Battery recall or class action lawsuit, your choice Apple.

Or they could just remove this crap from iOS 11...

This is nothing but a cheap move to make more money, the usual from Apple really that we’ve been seeing over the last couple of years. I was checking out the Apple Watch straps the other day, £150 for a bog standard Apple leather strap.... yeah..... I bet that cost all of £4 TOTAL cost, oh wait maybe it had to have years of research and development in a buckle?
I’m sure it’s not made in a Chinese sweat shop factory for peanuts...

So these moves don’t surprise me. Because if your battery doesn’t last you go and get another, if your phone is running really slow guess what you naturally go out and buy.. not a battery!

Update on that article.

Update: Developer Guilherme Rambo has discovered the software system, powerd (short for power daemon), that Apple put in place in iOS 10.2.1. powerd controls CPU/GPU speed and power. It also responds to thermal pressure and helps iPhones from catching fire.

That said, correlation doesn’t necessarily imply causation.
 



Primate Labs founder John Poole has plotted the kernel density of Geekbench 4 scores for iPhone 6s models running iOS 10.2, iOS 10.2.1, and iOS 11.2, visualizing an apparent link between lower performance and degraded battery health.

The charts show that on iOS 10.2, the vast majority of iPhone 6s devices benchmarked similarly in performance. However, Poole explains that the distribution of iPhone 6s scores for iOS 10.2.1 appears multimodal, with one large peak around the average and several smaller peaks around lower scores.

In other words, after iOS 10.2.1 was released last January, the performance of a percentage of iPhone 6s devices began to suffer.

In a statement, Apple said it made improvements in iOS 10.2.1 to reduce occurrences of unexpected iPhone shutdowns that a small number of users were experiencing. The shutdowns were reportedly caused by uneven power delivery from older batteries, which could cause an emergency shutdown of the devices.

While at least one report suggested that Apple tweaked its power management system in iPhone 6s devices, the company never disclosed what specific improvements it made to reduce the unexpected shutdowns.

A recent Reddit discussion, however, has reignited speculation that Apple is intentionally slowing down older iPhones to maximize power efficiency and stability when battery capacity has degraded, and reduce voltage-related shutdowns, and the Geekbench charts and Poole himself lend credit to that theory being true.

"The difference between iOS 10.2 and 10.2.1 is too abrupt to be just a function of battery condition," he said. "I believe ... that Apple introduced a change to limit performance when battery condition decreases past a certain point."

The charts show that the number of iPhone 6s devices with lower Geekbench scores was even more pronounced on iOS 11.2, which is likely because the software update is around one year newer, which means that the battery capacity of many iPhone 6s devices has likely continued to deplete as expected.

Interestingly, even the iPhone 7 may be starting to be affected. While the distribution of Geekbench scores for the device on iOS 10.2, iOS 10.2.1, and iOS 11.1.2 appear identical, the results change with iOS 11.2 and start to resemble the iPhone 6s' degraded performance starting on iOS 10.2.1.

What this all means is that Apple may be intentionally slowing down older iPhones to maximize power efficiency and stability when battery capacity has degraded, as speculated, seemingly without publicly acknowledging so.

It's important to remember that all lithium-ion batteries naturally lose some of their ability to hold a charge over the course of a few years. Given the iPhone 6s was released in September 2015, the device has been available long enough that some users should consider replacing their battery regardless.

Apple charges an out-of-warranty fee of $79 to replace the battery of all eligible iPhone models in the United States. iPhone 6s users can contact AppleCare or schedule a Genius Bar appointment at a local Apple Store using the Apple Support app.

Apple did not immediately respond to our request for comment about the Geekbench findings. We'll update this article if we hear back.

Some people here really need to buy some aluminum hats and take place underneath the stairs, conspiracy everywhere! So Apple is trying to control the user experience on a model that was once high tech.... no news at all, the whole philosophy of Apple is to control the user experience...

In Android you have buttons and sliders to slow down your device (next to the system itself), in iOS this is obviously done for you automatically. You might find this inappropriate, but it is what it is. Go to your local shop and get your battery replaced, and you are back on top....

The issue is that the customer does not know that replacing their battery will improve performance.

That is on top of the fact that apple states that they will replace your battery if it drops under 80% , so while you say they are controlling user experience, they are also controlling $$$$ for replaced battery units.

It would be nice if Apple informed people about potentially replacing the battery to solve performance issues, but being “nice” here wouldn’t be in their best interest.

On the other hand there's this:
People would then moan that Apple are using system popups to try and extract money from people.

Yep as I said earlier, terrible battery life would be the biggest factor in persuading people to buy a new iPhone. Most normal people simply do not recognise stutter and lag.
 
Battery technology is the achilles heel of mobile devices. Not really seen any breakthrough progress in this area.
No it isn't.

The high current draw of antennas is the issue. Why else would an ipod last a week on a charge, but the iphone would last less than a day.

If your phone needs a new battery, apple is saving you from a potentially dangerous situation by making your phone last longer... If you need a new battery, get one. Quit whining.

There is only one 'real' wear item in the iphone if you take care of it; the battery. My iphone 6 is approaching four years old and it's still very usable. It's on it's first battery. I'm a little thrilled by the idea that if I have the battery changed, my phone might speed up.

