Resistivities p(T) of ceramic samples of Lal.825Sr0.175CuO 4 (LSCO) and both ceramic and single-crystalline (a-b plane, containing micro-twins) samples of YBa2Cu307 (YBCO) were measured from Tc to 1100K. The observed absence of saturation in the linear parts of p(T) implies weak electron-phonon coup
