    Guess this Galaxy J7 of mine is getting old. Charged it Monday night and when I woke up it was only at 46% So I put it on the charger and used it for a couple hours and it was at 31% What the heck? Isn't the percentage supposed to go up instead of down? Something isn't right.

    Welcome to Android Central! Using a phone while charging can still make the battery level drop -- it depends on what you're doing with the phone, how fast the charging is, and how old the battery is. But overall, I'd suspect a failing battery -- you could try replacing it.
