Is it possible to disable battery loading on a PC connection?
 

I connect and disconnect my phone often with my notebook and wonder if it will decrease the lifetime of the battery over time? It loads, stop loading, loads another % and stops again... that can't be healthy.

So is there a possibility to disable the "auto-load" when the N900 gets connected with a PC? Or maybe a button like "mass storage + load, mass storage only..."?
