Battery Low [Q] Bothersome Battery Calibration Issues?

I just Came from cyanogenmod 11 Android 4.4 KitKat and I flashed over TommyTarts' Quantum 4.4.2 KitKat on my Galaxy S3. I am using Zerolemon's 7500 milliamp battery and used to get 36+ hours of battery life. When I switched to Quantum, the battery charges to 100%, then immediately after I unplug the phone from the charger it goes straight down to about 57%. Is it a calibration issue or what?

Thanks in Advance