I'm not whining just expressing my view. Components are more efficient than ever but every day battery usage has changed very little over the years. Still say battery technology hasn't progressed enough and I'm confident others agree.
 
My 6s has 199 cycle battery and 90% wear ! Cpu maximum clock is 911 mhz, and 600 mhz just after 70% ! All this, doesn't really matter for me, but what it does, is the below 10% of battery, cpu fall down to 100 mhz ! And make the phone unusable, you can't even tap the passcode and phone calls are like parasites where you can't even make your voice heard ! This unaccaptable
I think this proves that some batteries are worse than others.
The biggest problem is that if you want Apple to change your battery and PAY for the battery replacement, they will refuse because your battery has more than 80% of its original capacity.

Given Apple’s issues of late with obvious, glaring problems in macOS and iOS - My confidence in them correctly coding this sort of tricky software-based management system is pretty darn low.
Yes. Looks like I picked a good time to jump ship to Linux. System76 wants your money. :p

Update on that article.



That said, correlation doesn’t necessarily imply causation.

Powerd has been around forever in iOS. It might have learnt new tricks in 10.2.1 but it’s not a new process.

Rambo doesn’t say powerd is new either just that it has the capability to lower processor speed. This is interesting but isn’t this exactly what you’d expect of a power management feature? Particularly when you have low power mode etc already baked into the system.

The 9to5 article makes it sound like powerd is a nefarious process added into iOS at 10.2.1 which is wrong.

The 2g iphone cell was 412 Wh/L. The cell in the 8 plus is just shy of 700 Wh/L. That's quite a jump without even considering the improvements in power density.

What aspects of the battery do you want to see improved exactly?

I own a couple of external batteries for charging my iPhone for those days when I need to use my phone excessively.

Now, it appears iOS is taking over, throttling performance.

Making calls and listening to music are fine but my key workflows (why I stump up money for an expensive smartphone) are rendered useless (ie. I can't take snap with the camera as startup times are +15 seconds and an unresponsive keyboard is forcing me back to pen and paper).

We get to control the style of battery use on our MacBooks (ie. performance over availability). Please give us control over this in iOS Apple.
 
The focus of many of the discussion are on the 6S, and I offered a possible solution. And it's not a "small fraction." It's practically the whole early batches of the 6S, and thus Apple is still running the program since 2016.

Meanwhile, what have YOU contributed?
LMAO
I have contributed like a lot. I’ve followed it closely since Dec 11.
That you are saying this is mainly about 6s is too superficial, as the iPhone 6 and 6 plus are severely affected.
It’s not just about the 6s, all affected models are of the same rooted cause.

How long in real world usage do each last?
 
I just did a Geekbench test on my iphone 6 and the score is way down. On the other hand the battery is not too bad...

What's your score? My 6 is scoring 1555 (SC) 2685 (MC)
[doublepost=1513686978][/doublepost]

Depends on who is using it, doesn't it? Additionally, this would tell you nothing about the state of battery development as so many other factors play into the current draw.
 
Want a really easy solution which has no downsides for customers?
Tell customers to get a new battery!!!
It is not a tough choice or decision in 1 billion years.
Oh there is one downside for Apple though: replacing more batteries for older devices instead of selling more new “better” iPhones.
[doublepost=1513665808][/doublepost]

I don’t have to try anything.
I am telling you my personal experience.
I had lived with a throttled to 600 MHz iPhone 6 Plus for over nine months before I was finally forced to upgrade to an iPhone X, which, if you don’t know, cost a lot of money that I might’ve saved if I had known they had intentionally crippled my 6 Plus.
You feel me, bro?
The problem is especially prominent when you are switching between different Apps. And don’t tell me nobody should use several apps simultaneously. You must have hear of something called multitasking.
Think about it. Why should I make that up? What is it for me to defame Apple?
I love Apple products. Everything I used has an Apple logo on it. But this shady behavior is intolerable.

Stop ranting. Don’t be afraid of what you might discover. Pretend you are a scientist and do a simple test.

Put your in low power mode; now it is running at half speed. Operate your phone as usual. Scroll through 50 open tabs in Safari. See how amazingly smooth your phone is, even at 1/2 speed?

As I said, if you were having problems with words not appearing for 30 seconds, your problems were much different than simply a down clocked processor.

If you’re unwilling to investigate the effects of clock speed on a good battery, your credibility in this thread will suffer.

Please report back your findings and let us know how your phone works clocked at half speed.
 
My 20 months old 6s is good as new. I’ve never ever experienced CPU throttling on any iPhone I had.

Lol, thinness is the real issue here, no room for adequately specced battery for the power draw of the components.
You actually get it. Lipos that are designed for higher current loads tend to be thicker and heavier for the same amount of capacity and voltage. Apple bases their their main criteria on whether a battery needs replacement just on total battery capacity - which does wear out over time. The problem is that either these batteries are underspecced, or they wear out too fast with another criteria - Internal Resistance. As some lipos wear, their IR goes up much faster than others. This causes significant voltage drops when you're trying to draw too much amperage. Apple's trick software purposely limits the current draw of the CPU to prevent these shutdowns. The problem is that for some people, their batteries are showing this behavior before the batteries drop below Apple's stupid "magical" 80% capacity limitation that they require in order to get the batteries replaced without an argument. It's also cheaper for them as it keeps them out of warranty costs if the iphone is still under applecare..
