Battery range dropping fast

[Whereitis]

I bought a 2014 i3 Rex last summer with 55k miles on it. When I first got it, it would show 60 miles available on a full (overnight) charge. A couple of months later it started showing 55 miles. Now it's 5 months later, I go out to the car and it shows 47 miles with a full charge. The car only has about 58k on it now. Has anyone seen the HV battery lose its capacity so fast? I'm concerned this means the battery is about to die.

Assuming you're in the Northern hemisphere, it's approaching the coldest time of year. It's normal to see the range drop in winter. ~20% is typical but (of course) varies depending on the temperature conditions where you are.

Well, it's gone from 70s and 80s down to 40s and 50s, so I suppose that could be it. I hope it doesn't drop much further when temps get down to below freezing.

There are other factors - one being the difference in driving style between you and the previous owner. If (for example) the previous owner only travelled slowly on city roads and you use high-speed roads, the guessometer would take a while to adapt to the new "normal", so you would expect that to correct after the first few drives in your ownership - it would not be immediate - though I concede that the process should take a matter of days or weeks - not months!
