As the wearable market grows increasingly competitive, transparency regarding software longevity has become a focal point for consumers. For owners of the Amazfit T-Rex 3 and several other popular Zepp Health devices, a significant milestone is approaching. New data suggests that the software lifecycle for these rugged devices could reach its final chapter by late 2026.
Defining the End-of-Life (EOL) Roadmap
Recent documentation from Zepp Health’s official support index has shed light on the specific “Security Update EOL” dates for its current lineup. Unlike smartphones, which often have publicized multi-year guarantees, smartwatch support can sometimes feel ambiguous.
For the Amazfit T-Rex 3, the current projected deadline for security patches is September 2026. This date marks the point where the manufacturer is no longer legally or operationally obligated to provide the critical security layers that protect user data and device integrity.
Which Devices Are Affected?
The T-Rex 3 isn’t the only model facing a potential sunset. The support roadmap indicates a rolling expiration for several core products:
-
Amazfit T-Rex 3: Security support is slated to conclude in September 2026.
-
Amazfit Balance: Early iterations of this health-focused watch are seeing their “Security EOL” windows arrive as early as late 2025 or early 2026.
-
Legacy Models: Older “Pro” variants and the Bip series are also moving toward the “EOL Product List,” a category where Zepp Health explicitly states it no longer maintains firmware or software updates.
The Distinction Between Security and Features
Users need to distinguish between security updates and feature updates. While a device reaching its security EOL will stop receiving vulnerability patches, it doesn’t necessarily mean the watch will stop functioning or receiving minor “Zepp Flow” or app-side optimizations immediately.
However, historically, once security support ends, major OS overhauls and new fitness metrics—like the recently released BioCharge or advanced HYROX tracking—typically cease. For those who purchase a T-Rex 3 in mid-2026, this could mean entering a “frozen” ecosystem just months after unboxing the device.
A New Standard for 2025 and Beyond
Recognizing the demand for longer-lasting tech, Amazfit has hinted at a shift in policy for its newest releases. Moving forward from June 2025, several upcoming models are expected to receive a minimum of three years of updates.
A few exceptions already exist:
-
The Active 2 NFC is scheduled for support through June 2028.
-
The Amazfit Up headphones are rumored to have an even longer four-year support window.
What This Means for Consumers
For current T-Rex 3 owners, the watch remains a powerhouse of outdoor navigation and biometric tracking today. However, if you are a buyer who prioritizes long-term software relevance, the 2026 cutoff is a critical factor to weigh. As the industry moves toward 2026, the focus for Zepp Health appears to be shifting toward its next generation of “Pro” hardware and AI-integrated ecosystems, leaving current models with a clear expiration date on the horizon.
