    should you keep your charger plugged in after phone is done charging?

    i've heard recently that nokia is working on better alerts to alert you that your cell phone is done charging so you will unplug it and save electricity. my question is this. after your phone is done charging and you unplug the phone, if you still have the charger wire plugged in the wall, does it still waste electricity? i think it does, but my brother says it dont. does anyone know for sure?

    it shouldn't waste anything since when the battery is full, the phone stops charging, now with it plugged in i am am pretty sure the phone runs off the a/c adapter not the battery

    Thats not exactly true. do this, plug in your phone to the charger. then remove the battery. if you notice the phone shuts off. After the phone is done charging is it goes into a "trickle charge" what this does is keeps the battery full as long as its on the charger. so theoretically its not wasting electricity. Its just keeping your battery fully charged.

    cus tickle charging still uses up charge cycles and doing it often will diminish your battery life.

    read the responses. it DOES consume electricity. it just trickle charges your phone to keep it full (if your phone is on, it still uses electricity after all)

    It does consume electricity. It's best to unplug a phone (or notebook PC) after it is charged rather than leave it plugged in.

    the transformer in the charger uses electricity whether or not your phone is plugged into the charger. that's why if everyone unplugged their chargers from the wall, instead of just their phones from their chargers, you could light a city with the saved electricity.

    unplug your chargers... or get a "smartstrip"

    A phone charger plugged into mains electricity and turned on with either a fully charged phone attached or even nothing attached will consume about £40 of electricity a year..

    the OP was asking if the charger consumes power even when the phone is NOT plugged into the charger. the topic concerns conservation, not battery health.

    Its my understanding, that the charger, regardless how much its rated at max supply, will only use what is drawn from it.

    I would say the charger being plugged in without a phone connected draws very little current.
