I do not know the wattage of the speakers in a phone, but I suspect it 
can be near 1 W, because that's the power of a traditional small 
speaker. However, phone speakers are far cousins of standard speakers. 
They produce an amazing volume with amazing reliability for something 
that small.

I guess the result of the experiment varies with the volume of the 
speaker. Was the user close to the speaker?
