Apparatus and methods for power management on mobile devices
View Patent ↗Various embodiments for providing enhanced power savings in mobile computing devices are described. In one or more embodiments, a mobile computing device may monitor the battery power level remaining. The mobile computing device may select a wireless connection type for an application based on Quality of Service (QoS) requirements of the application and the amount of battery power remaining. The mobile computing device may switch the application from a higher QoS wireless connection type to a lower QoS wireless connection type when the battery power falls below a threshold. Other embodiments are described and claimed.
1. An apparatus comprising:
a radio processor, to connect to at least one radio providing at least two wireless connection types, wherein a first wireless connection type consumes power at a different rate from a second wireless connection type;
a host processor, to operate an application that uses the radio;
a battery to supply power to the radio processor and the host processor; and
a power management component to:
select a wireless connection type for the application according to a Quality of Service (QoS) requirement of the application and an amount of power remaining in the battery,
monitor a battery power level, and
cause the application to change to a different wireless connection type having different QoS parameters when the battery power level falls below a threshold.
2. The apparatus of claim 1 , a wireless connection type comprising at least one of: a short range wireless connection, a wireless network connection, a global system for mobile communications (GSM) connection, a code division multiple access (CDMA) connection, or a wideband code division multiple access (WCDMA) connection.
3. The apparatus of claim 1 , the power management component to cause the application to terminate when the battery power level falls below a threshold.
4. The apparatus of claim 1 , the power management component to disable the wireless connection type when the battery power level falls below a threshold.
5. The apparatus of claim 1 , the radio processor to notify the power management component when the battery power level is too low to allow applications having certain QoS requirements to operate or to continue operating.
6. The apparatus of claim 1 , the power management component to prevent the application from operating if the battery power level is below a threshold.
7. A non-transitory machine-readable storage medium comprising instructions that, when executed, cause a mobile computing device to:
begin operating an application on the device to:
determine a QoS requirement of the application;
determine a battery power level on the device;
select a first wireless connection type for the application according to the QoS requirement of the application and the battery power level;
monitor a power level of the battery; and
cause the application to change to a second wireless connection type operating at a lower QoS than the first wireless connection type when the battery power level falls below a threshold.
8. The non-transitory storage medium of claim 7 , a wireless connection type comprising at least one of: a short range wireless connection, a wireless network connection, a global system for mobile communications (GSM) connection, a code division multiple access (CDMA) connection, or a wideband code division multiple access (WCDMA) connection.
9. The non-transitory storage medium of claim 7 , further comprising instructions that, when executed, cause the mobile computing device to:
cause the application to terminate when the battery power level falls below a threshold.
10. The non-transitory storage medium of claim 7 , further comprising instructions that, when executed, cause the mobile computing device to:
disable the wireless connection type when the power level falls below a threshold.
11. The non-transitory storage medium of claim 7 , further comprising instructions that, when executed, cause the mobile device to:
prevent the application from operating if the battery power level is below a threshold.
