"Planned obsolescence" gets used as an explanation for almost everything people are annoyed about with their electronics: the phone that slows down right before a new model launches, the laptop battery that won't hold a charge after two years, the printer that insists a cartridge is empty when it isn't. Some of that is exactly what it looks like. A lot of it isn't — it's the ordinary, unglamorous result of chemistry, cost tradeoffs, and support windows that were never designed to be secret. The distinction matters, because only one of those categories is something you can actually shop around.

The case that started the whole idea: a 1924 lightbulb cartel

The term has a real, well-documented origin, and it's not a conspiracy theory. In 1924, the major lightbulb manufacturers of the time — including Philips, Osram, and General Electric's international arm — formed an alliance known as the Phoebus cartel. Its members agreed to cap the lifespan of incandescent bulbs at roughly 1,000 hours, down from the 1,500–2,500 hours bulbs had commonly achieved before, and companies that exceeded the cap were fined. This wasn't a rumor or an internal memo leaked decades later — it was a formal, documented agreement among manufacturers to make a product deliberately worse in order to sell more of it. The cartel dissolved with the outbreak of World War II, but the pattern it established — engineering a shorter lifespan into a product specifically to increase repeat sales — is the original, literal definition of planned obsolescence, and it's the bar people usually mean when they accuse a modern company of doing the same thing.

Almost nothing in modern consumer electronics has been proven to meet that bar as cleanly. What you actually run into is a mix of three different things that get lumped under the same label, and they deserve to be pulled apart.

1. Battery chemistry — real, physical, and not a conspiracy

Every lithium-ion battery degrades with use, and this isn't a design choice a company can simply opt out of — it's a property of the chemistry itself. Each full charge cycle causes small, permanent changes inside the cell, and after roughly 300 to 500 full cycles, most lithium-ion batteries have lost a meaningful share of their original capacity — commonly cited estimates put it around 20%, though the exact number depends heavily on how the device is charged, how hot it runs, and how deeply it's discharged. This is why a three-year-old phone doesn't last as long on a charge as it did on day one, even with identical usage habits.

What companies can influence is how gracefully that degradation is handled. Apple's decision in 2017 to throttle processor speed on iPhones with aging batteries — to prevent unexpected shutdowns as the battery could no longer supply peak current — was a real engineering tradeoff, but the company's failure to clearly disclose it to users at the time turned a defensible technical decision into a genuine trust problem, and it resulted in a settled class-action case and, eventually, a built-in battery health display in iOS so people could see the tradeoff being made on their behalf. That's a useful case study in itself: the underlying physics wasn't the scandal. The lack of a straightforward explanation was.

2. Software support windows — a real deadline, not a hidden one

The second big driver of "my device stopped being usable" is software support ending, and this one actually has gotten meaningfully better and more transparent in the last several years. Apple has historically supported iPhones with major iOS updates for around five to six years from release, and security-only patches sometimes longer. Google guarantees varying update windows by device tier, and Samsung significantly extended its commitment on flagship phones to multiple years of both OS upgrades and security patches. None of this is hidden — it's published, and it's become an actual selling point companies compete on rather than something they try to obscure, precisely because "how long will this get updates" turned into a real purchase-decision factor once people started asking it out loud.

Where this becomes a genuine obsolescence problem is less about the policy and more about the math: a device that's perfectly capable, hardware-wise, of running for another five years can become a security liability the day patches stop, because unpatched software is a real attack surface, not just an inconvenience. That's a legitimate reason to eventually replace a device — but it's a fixed, known date you can check before you buy, not a surprise sprung on you afterward.

3. Repairability — the part that's actually shifting, and fast

This is the category where "the industry is deliberately making things hard to fix" has the most truth to it, and it's also the category where regulation has moved the most in the last few years. Design choices like batteries glued rather than screwed into place, proprietary screws, serialized parts that trigger warnings if replaced by anyone but an authorized shop, and repair manuals that were simply never published all make devices harder to service — and unlike battery chemistry, these are genuine design decisions, not unavoidable physics.

The regulatory response has been real and specific. France introduced a mandatory "repairability index" in 2021, requiring manufacturers to display a score on smartphones, laptops, and other electronics based on documentation availability, ease of disassembly, and spare parts pricing — visible on the box, right next to the price. The EU's broader "right to repair" rules, phased in through 2024 and 2025, require manufacturers to make spare parts and repair information available to independent repair shops, not just authorized ones, for a fixed number of years after a product stops being sold. The EU's battery regulation goes further still, requiring portable batteries in most consumer devices to be user-replaceable by 2027 — directly targeting the glued-in-battery design that's made phone repairs difficult for the better part of a decade. In the U.S., a growing number of states have passed their own right-to-repair laws covering electronics, following earlier laws that targeted agricultural and medical equipment specifically.

None of this fixes a device you already own. But it's changing what gets designed and sold going forward, and it means repairability scores are becoming something you can actually check before buying — rather than something you only discover the hard way when a battery dies two years in and the replacement costs more than the phone is worth used.

What's actually deliberate versus what's just cost engineering

A useful way to sort through any specific complaint is to ask: would fixing this cost the company more money, or would it cost about the same either way? A glued-in battery is usually cheaper and faster to assemble on a production line than a screwed-in one with a removable backing — that's a cost decision that happens to also make repair harder, not necessarily one made to force replacements. A software update that a five-year-old phone simply can't run because it lacks the processing power for a new feature is a real hardware limitation, not sabotage. Compare that to a printer that refuses to print with a third-party cartridge that has plenty of ink left, purely because it doesn't recognize an authentication chip — that's much harder to explain as anything other than a deliberate choice to limit your options after the sale, and it's the kind of practice that's drawn the most direct regulatory and legal scrutiny in the printer and inkjet industry specifically.

The honest pattern across most of consumer electronics is closer to "design for the cheapest reliable assembly, then let natural replacement cycles do the rest" than a coordinated plot to sabotage products — but the effect on your wallet is largely the same either way, which is exactly why it's worth shopping defensively regardless of which explanation is technically more accurate for a given product.

How to actually shop around it

The single most reliable predictor of how long a device will stay useful isn't the brand — it's whether the battery is user-replaceable and whether the manufacturer has published a specific, multi-year software support window for that exact model.

The bottom line

Planned obsolescence, in its strict original sense — deliberately engineering a shorter lifespan purely to force repeat purchases — has one clean historical proof point in the Phoebus cartel, and it's genuinely hard to find modern consumer electronics cases that meet that same bar with the same level of evidence. What you're actually running into most of the time is battery chemistry that degrades on its own schedule, software support windows that are now published rather than hidden, and repair-unfriendly design choices that are more often about manufacturing cost than sabotage — except in the narrower, more clear-cut cases like cartridge authentication chips, where the deliberate-limitation explanation holds up much better. None of that makes the frustration less real. It just means the fix is closer to "check the repairability score and the update commitment before you buy" than "wait for the next scandal."
