Abstract: In a method for controlling a fast dormancy function of a mobile device, the method detects whether the mobile device is in an operating mode or in an idle mode. When the mobile device is in the operating mode, the fast dormancy function of the mobile device is disabled. When the mobile device is in the idle mode, the method determines whether one or more data packets are transmitted between a base station and the mobile device. When one or more data packets are transmitted between the mobile device and the base station, the fast dormancy function of the mobile device is enabled after a predetermined time interval.

Abstract: An electronic device for digital notebook includes a display unit, a touching unit, a processing unit and a storage unit. The display unit displays a digital notebook which includes an edited area in a predetermined area. The touching unit receives a touch signal. The processing unit increases the size of the edited area based on a proportion from an original size to a first size according to the touch signal, and compresses the size of the edited area from the first size to the original size, that is, a first resolution corresponding to the first size will be decreased to a second resolution corresponding to the original size. The storage unit stores the digital notebook according to a storing signal. The display unit displays the note content of the digital notebook corresponding to the original size after storing.

Abstract: In a method for managing packet transmission using an electronic device, a refreshed application sends refreshed packets to a wireless base station is determined when the electronic device is in a connected state with the wireless base station. When the electronic device receives a disconnection signal, the method determined whether the disconnection signal is a result of a disconnection operation performed by a user on the electronic device. When the disconnection signal is not the result of the disconnection operation, the method further controls the electronic device to attempt to reconnect to the wireless base station and not to send any disconnection information to the refreshed application within a predetermined time period, when the electronic device does not receive any communication signal.
