It seems like there is an issue with the shield or with the firmware if it has any, or maybe it does not have the functionality that i was expecting.
So first issue that i saw is if you connect the photon to the headers and put the battery the photon rgb led has a light dim red colour and nothing happens, you remove the battery and connect it back the photon starts to work.
Second issue, i put the usb on the power shield to charge, the led is blue and the battery goes to 100 % then if i leave it like this connected all the time, the red status led gets on and the battery starts to discharge like there is no usb connected, i just leave it like this and the battery still gets lower and lower so that means that somehow the photon gets powered by the battery part and not by the usb part.
The idea was , as long as there is power connected to the board to use that and once power is missing to go to the battery like a small ups. but it seems that it`s not like that .
if i disconnect the power supply, leave it little bit and reconnect it , it starts to charge again and the cycle repeats itself. i did not tried to flat the battery to see if the charging part starts automatically after a certain level or not.
please let me know if this is a bug or if it is normal.
