Group FaceTime and dozens of new emoji were parts of a bunch of new features that Apple introduced with iOS 12.1.
Unfortunately, there was a controversial new performance manager feature to the iPhone X, iPhone 8, iPhone 8 Plus.
Moreover, in the release notes for iOS 12.1 we can see that indeed the performance management feature was introduced.
However, why is this a bad thing?
The problem is that to protect devices with aging batteries the CPU throttling feature would deliberately slow the performance of the 2017 handsets.
Unfortunately, the same algorithm that reduces the performance of aging iPhones to supposedly protect its electrical components while preventing it from shutting down because of low battery performance is still present in 2018.
Another controversy is the statement of Apple that with hardware improvements on the next generation of iPhones CPU throttling was not necessary, especially on the X/8 range.
Not only that but internal memos show that iPhone 8 and later use a more advanced hardware and software design, which allows for more accurate estimation of both power capability and battery needs.
Apple Pays $5.7 Million Fine
Fortunately, there are good news, since you can disable the throttling performance by entering the battery health section and disabling the peak performance capability feature.
However, that option is only available if the back 3 in your iPhone 8 or iPhone X is not able to support the peak performance of the device processor.
This resulted in Apple having to pay €5 million ($5.7 million) fine for throttling older devices, in an antitrust case brought by the Autorità Garante della Concorrenza e del Mercato (AGCM).
It is currently unclear how big of an impact battery degradation will have in models that would release just over a year.
However, Apple said that the throttling issue goal was to deliver the best experience for customers, being the feature, not a bug.
This is what happens when lithium-ion batteries power your device, they eventually degrade.
Unfortunately, Apple is letting us choose to a certain extent whatever we want to throttle our phones rather keep them running at peak performance at the cost of battery life.
Moreover, if your phone needs a battery replacement, you can grab Apple’s current offer of “cheap” battery replacements until the end of 2018.
Many people accuse Apple of deliberately slowing down the older iPhones to force on users to upgrade to newer models.
As of iOS 11.3 users will have a battery help feature that gives control over the CPU throttling feature and informs them if the battery needs to be replaced.
