Following the helpful posts and hints I have found, I never use fast chargers and try to keep the battery of my Onyx Boox Note 2 with a charge between 40% minimum and 80% maximum.

Often when I have to add to a book or other task,I let the device charge
a little bit normally, and always without exceeding 80% max (battery charged).
Are these small loads beneficial or detrimental to the battery?
Thank's a lot in advance
