For the “activation” of cell phone battery,many claim that: first three of charging must last more than 12 hours in order to “activate” the cell phone battery. This statement is subjected to the previous nickel-metal hydride battery mechanism and it may mislead the users. For the latest technology of battery manufacturing, the cell phone battery have been “activated” during the manufacturing stage in which users are not required to activate it, as well as charging for more than 12 hours. Follow the instruction as written in the users manual is always the right choice of charging your cell phone battery. 

Besides, Phone with Li battery or charger will not perform charging after the battery is fully charged, which is different from the “trickle charge” of Nickel-battery charger. In other word, charging is in vain after your Li-battery is fully charged. No one can ensure the long-lasting of the discharge protection circuit features and quality of the battery, so your battery will always be classified as in dangerous state. This is another reason for us to disagree of prolonged charging time for your Li battery.
