    My phone begins charging at 1000mA, according to the 'Charging Current' app.
    After about 10 minutes or so, it begins dropping, and eventually reaches 100mA.
    It charges fast as the start, as expected, but the charging slows down as the current drops, as expected.
    I have tried a different battery and tried another phone's charger (One that can only support 700mA) And so it starts at it's max (700mA) And drops to about 200-300mA.
    My concern is this magical drop that is occuring. Everything seems to work fine otherwise.
    Any ideas what's causing this?




    EDIT: Also, this doesn't happen if I let my phone be. (I have to plug it in, and no do anything on it while it charges)
    if I begin using any app for a minute or two, the drops begin. And they do not come back up!

    Welcome to Android Central! I believe it's normal for current to fall as any rechargeable battery's charge level rises. But you're saying that if you leave it alone, it will remain at the original current until it reaches 100%?

    Yes, I have to specifically leave it alone as soon as I plug it in.
    Examples to make this clear:
    I begin charging it, I leave it alone. The current will remain a constant 1000mA till full charge.
    I begin charging it, I start using apps. The current will drop to an extremely low 100mA AND will remain so until I plug it out and in again.
    I'd be okay with it if it went back to it's original 1000mA current as soon as I lock the phone. But it doesn't, so in that case it will pretty much never charge as the current remains so low (100mA)

    That's puzzling. This probably won't help, but it won't hurt either--do a cache partition wipe: http://forums.androidcentral.com/sam...2-s3-tab2.html

    Get rid of the charging app. All it does is provide you with something else to worry about.

    That's not how you handle problems...
    The only reason I got that app is to confirm my theory, because I noticed the phone wouldn't charge (It would just stall when plugged it, basically cancelling out usage just barely)
    And I'll be sure to do that, B.Diddy.

    It's actually related to temperature. It starts at max and drops to the safe level quickly to not damage the battery. It's nothing wrong with the charger or cable. If it was cooler it would stay at max forever. Keep it cool ❄❄;-)
