The Spectre of Planned Obsolescence: Why Your ZX Spectrum Still Works But Your iPhone Doesn’t

Introduction

I remember the first time I realised my iPhone wasn’t really mine. The battery had started draining within hours, so I booked a Genius Bar appointment. The technician quoted £69 for a replacement, explaining with rehearsed sympathy that opening the device myself would void the warranty and risk damaging other components. I asked why I couldn’t simply unscrew the back panel and swap the battery like I’d done with countless devices before. He smiled politely and said modern engineering required specialist tools and training. What he didn’t say: Apple had deliberately designed the phone to prevent exactly what I was asking. This is planned obsolescence in practice.

That afternoon, sitting in the shopping centre feeling obscurely cheated, I thought about the ZX Spectrum I’d restored the previous week. The air conditioning hummed overhead, mixing with the tinny sound of a mobile phone kiosk demonstrating the latest models on endless loop. I’d bought that Spectrum broken at a car boot sale for a fiver on a grey Sunday morning, spent an evening sorting a faulty voltage regulator chip, and watched it boot perfectly. Total repair cost: 40p plus the quiet satisfaction of bringing something back to life. The Spectrum was 42 years old, built in 1982. My iPhone was three. Yet the ancient machine gave me control. The modern one treated me as someone who needed expert permission to fix my own device.

This represents a fundamental betrayal of consumers and the environment. The engineering philosophy that created 1980s computing hardware assumed users would repair, upgrade, and extend their devices. Modern smartphones and tablets assume the opposite: that technology is temporary, sealed, and designed for replacement cycles measured in months rather than decades. This shift serves manufacturer profit margins beautifully. It serves users and the environment appallingly.

This article examines why 1980s computing hardware remains repairable while contemporary devices languish in landfills. Through component-level analysis, restoration engineer testimonies, and current right-to-repair advocacy, we’ll explore whether disposability serves genuine technical constraints or merely profit margins. The question isn’t whether we should return to rubber keys and cassette loading, but whether modern sophistication must sacrifice user agency and longevity.

Historical Context: How 1980s Design Avoided Planned Obsolescence

The ZX Spectrum’s repairability wasn’t born from charity. It emerged from economic necessity and cultural expectation. In 1982, a Spectrum cost £125 for the 16K model, roughly £475 in today’s money. That represented significant household investment, often saved for over months or bought on hire purchase. Families expected years of service. Manufacturers hadn’t yet embraced planned obsolescence because customers demanded longevity. When something broke, you fixed it rather than replacing it, because replacement simply wasn’t affordable for most households.

Crucially, repair wasn’t confined to technical enthusiasts. High street electronics shops offered accessible repair services for ordinary customers. Tandy, Maplin, and countless independent shops stocked standard components and employed technicians who could diagnose faults whilst you waited. You didn’t need to understand how a voltage regulator worked; you just needed to find someone local who did. This retail repair ecosystem thrived precisely because manufacturers designed devices to be serviceable.

The Spectrum’s circuit board reflects this democratic approach. Remove five screws and the case splits open, revealing a single-layer PCB with through-hole components. The Z80 processor sits in a standard DIP socket, meaning technicians could replace it with a screwdriver and a £3 chip. The RAM chips used industry-standard pinouts. When one failed, any competent repair shop could desolder it and fit a replacement from standard stock without specialist tools or manufacturer authorisation. Sinclair even published complete schematics in the user manual, treating technical transparency as a feature rather than a liability.

This philosophy extended across 1980s British computing. The BBC Micro shipped with a comprehensive technical reference manual. The Amstrad CPC 464 used standard components throughout. Even proprietary custom chips could be sourced from specialist suppliers or salvaged from broken machines. Component standardisation meant a thriving third-party repair ecosystem: local electronics shops stocked common chips, and magazines like Practical Electronics ran repair guides.

The economic impact mattered profoundly to ordinary families. Consider total cost of ownership: a £475 Spectrum (inflation-adjusted) that lasted eight years with perhaps £50 in repairs cost roughly £66 per year. A modern £800 iPhone replaced every three years costs £267 annually, before factoring in increasingly expensive repairs that Apple deliberately makes difficult to obtain elsewhere. Over a decade, the repairable model saves families over £2,000, money that disproportionately affects lower-income households already stretched by technology costs.

I’ve restored dozens of Spectrums, and parts remain readily available four decades later. The voltage regulator (a 7805) costs 40p. Cheap as chips, and you can sort it in an evening with a soldering iron and a magnifying glass. The ULA (Uncommitted Logic Array) chip is harder to find but exists in online retro parts stores. Compare this to a 2020 iPhone logic board, where the A14 processor, RAM, and storage are soldered together in a single package-on-package assembly. When that fails, you replace the entire board, losing all data and spending several hundred pounds.

The generational relevance cuts deeper than nostalgia. Gen-X consumers remember when ownership meant control. Adding RAM to your Spectrum meant following a magazine guide. Worn rubber keys? Replace the keyboard membrane yourself. Broken equipment went to the local shop and came back repaired three days later for a reasonable fee. This relationship with technology wasn’t about technical prowess; it was about agency, dignity, and not being held hostage by manufacturers. Opening a machine wasn’t warranty fraud. It was expected ownership and user empowerment.

