Modular smartphone

Modular smartphones promise repairable phones — but deliver compromises that make them impractical for most users.

Modular smartphones let users swap components without tools or services. They aim to fight planned obsolescence and cut e-waste. But they are bulkier, slower, and less sturdy than conventional phones. Their sustainability benefits remain unproven. Open-source sourcing and self-repair work — but not well enough to displace integrated devices.

The written brief1 min read

What it is and the problem it solves

A modular smartphone is a device designed for user-level upgrades and replacements of components without soldering or repair services. It solves the problem of forced replacement by extending lifespan and lowering repair costs.

How it works

A modular smartphone has a main board to which users attach peripheral modules like cameras and batteries. Components are sourced from open-source hardware stores. Users swap modules without soldering or repair services.

What works

Modularity enables self-repair, reduces need for full-device replacement, and supports sustainability claims through repairability and lower replacement frequency.

What does not

Modular smartphones are bulkier and slower than non-modular counterparts. They suffer reduced sturdiness and power inefficiency due to longer inter-component distances and imperfect integration.

What it changes

It shifts repair from service centres to users, bypassing labour costs and enabling self-repair. It challenges planned obsolescence — a strategy originating with Brooks Stevens that prioritises replacement over repair.

Is it worth your time

Not yet. Bulkiness, slowness, and power inefficiency undermine usability. Sustainability claims lack verification on net e-waste reduction. Consumer preference and carrier incentives still favour integrated devices.

Mobile robotA mobile robot is a locomotive, automatic machine—not fixed, not necessarily intelligent. It works by combining controller, sensors, actuators and power. It succeeds where movement and environment match. It fails when autonomy is assumed but not engineered. It changes infrastructure from static to relocatable. It is worth your time if you need machines that move—not just compute.

Brain–computer interfaceBCIs decode brain signals to operate devices. They work in controlled settings for specific users—cursor control since 1977, robots since 1988, intracortical prostheses since 1998, and artificial hands since 2005. But they remain low-bandwidth, unstable, and clinically niche. No general-purpose interface exists.

ChipletChiplets are modular ICs—functional fragments designed for assembly on an interposer. They enable heterogeneous integration, pre-test validation, and IP reuse. But they shift complexity from fabrication to integration, and require standards compliance to deliver on their promise.

Computer numerical controlCNC replaced punched-tape numerical control with computer-driven instruction sets. It shifted manufacturing from fixed logic to editable code—making parts repeatable, but not autonomous. Its success came from falling computing costs, not new physics or AI.
