Any chance that the AirTag could have a software memory leak that would normally be masked by cutting power once a year? Its possible right? The code must be written in something low level like C.

Would be kinda funny if 10 years from now the author gets his stuff stolen again and then discovers said memory leak crashed the Airtag 9 years ago. As Elon Musk likes to say: "The most ironic outcome is the most likely" . (OP I hope your stuff does not get stolen again, its just a joke)

That's a very good point. The system design of the airtags assumed a much shorter battery life, which may have led to decisions that would introduce issues at 10x battery life. Thinking more like overflow issues. But could also be a complete non-issue. Hard to say.

Given the resources on the device (it's a Nordic nRF52832 with 64 KB RAM), I'd expect any memory leaks or similar defects to show up well before a year.