Modern Implications: Planned Obsolescence as Business Model

The shift towards disposability didn’t happen overnight. It emerged gradually through the 1990s and accelerated dramatically in the smartphone era. Three forces drove this transformation: miniaturisation, profit model evolution, and consumer acceptance.

Miniaturisation gave genuine engineering reasons. Moving from through-hole to surface-mount components allowed smaller, lighter devices. The original iMac in 1998 still used modular components, but the 2007 iPhone required entirely different construction. Fitting a computer into a pocket demanded integrated circuits, soldered assemblies, and adhesive bonding. Apple argued that screws created bulk and weakened water resistance. These aren’t trivial concerns; they represent real design trade-offs.

But miniaturisation doesn’t mandate planned obsolescence. The Framework Laptop, released in 2021, achieves modern performance in a slim profile while maintaining modular construction. Every component, from RAM to WiFi cards to the display, uses standard connectors. You can replace the motherboard and keep the same chassis. Framework proves that repairability and contemporary engineering can coexist, which makes the choices other manufacturers make look less like necessity and more like strategy.

The profit model shift towards planned obsolescence matters more than technical constraints. Modern tech companies discovered that disposable devices generate predictable revenue streams. Apple’s battery replacement controversy in 2017 exposed this clearly. The company admitted throttling older iPhones when batteries degraded, ostensibly to prevent unexpected shutdowns caused by ageing lithium-ion cells. The technical explanation holds some merit: as lithium-ion batteries age, internal chemical breakdown generates gas buildup, causing swelling and reduced capacity. Older cells struggle to deliver peak current, potentially causing voltage drops that crash processors.

Yet instead of designing easily replaceable batteries, Apple used proprietary pentalobe screws, adhesive strips requiring heat guns to remove, and software warnings to discourage user repairs. Absolute bodge of a design if you’re trying to maintain it. An iPhone 8 battery replacement at an Apple Store costs £69, despite the battery itself costing under £15. Independent repair shops face parts scarcity, serialised components that reject third-party replacements, and legal threats under warranty void stickers. Apple later introduced parts pairing, where batteries, displays, and Face ID sensors are digitally locked to the device logic board. Replace a battery with a genuine Apple part from another iPhone and the device displays persistent warnings about “unknown parts”, even though the battery is identical and authentic.

Samsung follows similar patterns. The Galaxy S21’s display uses adhesive bonding strong enough to crack the screen during removal. The battery connects via a delicate flex cable prone to tearing. Even after successful hardware replacement, Samsung’s Knox security system permanently marks the device as modified, disabling certain features like Samsung Pay. Knox serves legitimate security functions, but it also creates artificial repair penalties that have nothing to do with device integrity. Replace a cracked screen and lose financial services permanently, even though the repair doesn’t compromise security hardware.

Modern devices also complicate repair through thermal management requirements. High-performance processors generate significant heat that requires careful dissipation design. Poorly executed repairs can compromise thermal paste application, heatsink contact, or airflow paths, potentially causing overheating and component damage. Manufacturers claim this justifies restricting repairs to authorised centres. Yet companies like Framework demonstrate that good documentation solves this challenge. Framework publishes detailed thermal system guides and provides properly sized thermal pads with replacement parts. These complications serve planned obsolescence whether manufacturers admit it or not. The engineering problem is solvable; manufacturer will to solve it remains absent.

The environmental cost grows staggering. The UN estimates that 53.6 million metric tonnes of electronic waste were generated in 2019, with only 17.4% formally collected and recycled. Smartphones contain rare earth minerals, conflict materials, and toxic compounds. A repairable phone used for six years generates far less environmental harm than three sealed devices across the same period. Yet manufacturers continue treating devices as consumables, with upgrade cycles driven by marketing rather than technical obsolescence.

Consumer frustration mounts alongside the waste. We’ve become accustomed to ownership without control. MacBook keyboards can’t be replaced without replacing the entire top case, battery, and trackpad assembly because Apple spot-welds them together. Surface tablet storage can’t be upgraded because it’s soldered. AirPods can’t be repaired at all; Apple classes them as disposable. This erosion of ownership rights feels like theft by degrees. My father’s 1978 Marantz amplifier still functions perfectly and has been repaired three times. His grandson’s wireless earbuds died after 18 months with no repair possible. What does this longevity gap teach younger generations about the value of objects and environmental responsibility?

Future Outlook: Reversing Planned Obsolescence

Hope exists in both legislative action and market alternatives. The right-to-repair movement has achieved remarkable progress recently, transforming from fringe advocacy to mainstream policy discussion. Resistance to planned obsolescence is growing.

The European Union led this resistance. In March 2024, the EU Parliament passed comprehensive right-to-repair legislation requiring manufacturers to offer spare parts, repair manuals, and reasonable pricing for electronics. Phones, tablets, and laptops sold in EU markets must now provide battery replacement options, use standard screws rather than proprietary fasteners, and avoid software locks preventing third-party repairs. The regulations take full effect in 2026, with significant penalties for non-compliance.

