    Overcharging the Battery?

    I've read that a smartphone owner has to have a completely different attitude toward phone charging -- that keeping the phone on the charger is a good idea for smartphones. Yet when my battery is fully charged, my "full battery" screen comes up and tells me to unplug the phone. Why? It's so much more convenient for me to leave the phone on the charger than realize the battery has drained just when I want to use it. Is there a reason why it's not a good idea to keep charging the phone when the battery is fully charged?

    li-ion batteries aren't going to over charge. I've always left my smart phones on the charger when full with no adverse effects

    I plug mine up at night and leave it on the charger until I am ready to leave for work. I just ignore the "battery fully charged" message cuz it usually alerts me that its fully charged in the middle of the night..... LOL I too have had no issues with this procedure.

    it says to unplug the charger because it conserves energy, has nothing to do with charging.
    your charger actually uses a very small amount of electricity when its not in use, hence its costing you money to have it plugged in, charging or not.

    the reason its ok to leave the charger connected is, when its full the battery stops charging and it will not charge again until you unplug/reconnect the charger or reboot the phone.

    Your phone will not let you overcharge. There is a circuit that stops charging and cycle you between 95% and 100%. That's why sometimes you are not at 100% when your phone has been on the charger and why 'bump' charging works.

    But with that said, I try to avoid keeping my phone on the charger. Li-Ions are happiest when they are charging or discharging. While not the best thing for your battery to sit on the charger the reality is many of us have to charge while we sleep and it will not harm your phone or battery.

    I've seen this a lot. What exactly is bump charging? Is that where you plug it in for a while but don't fully charge it? I actually do that quite a bit. I use my phone very heavily so I have chargers everywhere.

    sorry dont know
    my phone always charges to 100% when given adequate time.
    if it hits 100% while im using it, i will unplug/replug to get it charging again.
    i woke up today (not the first time) to 15% batt, phone said 100% until i pulled the charger out.
    7 hours of streaming while i was trying to sleep lol..... like i said, when its done its done, it wont start again
    until the charger plug is cycled....
