I've searched the forum and I have just found that people have problem when WiFi is off and battery drain like is on but that's not problem here.
To diagnose this you would need an app that monitors what it is that is draining the battery.
Try installing "Better Battery Stats," open the app once then close it. For a few hours, use your phone like normal or in a situation you want to diagnose. Then go into Better Battery Stats and post a screenshot of "Kernel Wakelocks," "Partial Wakelocks," and "Other" here so we can take a look.

Other apps which are good to see what is draining the battery are GSam Battery Monitor and Wakelock Detector.

Wakelock Detector: https://play.google.com/store/apps/d...kelockdetector
Do the same with these apps as I said with Better Battery Stats and post screenshots from them.
