I got the gnex the day it came out and don't usually let my battery below 25%. Well night I actually went down to 6% after listening to music and doing some face booking. Well after a few minutes, I checked my phone again and it went up to 7%. Didn't think much of it but then checked again after a few minutes and it went up to 9%. Thought it was weird and then about 30 minutes after my phone said 6%, my phone said 10%. I have never seen my battery increase overtime. As I am typing this, I have actually went down to 9%. Wonder if anyone else has seen this before. Maybe I will never have to charge again!!!
