    Default overcharging?

    Is it possible to overcharge the battery? I usually charge mine overnight and I'm worried of the extra hours I'm charging it while I sleep...

    I don't believe that there is any cause for alarm. I turn mine off each night to charge my phone. I also have a charger in the office where it charges when not in the holster. I also have a car charger to charge whenever I am in the car. The I have done this with all my smartphones.

    Most modern battery charging does not continue charging when the battery is full. I assume that is the case with the S3.

    My evidence is that when I unplug my phone from the charger in the morning, it usually drops immediately to 98 or 99%, which is where I assume it stopped charging.

    i recalibrated my s3's battery indicator as i realised that when it was showing 100%, it took an extra 20mins to be actualy fully charged. cant remember what app i used but if you search "battery calibration" or something u should find one. "over-charging" only damages the environment

    I have seen the same thing. After checking email in the morning I will put it back on the charger while taking a shower. When I pull it back off the battery will show 100% for a longer time and last a bit longer. From my understanding, what happens is that once the battery hits 100% the charger begins to cycle off and on usually with a range of 2%+/-. This explains what we are seeing. After using the phone for a few minutes, topping it off to 100% helps give it a little extra boost.

    No worries, OP with charging. Plug it in and let it go.

    Are you spamming us and selling this. The phone prevents over charging. This would be annoying.

    So far, i have not heard anybody actually representing any cell phone companys.
    We have not heard of anybody representing any battery companies at all.

    I have been to 2 Cell Phone providers in my area, and both have told me that the Samsung
    Cellphones are *NOT* smart chargers.

    Remember, companys often 'Out Source' other companies to make/design their equipment
    for them.

    It's not the charger that's smart, it's the phone which regulates the charge. If the battery were getting overcharged, it would get very hot just sitting there once the charger hits 100%. Have you noticed that happening?

    But if it makes you feel better, there's certainly no harm in unplugging the phone when it reaches 100%.
    PLEASE, when asking for help provide as much information as possible. We can't help unless we know what the symptoms are and what you did before they began.
