    I just want to make a device that detects if my phone is fully charged and then turns off . How can I make this?.. Its just like a smart adaptor for phone's charger. Any Advice?

    The phone itself will stop "charging" its battery at the right time. Why another device?

    Read about lithium batteries. The charger circuit must detect a full charge then shut off.
    The "charger" for your phone is simply a dumb power supply for the smart charging circuit that is inside your phone.
