Well, I was just getting started with my OG Motorola Droid with the 4.1 jelly bean mod. I got stuck trying to get apps2sd to work (and still probably can't manage to get it to work). Then all of a sudden, my battery went to 1% - died, but then I went to charge it. Then from that point on, it basically just gave out. My phone gave crazy readings - like one moment, 5%. (Power off) Next, 50%. (Power off) Next, 1%. (Power off) Next, 80%. Eventually, it (the phone) stopped working Unless I put it on the charger. Tried to do the battery in the freezer trick. The phone actually claimed that it was completely charged.........until I took it off the charger..and it died.. Some how some way, I managed to get $3 bucks for free online, and bought a new battery (thank God)...But then it hit me..What if it's my phone that's the problem and not the battery? I swear, I'd be so upset if that were the case..Lol..Is there any way that I could find out which is exactly the problem? The only real hint that I have is that when I had set my phone back to it's Original rom, the battery icon had a question mark symbol in it. The prongs on the inside seem completely okay as well. Yet, I still don't completely know whether it's my phone or the battery itself..
