I have no idea if either battery has any charge at all at this point (though I suspect not). Taken the battery out, smacked it a few times, tried to charge with my computer, tried different cables/chargers, nothing helps. I've tried to let it charge for 30-45 minutes, but no change. Won't turn on in any mode, plugged in or not - I do get a flicker of the opening "Samsung Galaxy" screen before it shuts off and goes back to vibrating. It will continue to vibrate like that for a minute or two after I take it off the charger before it finally stops. Now, when I try to plug the phone in it just pulse-vibrates every 2 or so seconds instead of showing that it's charging. I tried to stop it, but it turned itself off and on probably 20 times before it finally totally died (kind of reminded me of how sometimes an sick animal will go bat guano bonkers before it kicks it). I quickly tried to turn the phone off to see if I could even get even a little bit of an efficient charge out of it, and the phone started power cycling. Instantaneously, though (I'm not exaggerating, it was literally instant), the phone dropped to a 1% charge. Knowing that battery was garbage (which is why I got a new one I just held onto the old one for emergencies), I put the phone on the charger and the battery icon showed charging. Put the battery in, the phone turned on and showed a 47% charge. I couldn't get it to do anything, so I tried an old battery that I had. However, by the time I woke up, the phone was dead, though still plugged in. It showed on the battery icon that it was charging, and the red charge indicator light was on once the display turned off. Last night, I plugged my phone in before bed.
