How Long Is a New Fire TV Stick Actually Supposed to Last?

Amazon does not set a fixed physical lifespan for Fire TV Sticks.

Security updates are guaranteed for at least four years after purchase or until the model’s published support date, whichever is later.

A Fire TV Stick may remain usable beyond that window, but slow performance, app or service compatibility issues, storage limits, and newer video standards can justify replacement.

Upgrade based on persistent problems rather than age alone, including support changes affecting services such as Netflix or newer models like the Fire TV Stick 4K Select and 4K Plus.
