This application discloses a measurement method and apparatus, and a device. The method includes: the terminal device divides all neighbors detected on a same measurement frequency into at least two measurement groups, and performs RRM measurement separately on the at least two measurement groups based on an RRM measurement parameter corresponding to each measurement group, where the at least two measurement groups are in a one-to-one correspondence with at least two RRM measurement parameters, and the terminal device has different power consumption when performing RRM measurement on the at least two measurement groups based on the corresponding RRM measurement parameters.
