By generalizing the dimensionless skill, we investigate the quasinormal modes and thermodynamics analytically for three types of regular black holes. The deviations of the first law and Bekenstein bound are shown. Meanwhile, we verify that the second phase transition and Davies points still exist in regular black holes. In addition, we calculate the quasinormal modes of these black holes in the eikonal limit by applying the light ring/quasinormal mode correspondence, and discuss their spiral-like shapes and the relations between the quasinormal modes and thermodynamics of black holes.
