I don't know what to say... because I am not sure what helped for battery drain in SE.
As someone mentioned I turned off and on location services and did force restart (both hold power and restart till Apple logo appear ).
Results for today (32% left - I am sorry for Polish language here but you will figure out what is what ):
Wifi + 5h on LTE / 2G (when had bad coverage) [mostly 2-3 bars]
Offline podcasts, one mail fetch every 15 mins (thanks Apple and Google for Gmail on native app ).
Far the best usage I had ever... ok almost no phone calls but had a short iMessage talk and downloaded few updates via WiFi...
