Hawking radiation shrinks the black holes the faster the smaller they are. For microscopic black holes they evaporate in fractions of second, but a black hole the mass of our sun would evaporate in 10^67 years which is significantly more than the age of universe. So I think the chance to detect a big black hole that evaporated significant percent of its mass is zero.
