Default Excessive battery drain...

Dear All,

My N5 draws excessive battery when in standby mode (screen off). It usually ranges from 300-400mA per hour. I was usually getting only 2-10 mA on my N4. I installed the same apps on my N5 that I used on my N4. I'm not a sure if Google Search is constantly on. I disabled Google Now, Google Play Books,Google Play Magazines, Google Play Music, Google Hangouts, Google Newsstand. I'm using Battery Monitor Widget by 3C and 2X Battery - Battery Saver. The Battery Monitor to keep track of the discharge amounts. I am still getting 3.5-4.0 SOT though. Any ideas for common excessive battery drain on Kit Kat 4.4 / N5?
