A wake-up control method and apparatus, and a terminal device are provided. The method includes determining, by a wake-up control apparatus, whether a network of a terminal device is in a connected state; and if the wake-up control apparatus determines that the network of the terminal device is not in the connected state, stopping, by the wake-up control apparatus, wake-up of the terminal device by N application wake-up timers, where N is an integer greater than or equal to 1. The wake-up control apparatus shields some application wake-up timers, such that the shielded application wake-up timers do not wake up the terminal device.
