would shut down with the symbol to plug it in leaving you stranded unless you have a outlet. I remember taking it into the Apple Store and they hooked it up to their diagnostic machine but wouldn't let me look at their screen. It threw a code that I needed a new battery so I had to fork out $80.00

Soon after Apple issued a recall on the iPhone 5 batteries as faulty so I called Apple Cust Serv and they asked me to email them my invoice showing I paid 80.00 at an Apple Store and in a few weeks they sent me a refund check for $80.00 in the mail.

It was such great Cust Serv and it made me so happy that it made me want to get the iPhone 6s about a year later.

No discount for iPad battery replacements? The one in my Air 2 doesn’t seem to last as long as it used to.
 
Did you ever check your serial number against the 6S batches that were known to have defective batteries? Apple had a replacement program for that.
[doublepost=1514750587][/doublepost]

Your question was: "what phone isn't able to operate regardless of charge".
The answer: depends on what you define as "operate". Turn on? Edit 4K video? Lots of different possibilities.

Yes - and at first I went to an Apple store (before Apple announced the “bad batch”) and when I explained my issue to the Apple genius, she literally looked at me with fright. As soon as I said it powered off at 80% battery and didn’t turn back on until connected, her eyes went large. THAT is when I knew, she knew, that internally they were being briefed on something.

Their advice was to wipe the device and try a fresh install. My battery passed their diagnostic test, displaying less than 20% wear (above the 80% threshold) and a replacement was denied. Of course she and Apple knew full well all along that a reinstall of ios would get me nowhere, but they made me waste my time doing that anyway...

A few months after that came the “6S” recall. The same battery, the same phone, they later went ahead and exchanged for me after I had to inconvenience myself and show up a second time once everything was “official”

Anyway - the problem extends to the 6, the 6+, the 7’s and 8’s and probably the X’s too.

If the phones weren’t defective, they would run at their full speed capabilities. There is no point in having an iPhone 8 which in theory with the latest chips should CRUSH the iPhone 5S. Yet Geek bench tests are showing that they’re basically being crippled to the same speed as a 6 year old device. That’s so shady and unacceptable. ;(

And this is exactly why when Apple makes a mistake, especially having to publicly by press release admit it, they need to go OVER and above to absolve it and learn from the mistake never to repeat it again. Integrity, in the eyes of life long customers has been shaken.

Your second sentence , you can apply to your first - we both don't know the numbers involved .
Not really... defects are going to be small numbers. The phone is too old to be any mass issue. The amount of people taking them in is always going to be significantly fewer on a 3 year old phone than a relatively new phone.
[doublepost=1514762570][/doublepost]
Apple doesn't care if you are happy or not. They know they will still buy their phones and Apple is a company. They couldn't care less how you feel, as long as they get your cash.
They go together. They know to get your money and keep getting it, you need to be happy.

It’s all just business and they do it better than any company in the world.

Cost of doing business, buddy. This will be relatively minor. They are in front of it now and controlling the situation. I believe they’ll turn it into a a positive with more retail foot traffic.
 
You must own some share of apple to have this view..
Zero shares in Apple (or any company for that matter). Not the investing sort.

I pay Apple for their product only!!!!!!! I don't pay for their opinions on what they THINK is best for me or how my phone works.. When I purchase the product all their opinions on how I should use that product END!!! That's what I purchased. And I'm pretty sure most posters feel the same..
Like it or not, it’s a package deal. You can’t have one without the other.

That to me is the Apple premium. You know how people like to say “why buy an iPhone when it’s twice the price of an android phone?” Well, I am essentially paying for Apple’s expertise in crafting a unique user experience in a way that that no one else can. That’s what justifies the Apple tax for me.

And that unique experience is derived from the integration of their hardware, software and services, including continued software updates which change the device based on what they believed is in the best interests of their users if need be.

Call it meddling if you will. But since I choose to embrace the Apple ecosystem, that means also trusting Apple to do the right thing for their users. Sometimes, they make the wrong call and screw things up, but I believe their hearts are in the right place and more often than not, they do by right and the end user is better off for it.

As I said earlier, it’s all one package deal.

If you don’t want software updates or want to be able to customise the device any way you wish, Android devices are that way. Though you will likely find that you are simply trading one set of issues for another.

Moments like these and I remember just how much cash Apple has on hand, and how tempting it would be to use said cash to pay for comments like these. Not that they would do anything like that of course, and not that your comment was paid for, but it makes one wonder.
I’m just not unreasonable. Companies can do the right thing and I think Apple stood up and did the right thing when they could have been a lot harder to deal with. I actually don’t think they are legally responsible for any wrongdoing but they are trying to keep happy customers.

Ultimately, they are driven by money, which is ok. They can’t appear like they don’t care or they are jerks, so they just made a business decision. Anything regarding their intentions is just speculation.

They did the "right thing" after they got caught sneaking in throttling algorithms in point updates to iOS that only effected previous generation phones; which at a minimum certainly caused some users to upgrade to new phones due to performance issues, instead of getting replacement batteries, because apple conveniently failed to disclose all of this to customers in a way that average consumers could reasonably understand. This is not an example of a company looking out for the best interests of their customers. That's fine, Apple is just another corporation, but stop the self rightious moral posturing from here forward, Apple!
