Geekbench Results Visualize Possible Link Between iPhone Slowdowns and Degraded Batteries (geekbench.com)
Earlier this month a post on social media which suggested that Apple might be deliberately downgrading performance on iPhone models with degraded battery was widely circulated. Benchmark Primate Labs' Geekbench has looked into the matter and is corroborating the claims. From a report: 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.
Let's look at this from a usability perspective. If you make a device with a non-replaceable battery and you want the device to have good battery life for as long as possible, what would you do? I would decrease the processor speed/energy demands as the battery gets older and the capacity diminishes, thus artificially making the battery appear to retain its original charge time as long as possible.
Batteries don't just have less of a charge when they get older, their peak draw also diminishes. If, when you are using an older battery you need more than the battery can supply, the phone reboots. So Apple is slowing down the CPU on older iPhones so they do not go over the max battery draw available on older batteries.
It is preferable to have a slower iPhone than it is to have it rebooting. If the slowdown is an issue, replace the battery for $75 and the performance will be back to normal. As for those who complain "I want a removable battery", well I much prefer having the water resistance that has saved my phone a few times than a removable battery that I only need after 3 years.

Very interesting story and I have a data point to add: I bought my iPhone 6 new in 2014 and as of about two months ago the battery (which was at more than 750 cycles - Apple rates it for about 500) was getting really flakey. The reported capacity of the battery started varying between 45% of its rating and 85% with random power offs becoming common below 10%. So last weekend I finally bit the bullet and put a new battery in - fiddly but doable in about 30 mins. I then reset the phone and left it to fully charge overnight.
Since changing the battery the iPhone has been subjectively faster to launch apps and display information. So this report that Apple may have something in iOS that compensates for a failing battery doesnâ(TM)t seem implausible.
Though I would have thought that a better thing (or perhaps as well as) would be if Apple gave the user an alert once 500 cycles exceeded advising them that the battery was wearing out and linking them to the official Apple page for getting it changed.

To tell us all this is a great this apple is doing. Crippling their phones.
The retard runs on diet coke and Fox News, that's going to take years off his battery - in prison.
The link is the code apple uses to throttle the CPU when the battery get old.
The newest upgrade for ipad prevents it from recognizing external batteries, so if you run out of juice you can only recharge through an adaptor or usb port.
Look, I'm a "techie" person but I'm not statistician. What the fuck do these graphs even show? One axis is "Density" which is seemingly the kernel density... of something? The other axis is "Geekbench 4 Score" and I have no fucking idea what that even is.
Seriously, if you are trying to explain something to me using charts, you're going to have to make it clear what in the flying fuck you are charting.
Anons need not reply. Questions end with a question mark.
Just because it's a good design doesn't mean it's okay to deliberately deceiver your customers. How about admitting that their non-replaceable batteries have failed on schedule, instead of silently crippling the device.
I am shocked to see comments that defend what's going on - and to be precise, what is going on is not having:
INFORMED the user
and/or
PUT A SETTING to let the user be in charge
Instead, they hoped we wouldn't notice and simply slide it under the rug, "oh I guess old stuff runs slower" so we throw it away and buy the new versions.
Very sad. I'm a 6s user hit by this and my feeling, after many many years of iPhone love, is to start looking at Android.
