Abstract
An electronic device is provided including a battery and a controller configured to: measure a present level of the battery; and adjust an operation of a hardware component of the electronic device based on the present level of the battery in order to maintain a reference battery level, wherein the reference battery level is associated with a specified time period in which the electronic device is required to remain operational.
Claims14
An electronic device comprising:
- a battery;
- and
- a controller configured to:
- measure a battery level at a first time point;
- compare the measured battery level with a reference battery level corresponding to the first time point;
- and
- restrict an operation of at least one resource of the electronic device based on the measured battery level if the measured battery level is smaller than the reference battery level corresponding to the first time point,
- wherein the reference battery level is determined to have different values over time to guarantee an operation of the electronic device during a time duration specified by a user input,
- wherein restricting the operation of the at least one resource comprises lowering a performance level of the resource or deactivating the at least one resource, and
- wherein the controller is configured to remove one or more restrictions placed on the operation of the resource in response to a specified time duration passing.

- restrict an operation of at least one resource of the electronic device based on the measured battery level if the measured battery level is smaller than the reference battery level corresponding to the first time point,
- wherein the reference battery level is determined to have different values over time to guarantee an operation of the electronic device during a time duration specified by a user input, and
- wherein the controller is configured to measure a battery level at a second time point while restricting the operation of the at least one resource, compare the measured battery level of the second time point with a reference battery level corresponding to the second time point, and remove one or more restrictions placed on the operation of the at least one resource if the measured battery level of the second time point is larger than or equal to the reference battery level corresponding to the second time point.

A method comprising:
- detecting an input specifying a time duration during which an electronic device is required to remain operational;
- measuring a battery level at a first time point;
- comparing the measured battery level with a reference battery level corresponding to the first time point;
- and
- based on the measured battery level, restricting an operation of at least one resource of the electronic device,
- wherein the reference battery level is determined to have different values over time to guarantee an operation of the electronic device during the time duration, and
- wherein restricting the operation of the at least one resource comprises lowering a performance level of the resource or deactivating the at least one resource,
- the method further comprising:
- removing one or more restrictions placed on the resource in response to a time period passing.
