Your phone is two years old. The battery barely makes it to lunch. The screen has a hairline crack you've learned to ignore. And the repair quote? More than the phone is worth.
So you buy a new one. Multiply that by a billion people, and you start to see the problem.
The average smartphone lasts just two to three years in developed markets, according to GSMA Intelligence—and it usually doesn't die. It gets killed, by a degraded battery or a cracked screen that costs too much to fix.
A modular smartphone flips that equation. Instead of sealing everything into a glued-shut slab, it lets you swap individual parts—battery, camera, screen, USB-C port—using basic tools. Something breaks, you replace that one component. No new phone required.
The idea has been around for over a decade. Google spent years and a reported $100 million on Project Ara before killing it in 2016. Motorola's Moto Mods came and went. LG's G5 flopped. For years, modular phones looked like a cautionary tale.
But something shifted. The Fairphone 5 earned a perfect 10/10 repairability score from iFixit. The EU passed right-to-repair rules. Samsung started selling self-repair kits. The question is no longer whether modular phones can exist—it's whether they can finally go mainstream.
Here are seven reasons modular smartphones are rising, and the honest obstacles still in the way.
The numbers are ugly. In 2019, the world generated 53.6 million metric tonnes of e-waste, and only 17.4% of it was formally recycled, according to the UN's Global E-waste Monitor 2020. Smartphones are a small slice by weight but a big one by value—and by volume of devices.
Modularity attacks the problem at the source. If a phone's lifespan stretches from two years to five or six, you've cut its environmental footprint roughly in half before recycling even enters the picture. Fewer new devices means less mining, less manufacturing, less shipping.
This is circular economy thinking in practice: keep products in use longer, repair what breaks, and recycle only when a device truly reaches end of life.
Fairphone built its entire brand on this premise. The Dutch company uses ethically sourced materials, pays bonuses to factory workers, and designs phones specifically so owners can keep them running. It's a small player, but it's proving the model works.
Key Takeaway: E-waste is a design problem as much as a disposal problem. Modular phones keep devices out of drawers and landfills by making repair the default, not the exception.
For years, repairability was a consumer preference. Now it's becoming law.
The European Union's right-to-repair legislation, including the Ecodesign for Sustainable Products Regulation (ESPR), requires manufacturers to provide spare parts for 5 to 10 years after purchase for certain products—with smartphones in scope by 2027, per the European Commission. That's not a suggestion. It's a requirement tied to market access.
Manufacturers are responding. Samsung partnered with iFixit to sell self-repair kits for Galaxy devices, shipping genuine parts, tools, and guides directly to customers. Apple launched its own Self Service Repair program. Neither company makes a modular phone, but both are now designing for disassembly in ways they weren't five years ago.
When regulators force spare parts to exist, modular design stops being a philosophical choice and starts being an engineering shortcut.
Key Takeaway: Regulation is doing what consumer demand alone couldn't. When spare parts must be available for a decade, building phones that are easy to open becomes the path of least resistance.
If modular smartphones have a proof of concept, it's the Fairphone 5.
The device has 10 user-replaceable components, including the battery, screen, camera modules, USB-C port, and speakers. You need one standard screwdriver—no heat gun, no suction cups, no adhesive. iFixit gave it a 10/10 repairability score in 2023, the highest possible.
Fairphone isn't just repairable. It's built to last, with a promised eight years of software support—unusual in an industry where three to five years is standard.
The catch is scale. Fairphone's previous model, the Fairphone 4, sold over 100,000 units by 2022, according to the company's own impact report. That's real growth for a niche player and a rounding error for the global smartphone market, which ships over a billion units a year.
Availability is another limit. Fairphone sells primarily in Europe, with limited reach elsewhere. If you're in the US, getting one takes effort.
Key Takeaway: Fairphone proves modular phones can be well-made, genuinely repairable, and desirable. What it hasn't proven is that they can sell at scale.
Modular phones have failed before, and the reasons matter.
Google's Project Ara was the most ambitious attempt: a phone made of swappable blocks—camera, battery, processor—that users could reconfigure at will. Google invested over $100 million before cancelling it in 2016, per The Verge. The technical problems were brutal: keeping modules connected reliably, managing power across separate components, and making the whole thing thin enough to compete with conventional phones.
Motorola's Moto Z took a different approach—magnetic "Moto Mods" that snapped onto the back, including a projector, a Hasselblad camera module, and extended batteries. The line sold fewer than 5 million units combined, according to Counterpoint Research—far below what Motorola needed to sustain the ecosystem.
LG's G5 tried a "Magic Slot" for accessories like a camera grip and a dedicated DAC. Poor sales and build-quality complaints killed it within a year.
The pattern is consistent: modularity adds complexity, and complexity costs money. If the modules don't sell, the ecosystem collapses—and without an ecosystem, the phone has no reason to exist.
