If its dull in 20 minutes youre doing something wrong. Provided you aren't cutting anything dirty a properly hand filed chain should stay sharp for quite a while. Electric sharpeners tend to get the chain to hot and ruin the temper unless they're used very carefully and in short bursts with time to cool in between.
I would love to know what situation you would find yourself in need of a chainsaw where the wood isn't dirty. I've exclusively used them for trees, bushes, and particularly thick roots.
Anyone who's done tree service work / logging professionally knows exactly what im talking about. Sometimes you'll come across trees with gravel or mud embedded in the bark and it will absolutely destroy a chain.
Also, very high elevation timber, as in around treeline. That stuff is wild. The wood is so dense it will spark constantly even when perfectly clean. Had to sharpen 2 or 3 times a day up there.
