what is the % power thats left if i drop a ball of m = 1 kg from the height of h = 1 m at earths gravity g = 9.82 ms/s. and the same values except h = 0.54 m

It's not clear to me exactly what you are after, but:
Potential energy is given by: PE = mgh
Kinetic energy is given by: KE = (1/2)mv^2 where v is velocity
PE + KE = constant
Also, note that power is rate of change of energy, so should your question really be expressed in terms of power?
