An operating system 112 may determine an operational state for a computing device 110. The operating system 112 may assign a synchronization allotment 304 to the application module 114 based on the operational state. A synchronization engine 116 of the application module 114 may implement a synchronization scheme 306 based on the synchronization allotment 304. ## Claims ### Claim 1 A method implemented by a computing device having a display screen and a processor executing instructions to provide an operating system, comprising: determining an operational state of the computing device using the operating system, the operational state representing an amount of synchronization resources available at the computing device based on a combination of one or more of a power state describing a source of power provided to the computing device, a screen state describing a brightness level of the display screen, a network state describing connectivity type of the computing device to a data network, or a processing state describing usage of a processing power of the computing device;
