Thank you so much. I have done everything you said and will write my experiences.@karatasmert34
After some troubleshooting i found some settings that improved battery performance to better than stock.
WI-FI settings -> Turn on Wi-Fi automaticcaly -> Set it to off
WI-FI settings -> Network rating provider -> Set it to None
Security & Location -> Location -> Advanced -> Scanning -> Turn off both Wi-Fi scanning and Bluetooth Scanning
Clear all data for Google Play Service and reboot
Hope that helps.
I would like to hear your experience.

Edit: I've used my phone for 1 day after I applied them and it worked magnificently. Normally I used to use %80 of battery in a day and today I used only %50 although I did the same things on the phone. Thanks again @kulight