The UK followed cautiously. Parliament debated similar legislation in late 2024, with cross-party support from MPs frustrated by constituent complaints. The proposed UK Right to Repair Act would match EU standards but add requirements for minimum device lifespan transparency. Manufacturers would declare expected support periods at sale, allowing consumers to make informed choices. Industry lobbying delayed the bill, but momentum continues building.

Louis Rossmann, the New York repair technician and YouTuber, deserves particular credit for mainstreaming this issue. His detailed teardown videos expose deliberate repair obstacles, from serialised components to firmware blocks. He’s testified before US state legislatures, framing repair restrictions as anti-competitive practice and environmental vandalism. His advocacy helped pass right-to-repair laws in New York, California, and Minnesota, creating pressure that even Apple can’t entirely ignore.

The market provides examples of what repairable modern devices could achieve. The Fairphone 5, released in 2023, offers modular construction with user-replaceable battery, camera, display, and USB port. Components snap together with simple clips and standard screws. Fairphone commits to eight years of software updates and ten years of spare parts availability. The device costs £699 upfront versus £479 for comparable Android phones, but over eight years of use, avoiding even one replacement saves £280. Total cost of ownership calculation: Fairphone costs £87 per year; comparable sealed phones replaced twice cost £160 annually. Families choosing repairability save nearly £600 over realistic device lifespans.

Framework’s modular laptop ecosystem expands further. Their 16-inch model achieves professional-grade performance whilst maintaining complete repairability. Yes, it measures 15.85mm thick (versus 14mm for comparable sealed ultrabooks) and weighs approximately 100g more. But CPU performance matches sealed competitors exactly; you sacrifice nothing functionally. You can upgrade from Intel to AMD by replacing the motherboard and keeping everything else. Framework publishes complete design files and circuit diagrams, actively encouraging third-party module development. Their marketplace already offers alternative port configurations, graphics upgrades, and specialised modules that traditional manufacturers would never support. This proves conclusively that modular design doesn’t require performance compromise, only manufacturer commitment.

iFixit, the repair guide and parts supplier, publishes repairability scores for major devices. Modern iPhones score between 4/10 and 7/10 depending on model, representing deliberate regression from early iPhones that scored higher before Apple committed to sealed design philosophy. Framework laptops score perfect 10/10s. These scores create consumer pressure and embarrass manufacturers into gradual improvements, though progress remains frustratingly slow.

What can readers do? Support repair-friendly manufacturers financially. Buy Fairphone or Framework if they meet your needs. Demand that traditional manufacturers commit to repairability: write to Apple, Samsung, Microsoft expressing concern. Support right-to-repair legislation: contact your MP, sign petitions, donate to advocacy groups. Learn basic repair skills: iFixit offers guides for thousands of devices, making battery replacements and screen fixes accessible. Extend device lifespan: security updates matter more than marketing hype.

Conclusion

I’m writing this on a 2015 MacBook Air that Apple would prefer I replaced five years ago. The SSD failed last year. Apple quoted £480 for a logic board replacement, explaining with rehearsed sympathy that the storage was soldered and couldn’t be swapped independently. I found a third-party adapter and compatible SSD for £85, spent an evening following iFixit guides, and sorted it myself. Apple designed this repair to be impossible. I did it anyway, but I shouldn’t have needed to fight my device’s manufacturer to maintain my own property.

Standing in my workshop surrounded by three decades of computing hardware, the contrast feels like generational theft. My 1982 ZX Spectrum, 1985 Amstrad CPC 464, and 1989 Amiga 500 all function because their designers treated longevity and repairability as features worth honouring. The 7805 regulator I replaced last month cost 40p. The RAM chip before that, salvaged from another board, cost nothing. These machines respect their users enough to assume we deserve agency.

Modern manufacturers treat planned obsolescence as profit worth maximising. Gen-X consumers remember the before times. Younger generations never experienced ownership without surveillance, agency without permission, or technology that respected its users. My nephew asked me last week why his phone slowed down after eighteen months. I had to explain that the manufacturer profits when he upgrades. He looked genuinely betrayed.

The disposable technology model serves manufacturers far better than users or the environment. Miniaturisation and sophistication don’t require sealed, unrepairable designs. Framework and Fairphone prove that alternatives to planned obsolescence exist. The question isn’t technical feasibility but economic priority, manufacturer respect for customers, and legislative will to enforce that respect.

The spectre of planned obsolescence haunts our relationship with technology, transforming ownership into temporary rental and consumers into supplicants. Yet resistance grows through right-to-repair legislation, market alternatives, and mounting consumer fury. We don’t need to return to rubber keys and cassette loading, but we can demand that modern sophistication include user control and environmental responsibility. We can refuse to accept that progress requires disposability.

Technology should empower users, not trap them in endless upgrade cycles driven by planned obsolescence. The ZX Spectrum still boots because its creators respected their customers enough to assume they deserved agency. Modern manufacturers should rediscover that principle before legislative action forces their hand. The future of computing depends not on quarterly replacement cycles but on sustainable, repairable machines that serve users across years, grant genuine ownership, and acknowledge that environmental responsibility matters more than planned obsolescence profits.
