Hi Hooria. Are you always connected to the internet? It's probably those apps that uses the internet that drains your battery. I suggest that you force stop them if not used. Also turn off the internet (Wi-Fi or mobile data), Bluetooth, NFC when not in used to save battery. Also, lower the brightness and screen timeout to maximize your battery.
