That link is about the relationship between the CPU and peak voltage...which very few people posting in this thread seem to have any knowledge of whatsoever.

It's an article for overclocking ....... for a desktop system, running a PSU ..... yes a CPU has a peak voltage... And one would be daft not to use a very good quality PSU for overclocking . This is just going to backfire on you cause going down that analogy apple used a poor PSU , and had to run the CPU under clocked. The lesson here, choose the right PSU for the system ;) if you are going to use desktops to support your argument . FYI , not all PSUs are equal, you need a very good one for Oc

I've spent years overclocking , don't mix OC with a system that fails to run at default settings. A system that fails to run at default setting is flawed , find the component causing the issue and replace it, do not under clock your system , that is daft.... why waste money on a CPU that cannot run at its rated speed
 
Geekbench triggers the throttling because it creates the large peaks/valleys in power draw that Apple's new software feature is monitoring the system to prevent. Apple specifically states that. The guy that wrote the article for TechCrunch shows why that's true. Note that he specifically says that Apple doesn't deny that Poole's charts are accurate because they're showing exactly what Apple wants to happen when the peaks/valleys are too high.

In other words, Poole's charts prove what Apple is saying, not what you're saying.

It doesn’t trigger the throttling. If that was the case, CPUdasher would indicate the 6s phone running at 1848 MHz (expected speed) with phone “idle”. I firmly believe the throttling is entirely based on battery health and is applied 24/7 until battery replaced.

I don’t trust what Apple says about peaks and valleys. After all they weren’t gonna tell us about this anyway until they were caught.

This issue was identified back in April in the official Apple forums and just now coming to light this past month.
 
Just FYI, My wife has 6 plus for nearly three years. Very extensively used mobile as business mobile never reported any slow down (touch wood....) No Issues so far. Battery seems to be doing good. Is this issue related to cold weather regions? I have kept on upgrading OS until latest! She is refusing to give up and opting out of mobile upgrades!

Out of warranty two years back and never bothered to take Apple Care type protection!!

We all have iPhone 6. When I checked the CPU Frequency yesterday at 50% battery charge level, the phone was throttled about 30%. But now when I checked it at 99% battery charge level, there was no throttling! So, it appears Apple slows down the device as battery charge level drops.

Our phone also has no issues other than waiting more than five seconds to open up some big apps like Facebook for the first time.

I have a 6s that never shuts down prematurely or in the cold. I have a friend with one where this always seems to happen. There are defective batteries out there and Apple's "power management" approach is catering to the lowest common denominator. Even at the lower price I need to change my battery too early to cater to accommodation of bad battery batches.

No, a lithium nominal voltage will stay the same overtime, it will drop only if the battery is at it's end of life.

Nominal = average, so the voltage does drop consistently over time. However, the drop is the biggest at the beginning and the end of the battery life...the majority of use will see very gradual change.
 
What about those of us who already had to replace the battery, I wonder if we can get compensated???
Depends how recent. Apple is usually good about giving refunds if you ask. Curious to see what you find when you ask.

Apple had a battery replacement program for the 6S within a specific serial number range due to a known issue with battery defects.

And the newer CPUs? Are they more fault-tolerant at default settings, or less? Will it be worth buying. Faster CPU if the battery ''fails' the CPU sooner?

Yeah, I shouldn't use nominal, your right.
But, still a lithium battery voltage won't change until it's almost dead.
Most batteries type's will deliver the voltage until near the end, whatever the chemistry, it's the current which drops overtime.

Fixed.

As you can see here voltage won't drop even after 600 hours of charging.

Have you battery checked and replaced when you are less than 50% charged?
 
Well Apple uses water damaged boards in refurb devices. How anyone trusts them anymore is beyond me.


Apple wouldn’t have done that, all they do is send the devices off to a company they have a contract with who then does the repair at a cost agreed with Apple, and a quality agreed with Apple so Apple would have said don’t bother with the underfill, use water damaged boards, we need to cut costs and make more profit... in all honesty they aren’t the only ones who do this, but I bet this is how most devices are when they are bought as replacement devices in the Apple store. I mean if you’re phone is broken, and Apple replace it for a charge to you, do they really use a new phone or a reconditioned one...

As successful as Apple is, they make some incredibly poor choices in favor of squeezing every last dollar of profit out of it's customers.
Apple has a history of first denying that a problem exists, then spinning it as something minor, then finally addressing the issue (although not always). Rather than owning up and correcting an issue, with a relatively small hit to the bottom line, they aren't ethical and customer driven enough to address the customer's concerns. These are not small dollar purchases for most consumers. Stand behind your product and stop being cheap. Premium products demand premium, solid gold level customer service and complete remedy to a faulty product.

My lagging 7 Plus is merely one year old, it deserves justice instead of a battery.

Sorry Apple but you’re too late. I’ve already had my battery replaced 1x and at one point purchased an Apple a Smart Battery Case.

I’d still be using the phone if it wasn’t slow again and the batteries dead. Let the class action suits continue.
 
The 5S could handle old batteries :) like all iPhones prior

Not really. I still have my 5S and it was experiencing the shutdown issue pretty badly, sometimes with as much as 40% battery power left. Per Apple, they didn't implement throttling on this model.

I ended up buying an iFixit DIY kit and replaced the battery myself. Shutdown problem solved.

What Apple wants to happen post 10.2.1. Before that it would be a shutdown.

The problem I have with this fix, is that I am not getting 100% of the performance I paid for. And when these shutdowns were happening to the 6S these batteries were barely over a year old. Apple Care and 2 year Warranties in the EU were in full effect for these devices.

Should a phone have to be throttled to prevent it from shutting itself down when its barely a year old or should it be replaced under warranty?

Those charts show that its already repeating itself with the iPhone 7. Which again is barely 1 year old.

Incorrect. It's always decreasing over time which is why "nominal" is used to describe voltage in lithium ion batteries. It's never really constant (kind of like nature itself). Like I said, the bigger drops are at the beginning and the end of the life cycle. Most use will fall into the "nominal" range though, so generally speaking what you're saying is accurate in terms of what the user would experience for performance.
 
Thats like what i said? At the end of the day its just stupid like let me spent 29€ on you if i want to spent 29€ and if i want to spent another 29€ a few weeks later let me spent another 29€

Sure - there are no environmental concerns letting every yokel on the street that feels like their phone is slow spend $29 to replace their battery, and definitely no concerns about these yokels creating a scarcity issue/delays for those with real battery problems.
