when new, most microwave ovens give the rated power output (the best models give a slightly higher than stated output) but this quickly reduces a little (when the best then give their rated power)
over time the output steadily declines with usage, taking longer to cook.... it will get to 1/2 original power if used long enough but they normally die well before this.
the oven uses a device called a magnetron or wave generator which is similar in design to an old radio valve (its the basis of radar units) and they slowly (very slowly) burn out.
