I am now realizing I should have gone into more detail about the issue. I went to plug it in today, and it wouldn't charge. It was running the latest Milestone build of CM11. I went ahead and tried to turn it off and back on, and it started boot looping. I managed to get it into AP Fastboot and fastboot-flashed it back to stock. It has an unlocked bootloader. So now I'm on stock Android 4.1.1, and boot looping with the battery below ten percent. Above ten percent, it stops looping and just kind of sits there, but will boot up fine. Once I get it back into Android, it stops charging again. The issue persists no matter what cable/charger/PC combination I use. Since it charges fine in Fastboot, Recovery, and while off, and persists across multiple chargers and cords, the only idea I have is that it is a software issue in Android somewhere, I just can't figure out for the life of me where it might be.
