Lithium ion batteries tend to have longer life and better performance over that life if they are topped off. There are too many variables to say what the user is going to see exactly under the user's conditions of use. You need to use the device the way you need to. But to get the most you can get out of the battery, avoid high and low temperature exptremes (don't freeze and don't leave in a hot car) and charge the battery when you have the opportunity. Avoid letting the battery get to the point the indicator turns yellow or red, if you can. Charging at night when you sleep, every night, would be a good first step.
