Insanely rapid battery drain
Hey guys, my nexus out of the blue started to rapidly deplete its battery. My charge will go from 100%-0 within 2 hours with the screen OFF. Yep, a total screen on uptime of about 13 seconds. I hoped the problem was with the battery itself so I bought a replacement 3800mah extended battery and it's still having the same problem, except now it'll drain in about 4 hours with the screen off.
I tried all the things I could find via search, turning off all syncs and settings I could but nothing improved it. Also I've wiped several times, there's no additional apps installed or anything, just stock. The phone seems to charge normally, taking about the same time as when it worked fine to get to 100%.
I'm guessing it's a hardware issue, but I'm out of warranty on the phone. Any of you experience something similar and was able to replace a part manually, or is my phone prettty much a brick.
