A self-attaching supplemental battery for a cellular phone comprises a housing containing a rechargeable battery. A releasable attachment pad is affixed to an attachment side of the housing to releasably couple the housing and the rechargeable battery to a back of the cellular phone. A cover is removably carried by the housing, and selectively locatable on either side. The cover comprises a panel sized and shaped to cover the releasable attachment pad in a protection location when located on the attachment side of the housing, and to expose the releasable attachment pad in a storage location when located on the face side of the housing.

A method of efficient pocket detection is proposed. A wireless device determines whether it is in a transition state by using a plurality of low power-consuming sensors. The wireless device powers on a high power-consuming sensor if the device is in the transition state, or otherwise keeps the high power-consuming sensor off if the device is not in the transition state. The wireless device detects a current pocket mode of the device using the high power-consuming sensor if the device is in the transition state, or otherwise keeps a previous pocket mode if the device is not in the transition state.

In a communication control method for a communication terminal device including a plurality of communication units corresponding to different communication schemes or communication systems to perform communication in parallel, when a first communication unit performs transmission, transmission/reception of another communication unit is stopped. Then, a transmission/reception stop duration of the another communication unit is set to be equal to or less than a predetermined number of synchronization protection stages.

Disclosed are a mobile terminal capable of implementing an always-on function with a lower power, based on a motion, and a motion-based low power implementing method thereof. The method includes sensing a motion of a user by using an acceleration sensor in a low-power always-on that only the acceleration sensor is activated; a selectively activating an always-on function according to the sensed motion and deactivating the always-on function when no motion is sensed in an always-on state and automatically entering to the low-power always-on function.

A resource statistics collection method and apparatus, and a terminal are provided. The method includes: recording a process running on a terminal at each of at least two time points; for each of the time points, obtaining at least one hardware resource invoked by the process running at the time point; obtaining a process set including processes running at the at least two time points; and obtaining, according to the hardware resource invoked by the process in the process set, information about the at least one hardware resource occupied by an application associated with the process in the process set.
