To clear this up - EACH time you charge your phone's battery, it
shortens the life span, no matter if it's Li-ion or the antiquated Ni-CD.
As a rule of thumb, the initial charge is the most important - charge to
manufacturer's instructions (normally more than 10 hours) with the phone
off. After that charge when the battery is almost flat. Do so for about
4-6 hours.
