2018 MacBook Pro Battery Life issues

i have a macbook pro 2018 and my battery life is terrible. It was advertised as having 10 hours of battery life and i only get roughly 4 hours of battery life. The only app i use is google chrome so i dont understand why my battery life is so bad. I checked battery health information and it shows condition as normal. Is anyone getting 10 hour battery life? what am i doing wrong?
