Thank you both for your replies. Now that I think of it, it does look like it's not taking up water, because it's the leaf tips that turn brown/yellow, as if water isn't reaching them. But I am leery of repotting it because it's what started this whole thing. When I repotted it back in 2015, it lost 5 leaves right away, and has lost another 3-4 at a slow but steady drip since then. If I do repot it in a smaller pot, what kind of soil should I use? What should I look for in the roots? From memory I remember its root system was very small. I also noticed the aspidistra turns its soil into almost concrete after a few months. This is the original reason I repotted it.
Would feeding it help boost leaf growth? I have never fed the plant, and it puts out 1-2 new leaves every growing season (which I think is normal for aspidistras). If I should feed it, should I wait till next growing season (it has never put out new leaves this late in the year)?
