Actually, draining a battery to 1% all the time is a bad idea and will shorten the batteries life. That isn't Apple speak i don't think, its any Lithum battery. I usually charge mine from 20% thereabouts.

Other times 10% or 8% at minimum
 
Why do people on here with iPhone 4S and a battery that’s 50% degraded still have full speed?

Looks like this wasn’t an issue before the iPhone 6, and all previous iPhones also used batteries.
Simple, newer the phone, the more powerful the processor and the higher peak power draw it can consume when running at 100%. Older slower phones won’t max out the battery the same way these newer high end ones would

Are you still using your 6S?
I always replaced my old model when the next one came out and never experienced these problems myself either...until this year when i kept my 7 Plus and the issues started to show.

No and I can’t remember what OS version I left off on. But this is only affecting phones with older degraded batteries. Not every single phone. It’s not like when you upgrade to iOS 11 on an iPhone 7, it automatically slows down. My girlfriend had a 6s until we recently got her an X and it was running iOS 11 since the betas just fine. It’s already been stated that it only shows during benchmark apps and wouldn’t show during normal use. I think this is a little overblown.

I don't know who wrote this MacRumors article but I'm bothered by the author's statements of supposed fact when, in reality, the "facts" aren't fully known at this time. MacRumors should strive to remain more impartial when reporting Apple related news.

Facts are clear to those who own an iPhone 6 and experience the slowness as their battery degrades. I have posted about this multiple times but now we have an answer. It takes 6-10 seconds to open an app on my old iPhone 6 and now my wife has the same issue. Even native apps are taking the same amount to open. There are thousands who have said the same thing on this forum. Not sure what other facts would we need. I am very disappointed in Apple and their practices. I actually bought a 8 plus because I thought my 6 was end of life. Their software made me believe this. Just wasted a lot of money when the 6 could have worked easily. I took it to the store and was told they don’t change the battery unless it’s below 80% and mine was 83. So Apple won with me buying a more expensive phone.

The lawsuit seemingly misrepresents Apple's original statement and suggests the plaintiffs and their lawyers do not understand Apple's explanation for how iPhone power management features work and why they were implemented
The plaintiffs must be forum members...

While I usually agree that not everything is always as big as we make it out to seem

There are a few questions that are still not answered from Apple that make this seem bigger

Why did Apple not speak of this until evidence unequivocally showed what they were doing?

Why was this in since 10.2.1 without it ever appearing in a patch note?

Why has Apple lied about throttling performance as recent as a few weeks ago when they’ve been doing this since 10.2.1? And only admitted to it after being called out?


That’s questionable behaviour. Even if it’s as minor a thing as you believe, the way Apple handled it is pretty bad

It did say performance updates in that patch
 
Err people’s phones are being slowed down when the battery degrades. In most of the world there is a two year warranty period, so if say after 18 months, they put a warning out saying change your battery, it would be at Apple’s cost not the consumers. Furthermore, if it ever came to pass that there was a known design flaw, in most European countries, consumers can make claims for up to 6 years irrespective of warranty status. Apple knew this and tried to make their phone “limp” over the warranty line or limp into the “upgrade” line.

In America, it’s only a one year warranty. What Apple did was fix an issue with older degraded batteries to allow the phone to continue to operate. Seems like you’re just making broad assumptions based on a number of users with a bad battery.

The A8 processor core in the iPhone 6 and SE, even though clocked only slightly faster than the A7 processor cores in the iPhone 5s, actually has between 50% more and 2X higher performance. That big difference in performance could cause quite a difference in power requirements (both peak and sustained). My guess is that Apple enables a turbo-boost mode in their newer A chips that only gets near the max with fresh new batteries on a cool day.

Unfortunately we don't know for sure the exact details of the cause, however I refuse to believe more advanced tech results in such unreliability that within 1-2 years of normal battery use the CPU is severely throttled, something is off hardware wise.
 
One possible settlement: all iPhones older than two years old (and can still run 64-bit mode, which means only iPhone 5S and newer models) gets a low-cost Apple-certified battery replacement. Also, iOS will be upgraded to detect these "new" batteries and run the phone at full speed.
 
You do realize, that people on here were denied battery replacements, because their battery was still above 80% health on the diagnostics even though they were throttled, right?

And yes, I would complain if my transmission stopped working after just 100.000 miles.

BTW: why are so many people on here always resorting to car analogies?

I suspect that much could come back to bite Apple. Slowing devices and still refusing customers battery service to fix the problem does not look good. I'm not sure how they allowed this much to happen, but I'm sure they will be putting it right ASAP by fixing diagnostics.
 
That's a false assumption, presumably made by a non-software engineer. Maintaining a deprecated code base is not always trivial especially when adding features as an OS level.

If anything, Apple should've been more transparent on the risks of updating to newer iOS. They seem to enjoy touting the positives.

I have been in software for 20 years and it’s always about money to maintain old code base. When you say trivial it’s about putting your best developers to maintain that code and you always want your best on developing the newest features.
 
it is throttled all the time when battery is "unhealthy enough". My 6s was running 911 Mhz all the time, after I replaced battery it went back up to where it should have been 1848 Mhz. It is consistent throttling. My friends phone was always at 600 Mhz before his battery was replaced. I'll take what I've seen with my own eyes over what any tech website states.

