Battery Calibration issue

Could someone kindly point me to the area of know-how for an issue im having with my battery. After flashing many roms and restoring many backups, my phone is losing battery faster than ever without any services running. I have used a battery calibration app to assist in my issue but to no avail. It will drain very fast but lose ZERO percents over night and even gain 4 to 5 percent while the screen is off for extended time. THis led me to believe my battery is out of whack and needs some TLC pls help b0ss
