ok, so this just happened today and I don't know why. I have my phone plugged in and it will pop up all of a sudden with fully charged, ok fine. so I unplug it. then, a minute later, it all of a sudden says 50 percent battery. so I plugged it back in... and a minute later it says 100 percent again. then, when I unplugged it, it said 48 percent charged. ??? why is this happeniing? any fixes? this is, by the way, my second phone- the first was classified doa, and replaced... I have only a few days left in my 30 days... eta- on battery info, it now says: battery status- full, battery level 43, and this is while on ac plug.
