In December 2017, a Reddit user named Teckfire posted benchmark scores showing that Apple’s iPhones slowed down measurably after iOS updates. Within 48 hours, the post had been viewed millions of times. Apple confirmed the practice days later, describing it as a battery management feature designed to prevent unexpected shutdowns. The company eventually paid $500 million to settle class-action lawsuits in the United States and faced regulatory fines across Europe. What got less attention than the scandal itself was how quickly Apple returned to the same practice, under a different name, with better disclosure language buried in a settings menu. The slowdown continued. The lawsuits stopped.

Tech Companies Intentionally Design Software to Die in Five Years and the Business Logic Is Airtight

The Technical Argument Is Real, and That’s the Problem

The frustrating truth is that Apple’s original technical justification was not entirely wrong. Lithium-ion batteries degrade over charge cycles. A degraded battery cannot supply the sudden current spikes that a fast processor demands. When the battery cannot deliver, the phone shuts down unexpectedly, which is genuinely worse than running slowly. Throttling CPU performance to match a battery’s reduced output capacity is a defensible engineering decision.

But the engineering logic and the business logic arrived at exactly the same destination, which is a phone that feels noticeably slower than it did eighteen months earlier. That coincidence is where the real story lives.

Android manufacturers face the same battery physics. Samsung, Google, and OnePlus have all implemented similar throttling mechanisms, each with varying degrees of transparency. A 2023 analysis by the French consumer watchdog HOP (Halte à l’Obsolescence Programmée) found that software updates from multiple Android manufacturers reduced performance on devices older than two years, even on phones with healthy batteries. The pattern held across brands, across operating systems, and across market segments.

The legal protection these companies enjoy is built on three overlapping pillars, and each one is sturdier than it looks.

First, terms of service agreements grant manufacturers broad authority to push software updates that modify device behavior. Users consent to these terms during setup, usually by tapping through screens they do not read. Courts have generally upheld these agreements as enforceable contracts, even when the changes materially affect device performance.

Second, disclosure requirements in most jurisdictions are satisfied by any written notice, regardless of how prominently it is displayed. Apple added battery management language to its iOS support documentation and a toggle in the settings menu. Regulators in several countries accepted this as adequate disclosure. The $500 million settlement Apple reached represented roughly four days of the company’s revenue at the time, a number that reads more like a compliance cost than a deterrent.

Third, and most importantly, manufacturers have successfully framed performance management as a safety and reliability feature rather than a commercial strategy. This framing shifts the regulatory conversation from consumer protection to product quality, a much friendlier legal environment. When the European Union’s right-to-repair legislation began advancing in 2023, manufacturers lobbied successfully to carve out software update practices from its core provisions.

This strategy of using technical justification as legal cover follows a broader pattern in how tech companies structure their decision-making. As explored in our piece on how tech companies engineer their own products to die on a schedule, the line between product lifecycle management and planned obsolescence is deliberately blurry, because that ambiguity is commercially valuable.

The Business Math Behind the Slowdown

Consider the upgrade cycle economics. The average smartphone replacement cycle in the United States was approximately 2.5 years in 2017. By 2022, it had stretched to 3.8 years, driven partly by rising device prices and partly by consumers who felt their older phones still worked adequately. For a company like Apple, which derives a significant portion of revenue from iPhone sales, a longer replacement cycle directly compresses revenue.

A phone that runs noticeably slower after two years is a phone whose owner begins to consider upgrading. Research from Consumer Intelligence Research Partners consistently shows that perceived performance degradation is among the top three reasons consumers cite when replacing a smartphone that is still technically functional. The phone did not break. It just stopped feeling fast.

This is not purely speculative. Internal documents surfaced during the Apple battery throttling litigation showed that the company had modeled the relationship between battery health, perceived performance, and upgrade intent. The documents were not a smoking gun, they did not show executives ordering deliberate slowdowns for commercial purposes, but they demonstrated that the connection between device performance and consumer upgrade behavior was being tracked and analyzed at a senior level.

The dynamic mirrors what we have documented in tech giants losing money on purpose to win markets, where short-term technical decisions are structured to produce long-term commercial outcomes, with enough plausible deniability built into the engineering rationale to survive regulatory scrutiny.

What Transparency Actually Looks Like (When It’s Forced)

The clearest case study in compelled transparency comes from France. In 2018, the French government passed a law specifically criminalizing planned obsolescence, with penalties of up to two years imprisonment and fines of up to five percent of annual revenue. Apple subsequently introduced a dedicated Battery Health section in iOS settings for French users before expanding it globally, likely calculating that the cost of global implementation was lower than the legal risk of maintaining separate software behavior by jurisdiction.

The feature that resulted, the Battery Health and Charging screen that now ships with every iPhone, is genuinely useful. It tells users their battery’s maximum capacity and offers a clear explanation of performance management. It also includes an option to disable throttling and accept the risk of unexpected shutdowns. The information was available only after regulatory pressure made concealment more expensive than disclosure.

This pattern, where transparency arrives only when enforcement costs exceed the benefits of opacity, is consistent across the industry. It raises a reasonable question about how much additional transparency exists in developer and engineering practices that have not yet faced equivalent regulatory pressure. The observation connects to a broader pattern documented in tech companies building features they never release for strategic reasons, where what is technically possible and what is commercially released are two very different things.

What You Can Actually Do

The practical options available to consumers are more substantial than most people realize. Battery replacement, which costs approximately $99 at an Apple Store or significantly less at a reputable third-party shop, restores a degraded battery to near-new capacity and effectively eliminates the performance throttling triggered by battery health metrics. Independent studies have consistently shown that battery replacement returns two-year-old iPhones to benchmark scores within five percent of their original performance.

On Android, third-party tools like CPU-Z and AnTuTu can benchmark your device before and after major software updates, giving you documented evidence of performance changes. This data is not actionable in most legal contexts, but it creates an informed basis for upgrade decisions rather than a reactive one driven by manufactured dissatisfaction.

The deeper takeaway is not about any single company or any single practice. It is about understanding that the software running on your device is not a neutral utility. It is a commercial product, updated by organizations with precise financial incentives, operating inside a legal framework that was largely designed before these incentives became structurally significant. Knowing that does not change the terms of service. But it changes how you read the slowdown.
