You're conflating Watt-hours and Watts. Watts are a measure of power, which is energy consumption per unit time. Watt-hour is power multiplied by time, the time cancels and so it's a measure of energy. 0.5 Watts for an entire day adds up to 12 Watt-hours in a day, which is a reasonable estimate for a phone battery.

My bad! You’re right!
I always hated electrical engineering and it was by far my worst subject. Sorry for not being very knowledgeable with it, thanks for the correction!
