In 2025, wearable technology has entered a new era—one not defined solely by faster processors, crisper displays, or smarter health metrics, but by a quieter revolution: repairability. While consumers have long celebrated innovation in devices like smartwatches, fitness trackers, and AR glasses, there’s a growing awareness that these marvels often come with a hidden cost: short lifespans and sealed components that make repair nearly impossible. Among these, one issue stands out as both a technical and environmental challenge—non-replaceable batteries.
Why Repairable Wearables Are Making Headlines
Wearables are no longer fringe gadgets; they’re integral to everyday life. The global market for smartwatches and fitness trackers has grown exponentially, driven by health-conscious users who monitor everything from heart rhythms to sleep quality. Yet, despite their high-tech promise, many devices end up in landfills within just three to four years. Why? Because lithium-ion batteries—the beating heart of these devices—degrade over time, and when they fail, replacing them often means replacing the entire product.
In 2025, consumer sentiment has shifted sharply. Influenced by right-to-repair movements, environmental concerns, and the rising cost of premium devices, buyers are beginning to demand Repairable Wearables with user-replaceable or easily serviceable batteries. Governments in Europe and parts of Asia are even draughting legislation requiring consumer electronics to meet minimum repairability standards, echoing earlier rules for smartphones and laptops.
The Technical Challenge of Battery Replacement in Wearables
Unlike smartphones, which have space for modular design, wearables are notoriously compact. Their batteries are custom-shaped, glued or soldered into tight frames, and often sealed to meet waterproofing standards. Adding screws or removable panels risks compromising durability or bulk, which manufacturers have historically resisted.
However, recent breakthroughs are making this trade-off less painful. Ultra-thin sealing gaskets, low-profile connectors, and nano-coating technologies allow companies to design water-resistant yet serviceable devices. Brands like Fairphone in smartphones have proven that modular design can succeed without sacrificing performance. In wearables, pioneers are adopting similar strategies—snap-in batteries, standardised charging contacts, and simplified opening mechanisms.
Environmental and Economic Implications
The environmental argument is impossible to ignore. Electronic waste (e-waste) is projected to exceed 75 million metric tonnes by 2030, according to the Global E-Waste Monitor, and small electronics like wearables are a growing contributor. Non-replaceable batteries accelerate this problem by turning functional devices into disposable items once the battery depletes.
From an economic perspective, devices with swappable batteries extend their usable life, reducing the need for frequent upgrades. Consumers benefit from long-term value, while companies can create recurring revenue through selling certified replacement batteries rather than entirely new devices. This model mirrors industries like cameras and handheld gaming, where replaceable batteries have long been standard.
How Leading Brands Are Responding
- Apple and Samsung:
While Apple Watch and Galaxy Watch remain industry leaders, both brands have been slow to embrace full repairability. Their designs still rely on adhesives, making battery replacement a delicate and costly service. However, under regulatory pressure, Apple has begun offering official repair manuals and battery replacement programmes, while Samsung has signalled interest in more modular designs for future Galaxy Watches. - Garmin and Suunto:
These brands, popular among athletes, are experimenting with hybrid approaches. Some models now feature accessible battery compartments, though often limited to niche or rugged devices where field replacement is critical. - Framework and Fairphone’s Influence:
While not major players in wearables, companies like Framework (laptops) and Fairphone (smartphones) are influencing design philosophy. Their ethos—modularity, repairability, and sustainability—is inspiring a new generation of wearable startups to rethink sealed designs. - Emerging Players:
Startups in Europe and Japan are releasing repair-first smartwatches with tool-free battery access. These devices may lack the polish of premium brands but appeal to environmentally conscious buyers who prioritise longevity over luxury.
Competitor Comparisons: Repairability vs. Features
Consumers now face a meaningful choice:
- Premium sealed wearables (Apple Watch Ultra, Galaxy Watch 7) still lead in aesthetics, software, and health-tracking sophistication but require professional service or outright replacement when batteries fail.
- Repairable mid-tier wearables offer slightly fewer features or bulkier designs but can last 2–3 times longer thanks to user-serviceable batteries.
- Ultra-rugged field watches (Garmin Enduro, Casio Pro Trek) already integrate accessible battery systems because professionals and adventurers demand reliability over sleekness.
The decision comes down to longevity vs. polish. Increasingly, educated consumers are realising that a sleeker case is a poor trade-off for a device destined to fail prematurely.
Buying Considerations in 2025
If you’re considering a wearable this year, here’s how to assess whether it’s truly built to last:
- Check for Battery Replacement Options
Look for official documentation or teardown reviews showing whether the battery can be replaced by the user or a certified service at reasonable cost. - Evaluate Warranty and Support
Some brands now offer extended battery service programmes—a sign they’re acknowledging battery degradation as an expected reality. - Look for Modular or Open-Design Certifications
Labels like iFixit repairability scores or EU repairability ratings can help you identify which devices are service-friendly. - Balance Performance With Longevity
Ask yourself: do you really need the absolute latest features, or would you rather invest in a wearable that stays functional for 6–8 years instead of 3–4? - Consider Total Cost of Ownership
A slightly higher upfront cost for a repairable wearable may save money in the long run compared to repeatedly replacing sealed devices.
The Broader Movement: Right-to-Repair Meets Consumer Tech
The push for repairable wearables is part of a wider cultural shift. Across electronics, consumers are pushing back against throwaway culture. The EU’s Digital Product Passport, set to roll out by 2026, will require manufacturers to disclose repairability information, expected lifespan, and recycling instructions. Meanwhile, U.S. states are passing right-to-repair laws covering consumer electronics, pressuring major brands to adapt before global regulations catch up.
This isn’t just about fixing batteries. It’s about reshaping the entire consumer-tech ecosystem to prioritise sustainability, transparency, and user control. Wearables are simply the latest—and most personal—front in this ongoing battle.
What’s Next for Repairable Wearables?
Looking ahead, several innovations promise to make wearables both high-performance and repair-friendly:
- Solid-state batteries with slower degradation, reducing replacement frequency.
- Standardised battery form factors, allowing third-party compatibility.
- Self-healing materials for water seals, removing the repair vs. durability trade-off.
- Magnetic battery connectors that allow replacement without screws or adhesives.
If these technologies take off, the wearables of 2030 might not only track your blood oxygen and predict your workouts but also stay on your wrist for a decade without becoming e-waste.
Conclusion: A Smarter, Longer-Lived Future
In 2025, wearables are evolving from disposable gadgets into durable companions. The rise of repairable wearables with replaceable batteries is more than just a design trend—it’s a response to growing consumer awareness, regulatory shifts, and environmental urgency. As buyers demand devices that last, manufacturers will have no choice but to prioritise longevity alongside innovation.
The next time you shop for a smartwatch or fitness tracker, remember this: a device that dies when its first battery dies isn’t truly “smart”. Repairability isn’t just good for the planet—it’s good for your wallet, your convenience, and your peace of mind. The wearables of tomorrow aren’t just designed to track your health—they’re being designed to stay healthy themselves.
