Why do you think this? It takes about six months to burn through a fob battery, and we’ve only had the releases for a little over a month. I do not recall seeing a post here or in Lucid release notes that would indicate battery live is changed. Can you point to posts or other releases to back that up?
I don’t think the fob vs. car is settled science. There are a couple anecdotal cases that may indicate fob, but they are not universal. I think it is more likely a both-and situation, that the car and fob may be over-communicating through a highly complex protocol that both burns battery and causes unreliability. If it was simple, Lucid would have solved it a year ago. Fobs are highly mature technology.
