Abstract

A handheld device and a power saving method are provided. The handheld device comprises a transceiver and a processor electrically connected to the transceiver. The processor executes a sync procedure every a sync period to enable the transceiver to establish an internet connection with a mail server to receive a mail data, determine that the handheld device works in an idle mode, and automatically adjust the sync period by extending the sync period gradually.

Claims

1. A handheld device comprising:

a transceiver; and

a processor, electrically connected to the transceiver, being configured to execute a sync procedure every a sync period to enable the transceiver to establish an internet connection with a mail server to receive a mail data, determine that the handheld device works in an idle mode, and automatically adjust the sync period by extending the sync period.

2. The handheld device as claimed in claim 1, wherein the processor adjusts the sync period by extending the sync period in a plurality of stages.

3. The handheld device as claimed in claim 2, further comprising an input module electrically connected to the processor, wherein the input module generates a user input signal and the processor receives the user input signal from the input module and sets the sync period of each of the stages according to the user input signal.

4. The handheld device as claimed in claim 3, wherein the input module is one of a touch panel and a keyboard.

5. The handheld device as claimed in claim 1, wherein the processor sets the sync period to 15 minutes in the beginning and doubles the sync period every time the processor execute the sync procedure until the sync period is extended to 4 hours.

6. The handheld device as claimed in claim 1, wherein the processor further decides a minimum sync period according to an execution of a mail application on the handheld device, and sets the sync period to the minimum sync period in the beginning.

7. A power saving control method for use in a handheld device, the handheld device comprising a transceiver and a processor electrically connected to the transceiver, the power saving control method being executed by the processor and comprising the following steps of:

(a) executing a sync procedure every a sync period to enable the transceiver to establish an internet connection with a mail server to receive a mail data;

(b) determining that the handheld device works in an idle mode; and

(c) automatically adjusting the sync period by extending the sync period.

8. The power saving control method as claimed in claim 7, wherein the step (c) is adjusting the sync period by extending the sync period in a plurality of stages.

9. The power saving control method as claimed in claim 8, wherein handheld device further comprise an input module electrically connected to the processor, the input module generates a user input signal, and the power saving control method further comprises the following steps:

receiving the user input signal from the input module; and

setting the sync period of each of the stages according to the input signal.

10. The power saving control method as claimed in claim 9, wherein the input module is one of a touch panel and a keyboard.

11. The power saving control method as claimed in claim 7, wherein the step (c) is setting the sync period to 15 minutes in the beginning and doubling the sync period every time executing the sync procedure until the sync period is extended to 4 hours.

12. The power saving control method as claimed in claim 7, further comprising the following steps:

deciding a minimum sync period according to an execution of a mail application on the handheld device; and

setting the sync period to the minimum sync period in the beginning.
