It has happened several times ... The publication is a bit old, but if someone else happens, I will comment ...
You they think it would be best suited if the battery was exhausted, the plug should show that this loading ...
This does not happen, and partly by the battery and Android ...
What to do??...
1) Leave the Nexus 4 connected to power about 1 hour (only Please assure that something has caught a current) ...
2) Press the power button, and NOT solteis until the LED (notification, the bottom of the screen) turn "Red" a couple of times ...
3) Let go button, and the battery on screen will appear, and appear to just this loading ...
4) Let the Nexus 4 load ...
With this I think you can solve your problem ... To me it has happened to me many times ... The first time it scared me to recarajo, but today is normal (should not be normal) ...
