Examples described herein include systems and methods for reducing power consumption among multiple user devices that are communicatively coupled to a management server. The management server can receive an indication that a first user device (a laptop computer, for example) is in an active state and that a first application (an email application or a web browser, for example), is executing at the laptop computer. The management server determines that a second user device (a smartphone, for example) is associated with the same user and further determines that a second application is installed on the smartphone. The management server can determine that the smartphone is in an inactive state or that the second application is currently not executing on the smartphone. The management server sends an instruction to the smartphone to turn off at least one functionality so as to reduce power consumption.
