Or Nexus issue... As I do every night I plugged in the Nexus next to my bed (it was at about 35%) and went to sleep. As I do every morning I picked it up and hit the power butting to see what was going on. Today however when I hit the power button - nothing - nada. I tried holding it down - nothing. Dead. Keep in mind this is the extended battery and yes the charger was working and plugged in. I unplugged it and tried it - nothing. I removed the battery and put it back in - nothing. So I went to the other room, grabbed my original battery and put it in. It instantly booted up no problem at 95%. I decided to try to extended again. I took out the original and put in the extended and it came right up. Keep in mind I didn't say "booted up", literally it just worked as if I had not swapped batteries. I pulled it and put it back in again and still it didn't boot up it just came on. (like a hot swap) The one wildcard here is that I kept the phone plugged in the entire time except when trying to get the extended working after a pull. Now I have the extended in and it's working fine. And when I did finally get the extended to boot the battery symbol came up first as empty and then a second later as full. Defective Nexus, Battery, or just bug?
