Abstract

The present disclosure relates to a method for power management of an electronic device, the method comprising determining an onset of a predefined time segment corresponding to a time period; obtaining power consumption data by monitoring at least one of a current power consumption rate, a current device state, and a current device usage pattern of the device during the predefined time segment; selecting a power consumption category for the predefined time segment based on the power consumption data; switching from a first power saving mode active on the device to a second power saving mode based on the selected power consumption category; and performing one or more operations on the device based on the second power saving mode.

First claim

The invention claimed is:

1. A method for power management of a device, the method comprising:
determining an onset of a predefined time segment corresponding to a time period;
obtaining power consumption data by monitoring at least one of a current power consumption rate, a current device state, and a current device usage pattern of the device during the predefined time segment;
selecting a power consumption category for the predefined time segment based on the power consumption data;
switching from a first power saving mode active on the device to a second power saving mode based on the selected power consumption category; and
performing one or more operations of controlling a reception of a notification from one or more other devices communicatively coupled with the device, or controlling an activation of one or more sensors associated with the device, on the device based on the second power saving mode.

2. The method of claim 1 , wherein the determining the onset of the predefined time segment comprises:
determining the onset of the predefined time segment corresponding to the time period based on a current time.

3. The method of claim 1 , wherein the switching from the first power saving mode active on the device to the second power saving mode further based on a current screen-state of the device.

4. The method of claim 1 , wherein the time period is at least one of a year, a half of a year, a quarter of a year, a month, a week, and a day and the predefined time segment is adjusted based on the time period.

5. The method of claim 1 , wherein the one or more operations further comprises at least one of:
controlling a screen brightness of the device by a predefined value;
controlling a duration for switching to screen-off state by a predefined value;
clearing at least a portion of a memory of the device;
terminating one or more background applications; and
controlling network access for one or more applications.

6. The method of claim 1 , wherein the current power consumption rate corresponds to a rate of battery percentage drop, the current device state corresponds to at least one of a power-on-state, a power-off-state, a screen-on-state, a screen-off-state, a charging state, and a discharging state of the device, and the device usage pattern corresponds to usage information of the device collected based on at least one of a user action and a user preference.

7. The method of claim 1 , further comprising:
performing a set of actions on the device based on the monitoring.

8. The method of claim 7 , wherein the set of actions comprises:
detecting current available power based on the current power consumption rate;
detecting available power for a next time segment of the time period based on the current available power; and
generating a notification indicative of the detected available power on the device.

9. The method of claim 7 , wherein the set of actions comprises:
detecting a current power consumption category for the predefined time segment based on at least one of the current power consumption rate, the current device state, and the current device usage pattern of the device monitored upon an expiration of the predefined time segment;
deriving a second power consumption category for the predefined time segment of a next time period based on the current power consumption category;
updating power consumption data with the second power consumption category; and
sharing the updated power consumption data with a second device.

10. The method of claim 7 , wherein the set of actions comprises:
determining an action to be performed on the device at a next time segment of the time period;
obtaining a second power consumption category for the next time segment based on the power consumption data;
generating a notification on the device based on at least one of the action, the second power consumption category, and a current available power of the device.

11. The method of claim 10 , wherein the set of actions further comprises:
identifying a second device for performing the action;
comparing the second power consumption category for the next time segment and a third power consumption category of the second device for the next time segment; and
performing one or more additional operations based on the comparison.

12. The method of claim 1 , further comprising:
detecting a real-time event on the device;
selecting a second power consumption category for the time segment on a second device based on power consumption data associated with the second device;
performing one or more additional operations based on the second power consumption category and the power consumption category.

13. The method of claim 12 , wherein the real-time event comprises at least one of a user input of initiating a communication with the second device, a user input of sharing one or more data with the second device, and an incoming call from the second device.

14. The method of claim 1 , further comprising:
obtaining a power consumption mapping data by mapping a plurality of the selected power consumption categories to a plurality of time segments for the time period.

15. An apparatus for power management, the apparatus comprising:
a display;
a detecting unit configured to monitor at least one of a current power consumption rate, a current device state, and a current device usage pattern of the apparatus during a predefined time segment; and
at least one processor configured to:
determine an onset of the predefined time segment corresponding to a time period,
obtain power consumption data by monitoring performed by the detecting unit,
select a power consumption category for the predefined time segment based on the power consumption data,
switch from a first power saving mode to a second power saving mode based on the selected power consumption category, and
perform one or more operations of controlling a reception of a notification from one or more other devices communicatively coupled with the device, or controlling an activation of one or more sensors associated with the device, on the device based on the second power saving mode.
