With the iOS 12.1 update, Apple’s processor throttling comes to the iPhone 8/Plus and X

With the iOS 12.1 update, Apple’s processor throttling comes to the iPhone 8/Plus and X : Today’s lithium batteries are rated for a certain amount of charge cycles before they start degrading in terms of capacity or ability to provide peak current. This simple fact led to a real #batterygate scandal when Apple acknowledged that iPhones with aged or weaker batteries will take a hit in peak performance, in order to preserve their internals better.

Chipsets and other hardware are becoming ever more powerful and demanding, especially Apple’s AX line of processors, resulting in going over the fence when trying to extract stronger current from a weaker battery. At that time, older iPhones employed shutdown procedures to safeguard the electronics in certain extreme scenarios.

Apple tried to remedy the situation with the iOS 10.2.1 update, smoothing out the peak battery demands by dispersing them over several quick cycles. That meant throttling the processor’s power, and resulted in 80% fewer iPhone 6 shutdowns, Apple reported at the time, but it also made older iPhones feel comparatively slow. The thing is, however, that Apple kept this “performance management” system in the next iOS updates, too, so once the battery in your iPhone 7 aged enough, it became a bit slower and less responsive unless you cracked it open and changed the power bank with a brand new one at Apple’s expense.

 

When it comes to newer handsets, however, Apple’s support pages on the matter said that the “iPhone 8 and later use a more advanced hardware and software design… As a result, the impacts of performance management may be less noticeable…” The writeup, however, did include the ominous disclaimer that “over time, the rechargeable batteries in all iPhone models will diminish in their capacity and peak performance.” Now that the iPhone 8, 8 Plus and X are more than a year old, eagle-eyed reporters noticed that Apple has changed the support section’s wording as follows:
As a reminder, Apple’s iPhone throttling resulted in a huge community backlash and several lawsuits, forcing Tim Cook to out a letter of apology and Apple to commence its popular $29 battery replacement program in an attempt to regain the trust of users. Apple’s decision to lower the price of iPhone battery replacements to $29 (from $79; 63% discount), is now about to go into reverse, it seems.

With the launch of the new iPhone XS, XS Max and XR, Apple updated a lot of the terms for trade-ins, insurance, and, yes, the battery replacement tags. Starting January 1, 2019, eligible phones from the iPhone 6 and up, will no longer be able to take advantage of the $29 battery replacement deal.

The price tag will go to $49 for older iPhones, while the new gear from the iPhone X and up, will be charged $69 for a battery swap out of warranty. That’s still lower than the $79 tag Apple charged before #BatteryGate, and your XS or XR are unlikely to need the service in the foreseeable future anyway.

With the iOS 12.1 update, however, Apple’s “performance management” aka processor throttling has apparently wiggled its way into the 2017 crop of iPhones as well, for better or worse. Granted, their battery cycle counts are not even halfway through, and the more frugal chipsets as well as the smoother iOS 12 should make the tradeoff between slowdowns or shutdowns unnecessary, but we’ll keep an eye for any evidence to the contrary.
