"iPhone 8, iPhone 8 Plus, and iPhone X models include hardware updates that allow a more advanced performance management system that more precisely allows iOS to anticipate and avoid an unexpected shutdown."

Does this mean the 7 and prior have a 'dumb' method of determining when to throttle, like cycle count instead of precise battery age, while the 8 forward rely on precise shutdown conditions?

This is a question that should be answered too, batteries have a lot of luck and variation in care associated with them, one mans 500 cycle shutdown-prone battery may be another womans 500 cycle 90% fine battery.

I made a similar comment when my SE was in a steady state of 50% throttling.  My theory is that for the "older" phones (I.e. not iPhone 8 or X), Apple’s throttling algorithm is more simplistic, looking mainly at things like battery age and cycle count. I had not been experiencing any random shutdowns or other behavior prior, and the throttling became noticeable only when I upgraded to iOS 11. 

So essentially, in order to be cautious and to CYA, Apple’s initial throttling procedure was very aggressive and ended up blanketing batteries that may have otherwise been perfectly fine. 

Since replacing my battery two weeks ago, performance is consistently at 100% speed and runs like butter.

I agree. Which (with such good intent on Apple’s side) is why they should have been transparent about the fact they were throttling speed.
The moment someone has to discover a correlation between battery health and phone speed, is the moment you are in legal trouble.

I'm curious.

When Apple said:

iOS 10.2.1 includes bug fixes and improves the security of your iPhone or iPad.

It also improves power management during peak workloads to avoid unexpected shutdowns on iPhone.

What did folk think they meant by 'power management'?

What should they have said?

My assumption would be they would do things similarly to how the implemented low-power mode and cut out background tasks, stop push notifications, dim the display or other things that would prioritize power to the app I was currently working on.  Cutting performance by up to 50% of my active application would have been at the bottom of the list of suspected actions.

What they should have said was "Identified an issue where insufficient battery output causes unexpected shutdowns on iPhone.  Peak performance may be reduced by up to 50% to avoid unexpected shutdowns."

I might add that during observations of my SE prior to a battery replacement, I was seeing drops of performance of up to 66% (from 1850MHz to 600MHz clock).  I have Geekbench results showing this drop.

That being said, 50% (911MHz) was the typical clock that my 1.5 year old phone would comfortably sit at for the majority of the  day. 

New battery and the clocks remain steady at 1850ish MHz. Rock solid. Phone is a joy to use again.

That "our implementation will be a blanket solution for any battery we deem to be "old", and we will quietly throttle back performance of your iPhone 6, 6s, or SE to iPhone 5 level performance without you being the wiser to it." 😜

I've downloaded the "Battery Health" app which shows anywhere from 14-20% battery wear.. Irrespective of what level of charge it's at. 

Agreed that the battery shouldn't be an issue at this point.  There hasn't been any noticeable decrease in battery life nor random crashes or shutdowns.  I've owned three previous iPhones that, over the lifespan of use, have never experienced as dramatic a decrease in performance as my current SE. 

Hmm, interesting. Thanks. I guess I got one of the good ones. I've still got it on my calendar to get a replacement in Nov/Dec before the program expires (no matter the state of the battery).

Just a quick update for now... I bit the bullet and decided to go ahead with the battery replacement instead of waiting for Apple's "spring" software update on the throttling debacle.

Suffice it to say that my SE feels like a brand new phone again!!! 😁. It runs buttery smooth and is a joy to use, just as I remember it when I first picked it up a year and a half ago. The benchmarks and clockspeed utilities corroborate with this perception, as my phone shows a constant 1800ish MHz clockspeed no matter the battery charge level. In fact, as the new battery was only at about 10% capacity when I retrieved it from the tech, I was shocked to see that even at that low charge it was still running full speed (battery saver feature turned off).  A quick Geekbench test also supported my finding. 

To all the naysayers, it wasn't the old hardware (CPU) that couldn't keep up with iOS 11... It was Apple's throttling implementation that made my phone feel like it was running an A6 or A7 chip, and not the A9 as advertised. I'm just glad that Apple "allowed" me to replace the battery on this occasion after my previous experience (before their PR campaign kicked into high gear.)😒

I took some before and after screen grabs from the battery and CPU utilities and will look into sharing them when I get home. 

Other than that, I'm psyched! Feels so good to use my phone now!

"  ... including the ability to toggle the power management feature for iPhone models with aging batteries."  The toggle should say 'Sensible mode' and 'Idiot mode.'

False. But kudos for the pretentious name calling. 

The insistence that the throttlling is only for old batteries is inaccurate. Unless you consider a one year old battery with no prior instances of performance issues to be fair game for a 50-66% CPU downclock. 

False, the throttling is far from 55% let alone 66%!!! Mine was less than 12% before the battery replacement. 30% when on high usage activities.

And IT IS idiotic choosing constant random resets and app crashes over a small decrease in performance.

If it bothers you so much just change the old depleted battery for cheap with Apple.

Very worth it!

Thanks for letting me know your experiences.  Please be aware that your experiences do not speak for everyone else. You are lucky that your unannounced throttling is/was less than what I and others have been saddled with.

My 1 year old SE downclocks anywhere from 1500MHz to 600MHz. This is a very perceptible slowdown, with many apps becoming a stuttery chore to use. Miraculously, at full battery charge, the CPU comes back to near or full speed and everything works like a charm again. 

Never experienced random shutdowns prior to the ios update. 

I suspect that while Apple may have had good intentions with the feature, the implementation is too aggressive or perhaps too much of a blanket solution.  Such that, even  healthy batteries are given the downclock treatment when a more elegant solution would have excepted them. 

Informing the consumer of this tweak and offering a choice would have been the right thing to do. I applaud the fact seekers who unearthed this issue and forced Apple's hand to come forward. 

And when your phone crashes, forcing you to reinstall you and others that did it will likely whne about it... But hey, you had the choice so hopefully it will be a quiet whine.

Sigh.... Yes. I'm sure that this silent throttling was done in the best interest of customers, and nothing more.  Even though Apple told me that my battery was fine when I tried to replace it mid December.  I guess I'm the fool for not buying into the PR. 🙄
