The average telephone uses 4.5-11 watts of energy a day. 0.5 is barely anything, flip phones maybe used that much 20 years ago.

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!

.5? The article said 100 microwatts so .0001 watts.

So wayyy worse than that.
