Per use, yes but the overall life cycle and ability to hold maximum charge will degrade.
That said, for replaceable batteries, that is not a concern and I do the same as you. For non replaceable, not fully charging / discharging will aid in keeping capacity longer.

This is a modern myth that has carried over from the days of NiCd and NiMh batteries (when it was indeed relevant). Lithium ion batteries do not have any memory effect. Even more so, like kierenlon said, deep discharging lithium ion batteries actually reduces the overall lifespan of them.

Here is some reference information:

https://www.newark.com/pdfs/techarticles/tektronix/LIBMG.pdf

This document indicates that full charge and discharge provides a battery lifetime about the same as partial (topping off after every use). From the linked article, "The typical estimated life of a Lithium-Ion battery is about two to three years or 300 to 500 charge cycles, whichever occurs first. One charge cycle is a period of use from fully charged, to fully discharged, and fully recharged again. Use a two to three year life expectancy for batteries that do not run through complete charge cycles."

Here is another link:

Since there are so many articles available on the internet, it is difficult to see a consensus on how to keep them viable for the greatest amount of time,  so please make your own conclusions.
