Abstract

A method for transferring data between a mobile device and a client includes sending transactions from the mobile device to the client over a first connection and determining how often to receive new data.

sending, in response to instructions from a processor, application data requests from a mobile device to a host over a first connection at a first frequency;

receiving data from the host responsive to the sent application data requests;

selecting a power management mode, from a plurality of power management modes, based on an amount of battery power remaining on the mobile device, wherein selecting a power management mode is further based on the amount of battery power remaining being below a predetermined amount;

changing the frequency that the application data requests are sent from the first frequency to a second frequency associated with the selected power management mode;

wherein at least two of the power management modes are a low power mode configured to conserve the amount of battery power remaining on the mobile device and a normal operation mode,

wherein the normal operation mode is configured to allow the mobile device to send application data requests more frequently than when the mobile device is in low power mode,

wherein the frequency at which some application data requests are sent is not changed to the second frequency while the mobile device is in the low power mode; and

exiting the low power mode when an amount of battery power remaining is above a predetermined amount.

2. The method of claim 1, further comprising:

receiving a trigger that notifies the mobile device of new data; and

receiving new data from the host,

wherein receiving the new data from the host is at least in part responsive to the trigger,

wherein the new data is of a type for which a trigger is to be sent, and

wherein the trigger causes the mobile device to send at least one data request associated with the trigger.

3. The method of claim 1, wherein the predetermined amount is 75% of battery charge.

4. The method of claim 1, wherein the mobile device sends application data requests periodically.

5. The method of claim 1, further comprising authenticating a user of the mobile device over the first connection, wherein authenticating a user is performed by sending an authentication token.

6. The method of claim 1, further comprising authenticating a user of the mobile device by sending an authentication token over the first connection, wherein the authentication token is verified against a user database.

7. The method of claim 6, wherein authenticating the user allows the mobile device to access content at the host.

8. The method of claim 1, further comprising receiving a notification of new content.

9. The method of claim 8, wherein the notification is received over a connection that is maintained while the mobile device is in the power management mode.

10. The method of claim 8, wherein the notification includes a portion of a content that is to be received by the mobile device.

11. The method of claim 8, wherein the notification includes less than a totality of the content to be received by the mobile device.

12. The method of claim 8, further comprising establishing a subsequent connection for receipt of the content.

13. The method of claim 8, wherein the notification includes an identification of a sender of the content.

14. The method of claim 8, further comprising displaying the notification on the mobile device for viewing by the user.

15. A mobile device located in a mobile network, comprising:

a battery;

a processor configured to allow the mobile device to;

send application data requests to a host over a first connection at a first frequency;

receive data from the network responsive to the sent application data requests;

select a power management mode from a plurality of power management modes based on an amount of battery power remaining on the mobile device, wherein the selection of a power management mode is further based on the amount of battery power remaining being below a predetermined amount;

change the frequency that application data requests are sent from the first frequency to a second frequency associated with the selected power management mode;

wherein at least two of the power management modes are a low power mode configured to conserve the amount of battery power remaining on the mobile device and a normal operation mode,

wherein the normal operation mode is configured to allow the mobile device to send application data requests more frequently than when the mobile device is in the low power mode,

wherein the frequency at which some application data requests are sent is not changed to the second frequency while the mobile device is in the low power mode; and

exit the low power mode when an amount of battery power remaining is above a predetermined amount.

16. The mobile device of claim 15, wherein at least one of the power management modes uses charge gradient levels for determining how often to send application data requests.

17. The mobile device of claim 15, wherein at least one of the power management modes is configured to allow the mobile device to send application data requests less frequently on weekends than on weekdays.

18. The mobile device of claim 15, wherein the processor is further configured to allow the mobile device to:

receive a trigger that notifies the mobile device of new data; and

receive the new data from the host,

wherein receiving the new data from the host is at least in part responsive to the trigger, and wherein the trigger is received by the mobile device when the new data is of a type for which a trigger should be sent, wherein the trigger causes the mobile device to send at least one data request associated with the trigger.

19. The mobile device of claim 15, wherein the predetermined amount is 75% of battery charge.

20. The mobile device of claim 15, wherein the sent application data requests occur at a first frequency when the mobile device is in a normal operation mode, and at a second frequency when the mobile device is in the low power mode, wherein the first frequency is higher than the second frequency.
