battery draining issue in c9 pro

[pydiharsha123]

Dear Team

I have charged my phone with 100 percent today morning by 8.30 am. Now the time is 1.22 pm . battery has come down from 100 to 68 within 3.5 hrs time.
also attached the battery usage screenshot.

I am facing this issue after upgrading to nougat O.S
since this phone is equipped with 4000 mah battery. I expect at least the battery to run for 24hrs.
so where is the problem team? pls answer