How do you know it was consistent? So they fixed the issue with older bad batteries (not all iPhones) and it’s a bad thing? The other option is to have them replace the battery.
 
I'm a long time Apple fan, and I love Apple but they had this coming and deserve it. Regardless of the reason, they've designed (or allowed to be within accepted tolerances) phones with batteries and CPUs with such tight voltage tolerances that Apple feels the need to implement extremely aggressive CPU (& GPU) throttling to keep the phone from shutting down. Imagine if you're Macbook Pro suddenly ran at half the rated clock speed or less after two years of use, I don't know of anyone who'd consider that acceptable.

For those of you defending Apple, here's my situation, I have an almost two year old iPhone 6S that often throttles down to:
1.8Ghz (base clock) @ 100% plugged in
1.5Ghz @ <90% battery life
1.2Ghz @ <80% battery life
911Mhz (Low Power mode clock) @ <50% battery life
~400Mhz @ <10-20% battery life.

FYI, the Geekbench scores reflect the decreased level of performance.

My battery according to Apple is at around 81% (coconut battery often reports 64-82%, so it may actually be worse) health (and thus just above the threshold for repair). While I have AppleCare Plus through early January and especially with the latest revelations believe I should (at the least) be able to get the battery replaced, this level of throttling for a battery that is supposedly not failing is totally unacceptable. If the CPU's voltage tolerance (for shutdown) is actually this tight, I'd consider that a design flaw. If it's not and Apple's throttling regime is just overly aggressive, that's just not ok. Phone CPU's are designed to burst (race to sleep), and if they can't burst that's going to erase any supposed "savings" of running at a lower clock speed.

Anyway, I'm hoping Apple's motivated to make better, more transparent decisions in the future.
 
Good. This could all be avoided if apple instead put in higher quality battery cells (apple watch's battery life is 1000 cycles), or if they make it easier to replace the batteries.


The iPhone carries the same 1000 cycle rating. They're not going to make batteries user serviceable ever. They need to rectify this situation but it's not about the quality of cells at all.
 
This isn’t consistent throttling. It’s only throttled at certain peaks. Even MacRumors/TechCrunch states..

“iPhones were hitting peaks of processor power that the battery was unable to power and the phones were shutting off. Apple then added power management to all iPhones at the time that would 'smooth out' those peaks by either capping the power available from the battery or by spreading power requests over several cycles.

"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.”

This doesn’t seem like nearly the same thing and they are making adjustments to phones as far back as 2013 last longer if there battery degrades past their supported battery life (500 cycles).

I don’t get the issue.

Ok, fair enough. I'll tweak the analogy: Toyota throttling my car so the engine speed is capped at 3000 RPM, limiting my peak acceleration.
 
Many other reasons such as?
The previous apps you just used filling up memory. Backgound apps. Stuck audio players. Stuck location apps. Stuck OS processes. Weak cellular tower signals. Weak WiFi access point signal. Lots of push email or notifications, big iMessages. Near full storage.

If I suspect some slowdown, I delete a few unused bloatware apps, check to see if some background, privacy or notification settings I don't need got enabled, clear Safari cache, recharge my iPhone to 100%, put it in Airplane mode, and reboot it. That usually fixes most sudden slow-down problems. If I turn off Airplane mode and the battery starts draining faster overnight, then I know a cell tower in my area is weak or too far.
 
Apple's intention is more than just acting like helping customers it's pretty dubious in my opinion. One obvious reason is to get away from liability of fixing someone's iPhone especially if they bought the Apple Care or any kind of extended warranty. All these years I act like there's nothing wrong with my phone not knowing that my battery is already in bad shape. Well if my phone will last all day or almost close to the end of the day then I assume no problem and Apple will just act like it's nothing wrong with it anyway. I heard people I know that Apple will just refuse to fix their phone despite them willing to pay for battery replacement. Another reason naturally we just assume that our iPhones is just slowing down then a lot of people fall on this. Apple makes us believes that's exactly the case therefore we need to upgrade. This is ridiculous and need to be stopped and make Apple held liable for their action. As if this company is losing money every freakin year and they done this on iPhone they've done this on iPads and iPods and MacBooks. No doubt!
 
I'm actually surprised these guys filed a lawsuit if their Apple users..... They didn't actually want to replace their batteries sooner? I suppose someone has to start it off huh

What makes this seem bigger is willfully ignoring the details. I'm not sure what lie you're talking about, but it probably has something to do with intentionally slowing older phones. They aren't, or at least this isn't evidence that they are.

Well mine and all of my friends did get slower. And i have a 7+ which worked perfectly on ios 10. I ended up charging my phone twice a day with iOS 11. Having the latest device gives you the best experience, until the next one comes out.

In my opinion, any of you complaining about Apple (re: your older phones) have no case. Once you agreed to the terms and conditions and installed the software, you gave up your right to complain about future actions like this.

Read the iOS 10 agreement.

People certainly haven't given up the right to complain. Even it was in the terms and conditions, that doesn't necessarily make it legally enforceable.

There's no way I can see Apple losing a lawsuit of this nature anyway, but it does potentially keep the story in the news for longer and that is damaging.
