Abstract
A device may enter a first active state associated with a device, exit the first active state and entering a sleep state associated with the device when user input is not received within a inactivity period, receive a first user input at the device during the sleep state, measure an elapsed time between a start of the sleep state and the first user input, and increase the inactivity period of the device when the elapsed time is less than a particular threshold.
Claims20
A method comprising:
- entering a first active state associated with a device;
- exiting the first active state and entering a sleep state associated with the device when no user input is received within an inactivity period associated with the device;
- receiving, after a first elapsed time, a first user input at the device during the sleep state;
- exiting the sleep state and entering a second active state, based on the first user input;
- exiting the second active state and re-entering the sleep state when no user input is received within the inactivity period;
- receiving, after a second elapsed time, a second user input at the device during the sleep state;
- and
- adjusting the inactivity period of the device when each of the first elapsed time and the second elapsed time is outside a time interval between a first threshold and a second threshold.
A device comprising:
- an input component to receive user input;
- an output component;
- and
- a processor to:
- enter a sleep state following an inactivity period associated with each of a number of active states in which power is delivered to the output component;
- decrease the power delivered to the output component in the sleep state;
- receive user input during the sleep state;
- determine an amount of time between a start of the sleep state and the user input;
- determine, for successive ones of the number of active states, that the amount of time between the start of the sleep state and the user input is shorter than a first threshold value or longer than a second threshold value;
- and
- enter another active state, subsequent to the successive ones of the number of active states, corresponding to a particular inactivity period that differs from an inactivity period corresponding to a previous active state with respect to the successive ones of the number of active states.
A computer-readable medium including computer-executable instructions, the computer-executable instructions including instructions, that, when executed on one or more devices of a mobile communication device, cause the mobile communication device to:
- enter a first active state associated with the mobile communication device;
- enter, from the first active state, a sleep state associated with the mobile communication device when the mobile communication device does not receive user input within a first inactivity period associated with the first active state;
- receive, after a first elapsed time, a first user input at the mobile communication device during the sleep state;
- enter, from the sleep state, a second active state associated with the mobile communication device, based on the first user input;
- re-enter, from the second active state, the sleep state when no user input is received at the mobile communication device within the first inactivity period;
- receive, after a second elapsed time, a second user input at the mobile communication device during the sleep state;
- determine that each of the first elapsed time and the second elapsed time is outside a time interval between a first threshold and a second threshold;
- and
- enter, from the sleep state, a third active state associated with the mobile communication device, corresponding to a second inactivity period, wherein the first and second inactivity periods differ.
