It's neither particularly useful nor harmful.


The battery will stop charging when it reaches 100%, and resume charging when it loses 1 or 2% charge.


There is nothing wrong with leaving it charged or disconnecting it when it reaches 100%. It's entirely up to you, and what is convenient for you.


I leave it connected over night to charge, and may ver may not disconnect it during the day, I depending on wether I need to take it somewhere or not.
