Apple Now Faces 26+ Lawsuits for 'Purposefully' or 'Secretly' Slowing Down Older iPhones

Apple now faces over two dozen lawsuits around the world that either accuse the company of intentionally slowing down older iPhones, or at least of failing to disclose power management changes it made starting in iOS 10.2.1.

The lawsuits include 24 class action complaints in the United States, with the latest two filed on Thursday by Marc Honigman and Lauri Sullivan-Stefanou in New York and Ohio respectively, according to electronic court records reviewed by MacRumors. Apple is also being sued in Israel and France.

An excerpt from Sullivan-Stefanou's complaint:

Unbeknownst to iPhone 6, iPhone 6 Plus, and iPhone 6s owners, Apple inserted code into iOS 10.2.1 that deliberately slowed down the processing performance of these phones by linking each phone's processing performance with its battery health. Absent the code inserted by Apple, the reduced battery capacity of these phones would not have negatively affected processing performance.

Many of the lawsuits demand Apple compensate all iPhone users who have experienced slowdowns, offer free battery replacements, refund customers who purchased brand new iPhones to regain maximum performance, and add info to iOS explaining how replacing an iPhone's battery can prevent slowdowns.

The legal action comes after Apple's revelation it may at times dynamically manage the maximum performance of some older iPhone models with chemically aged batteries in order to prevent the devices from unexpectedly shutting down, an issue that can be made worse by cold temperatures or a low charge.

Apple never mentioned the power management changes, which it calls a feature, when it released iOS 10.2.1 nearly a year ago. A month after the software update became available, Apple still only vaguely mentioned that it made "improvements" that resulted in a significant reduction in unexpected shutdowns.

Apple only revealed exactly what the so-called "improvements" were after Primate Labs founder John Poole visualized that some iPhone 6s and iPhone 7 devices suddenly had lower benchmark scores starting with iOS 10.2.1 and iOS 11.2 respectively despite operating at maximum performance on previous versions.

Poole's analysis was in response to a Reddit user who claimed his iPhone 6s was significantly faster after replacing the device's battery. The discussion generated over 1,000 comments, and reinforced an opinion held by some that Apple purposefully slows down older iPhones so customers buy newer ones.

Honigman's complaint, edited very slightly for clarity, echoes this opinion:

Apple's intentional degradation of the iPhone's performance through the release of iOS impacted the usability of the device. Effectively, Apple has forced the obsolescence of iPhones by secretly diminishing their performance. Thus, Apple's admission has confirmed what iPhone users have long suspected – i.e., that Apple deliberately degrades the performance of older iPhone models through iOS updates to encourage users to buy new iPhones.

Apple has since issued an apology for its lack of communication, and it has reduced the price of battery replacements to $29 for iPhone 6 and newer through the end of 2018. Apple has also promised to release an iOS update early this year that will give users more visibility into the health of their iPhone's battery.

Keep in mind that Apple is not permanently or persistently slowing down older iPhones. Even if your iPhone is affected, the performance limitations only happen intermittently, and only when the device is completing demanding tasks.

We recently answered many frequently asked questions about Apple's power management process, which can't be disabled, but can be avoided by replacing your iPhone's battery if necessary. Read our guide on how to get an iPhone's battery replaced at an Apple Store or Apple Authorized Service Provider.

Update: Yisroel Brody on Friday filed at least the 24th class action complaint against Apple in a New York district court.

It's nauseating to realize how many people here said it DIDN'T HAPPEN! Countless people and posts screaming that Apple was being needlessly burned at the stake for something that literally WAS NOT HAPPENING... Yet, surprise, surprise, it was!! I think Apple even denied it at one point - surprise, surprise, they lied! Now, watch the magic of the chorus turning from it never happened to, it did happen and thank god it did! All hail TC!

Didn’t used to happen. They skimped on battery quality from iPhone 6 up.

That's just silliness. No one is okay with a phone that is randomly shutting down, but neither are most okay with their phones being forcibly SLOWED down with absolutely no explanation to the cause. Even more, many of those people INQUIRED of Apple regarding the phone performance only to be told that there was nothing wrong.

Remember VW's lawsuit about secretly altering emissions stats? Are you okay with that? What if a car company advertised a certain level of fuel performance, but as the car aged it no longer met those levels. So the next time you take your car in for an oil change, they tinker with you car and put a governor on the motor that impedes performance, but increases your mileage to their advertised standards. They don't tell you, and when you asked about a certain 'lag' as you push the accelerator, their service underwriter gets in the car, drives it, and says, "Hey, everything seems fine to me."

Are you okay with that? Consumers just want honest, upfront communication, and they are due that as a paying customer.

It’s interesting what Apple considers a “feature” in their products these days (i.e., under Tim Cook’s clueless leadership). Slowing down iPhones is to the point where they are lagging is a “feature.” Removing the headphone jack (which is ubiquitous) is a feature. Removing the home button (which is faster and more ergonomic than the software swipe solutions) is a feature. Removing MagSafe from the MacBook line is a feature. Removing the most commonly used ports from the MacBook line is a feature. Removing skeuomorphic visual cues (which makes learning how to use devices far easier for the elderly and many other people who are new to smartphones and computers) is a feature.
