Techniques for generating schedule(s) specific to a merchant for managing power states of component(s) of a point-of-sale (POS) system of the merchant are described. Transaction data associated with transactions involving the merchant may be received from a POS application of the POS system. Based at least partly on the transaction data, a schedule for managing the power states of a component, such as a battery-operated payment reader device, may be determined. The schedule may indicate when to change a first power state of the component to a second power state. The schedule may be sent to a POS system. The POS system may use the schedule to manage the power states of a component of the POS system, such as a battery-operated reader device. Additionally, or alternatively, the POS system may determine triggering events and may manage the power states of the component based on the triggering events.
