Huge battery drain :(

Hi, i just bought a note 3 neo, imported sealed set. It runs on android 4.4.2, but the battery drain is too much. So i factory reset, and it went back to 4.3, the battery was better, but actually, even better is really bad. When running 4.3, i realized that screen took the most battery power, and i could only have around less than 2 hours of screen time, with full battery. So i updated it using odin, back to 4.4.2, and factory reset, but battery problems still occur. I included the links of images of my battery status, running android 4.4.2
