Had absolutely no problem with mine , with regards to working but I did manage to break the thin side of the upper section when removing it , as it's quite weak.

As far as I remember the red light indicates charging and the green fully charged. The one I had only worked a couple of times before the connectors became loose and didn't work at all. Sent it back and got a refund. Poor quality product in my opinion.

It does charge it back up and once charged you can remove it from the phone. If I use my phone from 8.45am I get to 20% by 3/4pm. I stick this on and it takes me past midnight but I leave the case on. It does act as a protector as well.
