You must be on KitKat...
Just a Note. CM is great, but for me battery life on it was not so great compared to Stock. If you use bluetooth, there seems to be a bug on bluetooth, it drains your battery. That was still active about a week ago. You can switch off Bluetooth when you do not use it, it will improve the battery life.
I also got three days the biginning of the week on stock KitKat. Which is great and by stock I mean LG Firnware. Just wish I can fix the ugly dropdown they have on their firmware.
BTW this is my opninion don't throw bricks