Key Takeaway: The failures weren't about the idea. They were about execution, economics, and the difficulty of convincing people to buy accessories they'd never needed before.
There's a reason phones are glued shut. It's not malice—it's physics.
Size and weight. Modular connections need space. A removable battery needs a housing, a latch, contacts. That's volume a sealed design doesn't spend.
Durability and water resistance. Every seam is a potential failure point. The Fairphone 5 carries an IP55 rating—decent against dust and splashes, but a step below the IP68 ratings common on flagship phones. Water and modularity are uneasy roommates.
Processor upgrades. This was Project Ara's dream, and it remains mostly unrealized. Swapping a CPU means dealing with the motherboard, memory, thermal design, and software compatibility. No current modular phone offers it.
Cost. Modular phones often cost more upfront than comparable conventional devices. The savings come later—if you keep the phone long enough and actually replace parts instead of replacing the whole thing.
Key Takeaway: Modularity is a trade-off, not a free upgrade. You gain repairability and longevity; you give up some thinness, waterproofing, and sometimes raw performance.
The most successful modular device of the past five years isn't a phone. It's a laptop.
Framework built a business on modular notebooks—swappable ports, replaceable screens, upgradable motherboards. The company's pitch is simple: buy once, upgrade forever. It's worked well enough to spawn a growing product line and a devoted following.
Framework hasn't made a smartphone. But its success has shifted how people think about modular consumer electronics. The lesson isn't that modular phones are easy—it's that a focused company with a clear audience can make modularity work commercially.
Other attempts haven't fared as well. PuzzlePhone and Phonebloks (which started as a concept video) never reached mass production. Shiftphone, a German company, sells modular smartphones with replaceable components, but it's even less known than Fairphone.
The field is thin, but it's not empty—and Framework's example suggests the model can scale with the right execution.
Key Takeaway: Framework proved modular design can be a viable business, not just a sustainability statement. The phone industry is watching.
As of 2024, no major manufacturer—Apple, Samsung, Google—offers a fully modular flagship phone. That's unlikely to change overnight.
What is changing is repairability. iFixit scores are climbing. Self-repair programs are expanding. The EU's rules are forcing spare parts into existence. The direction of travel is clear, even if the destination isn't a fully modular iPhone.
The likeliest future is hybrid design: phones with some user-replaceable components—battery, screen, maybe the charging port—but not swappable processors or cameras. That's a middle path that satisfies regulators, reduces e-waste, and doesn't ask manufacturers to abandon everything they know about building thin, sealed devices.
Consumer pressure matters too. Every person who checks a repairability score before buying sends a signal. Every repair instead of replacement does the same.
Key Takeaway: Full modularity may stay niche. But partial modularity—replaceable batteries, accessible screens, available parts—is becoming the baseline, not the exception.
Not yet. Fairphone leads the category, but it remains a small European company selling to a niche audience. The big players haven't committed to full modularity, and the technical trade-offs are real.
But the momentum is genuine. Regulation is forcing change. Repairability is becoming a selling point. The failures of Project Ara and the Moto Z taught the industry what doesn't work, and companies like Fairphone and Framework are showing what does.
Mainstream? No. On the rise? Absolutely.
The next time you buy a phone, check its repairability score. Look for replaceable parts. Support the right-to-repair movement. The more people who care, the faster the industry responds.
What is a modular smartphone? A phone designed so users can replace or upgrade individual components—battery, screen, camera, ports—rather than replacing the entire device.
Are modular smartphones mainstream today? No. As of 2024, no major manufacturer offers a fully modular flagship. Fairphone is the leading modular brand, but it sells primarily in Europe at a fraction of global volume.
Why did Google's Project Ara fail? Technical challenges—reliable module connections, power management, size—combined with uncertain consumer demand. Google cancelled it in 2016 after investing over $100 million.
Which companies currently make modular smartphones? Fairphone is the most prominent. Shiftphone and Teracube also make modular or highly repairable phones, though they're smaller players.
What are the benefits of modular smartphones? Longer device lifespan, lower long-term cost, reduced e-waste, and easier repairs without professional service.
What are the drawbacks? Bulkier designs, weaker water resistance, limited upgrade options for core components like processors, and higher upfront prices.
How does the EU right-to-repair law affect modular smartphones? It requires manufacturers to provide spare parts for 5–10 years for certain products, including smartphones by 2027—pushing design toward repairability and modularity.
Is the Fairphone available worldwide? No. Fairphone sells primarily in Europe, with limited availability elsewhere. US buyers face extra hurdles.
Will Apple or Samsung ever make a modular phone? A fully modular flagship is unlikely soon. But both companies are improving repairability and offering self-repair programs, which is a step in that direction.
What is the future of modular smartphones? Hybrid designs—partially modular with replaceable batteries and screens—are the most probable outcome, driven by regulation and consumer demand.
