The Return of Modular Smartphones? Xiaomi’s Foldable Could Spark a Revolution
Smartphone enthusiasts remember a time when modular phones promised to change everything. Google’s Project Ara and Motorola’s Moto Z series generated excitement, but ultimately failed to gain mainstream traction. The Fairphone emerged as a more sustainable alternative, but remains a niche product. Now, a new contender – Xiaomi’s upcoming Mix Fold 5 – could reignite the conversation around modularity.
What is Xiaomi Cooking Up?
Leaks suggest the Xiaomi Mix Fold 5 is being developed with a magnetic modular camera system. This would allow users to swap, adjust, or upgrade camera modules, attaching a better lens or a specialized one for specific needs (Gizchina).
This system would mimic the interchangeable lenses found on professional cameras. If successful, it could be one of the most exciting camera hardware innovations in years, following Xiaomi’s physical zoom ring on the Xiaomi 17 Ultra. However, the success of such a system isn’t guaranteed.
Smart Idea or a Complicated One?
Foldable phones often feature slightly less advanced camera systems compared to a brand’s conventional flagship models. A modular system could address this limitation. However, foldables currently have lower sales volumes than traditional smartphones, potentially limiting the reach of this technology.
Fortunately, Xiaomi is developing the modular lenses in-house, rather than relying on a third-party manufacturer.

The History of Modularity: Lessons Learned
The concept of modular smartphones isn’t new. Project Ara, initiated by Google in 2013, aimed to create a phone with hot-swappable modules for components like batteries, cameras and processors. However, the project was abandoned in 2016 due to challenges with durability, interoperability, and consumer appeal. Motorola also experimented with modularity through the Moto Z series, but it didn’t achieve widespread adoption. The Fairphone series, however, has continued to champion modularity, focusing on repairability and sustainability (TechRadar).
Why Modularity Matters: A Sustainable Future?
The appeal of modular smartphones lies in their potential to extend the lifespan of devices. By allowing users to upgrade individual components, rather than replacing the entire phone, modularity could reduce electronic waste and promote a more sustainable approach to technology. This aligns with growing consumer demand for eco-friendly products and right-to-repair initiatives. The ability to easily repair or upgrade a phone could also save consumers money in the long run.
Beyond Cameras: The Potential of Future Modules
While Xiaomi’s focus is currently on modular cameras, the possibilities extend far beyond. Future modules could include:
- Battery Modules: Swap in a larger battery for extended use.
- Storage Modules: Increase storage capacity as needed.
- Sensor Modules: Add specialized sensors for specific applications (e.g., environmental monitoring).
- Connectivity Modules: Upgrade to the latest connectivity standards (e.g., 6G).
