Abstract
A battery driven device including a rechargeable battery; and a processor to detect a first voltage of the battery at first time and a second voltage of the battery at second time following the first time; calculate a difference between the first voltage and the second voltage; compare the calculated difference with a first threshold of a voltage change; compare the second voltage with a second threshold; change a setting of the battery driven device so as to increase power consumption when the second voltage is larger than the second threshold. The setting of the battery driven device may be maintained when the second voltage is less than the second threshold.
Claims1
A battery driven device, comprising:
- a rechargeable battery;
- and
- a processor configured to:
- detect a first voltage of the battery at first time and a second voltage of the battery at second time following the first time;
- calculate a difference between the first voltage and the second voltage;
- compare the calculated difference with a first threshold of a voltage change;
- compare the second voltage with a second threshold;
- change a setting of the battery driven device so as to increase power consumption when the second voltage is larger than the second threshold;
- and
- maintain the setting of the battery driven device when the second voltage is less than the second threshold.
