Power Saving method for mobile communication terminal

A power saving method for a mobile communication terminal, comprising:

• determining an activation condition setting for a user function;
• detecting whether the activation condition is satisfied;
• measuring a remaining power capacity of a battery if the activation condition is satisfied;
• determining whether the remaining power capacity of the battery is smaller than a prescribed reference value;
• and
• storing in a memory said activation condition setting if the remaining power capacity of the battery is smaller than the prescribed reference value, and de-activating the corresponding user function.

A mobile communication terminal, comprising:

• means for controlling a plurality of user functions;
• means for detecting a remaining power capacity of a battery;
• means for automatically deactivating at least one of the plurality of user functions in accordance with the remaining power capacity of the battery;
• and
• means for automatically reactivating the at least one deactivated user function.

An improved mobile communication terminal, wherein the improvement comprises:

• configuring a mobile station modem to determine whether a remaining power capacity of a battery is below a prescribed reference value;
• configuring the mobile station modem to store a current setting of a prescribed active user function in a memory if the remaining power capacity of the battery is below the prescribed reference value;
• and
• configuring the mobile station modem to automatically deactivate the prescribed active user function if the remaining power capacity of the battery is below the prescribed reference value.

A mobile communication terminal, comprising:

• a mobile station modem configured to control at least one prescribed user function;
• and
• a battery coupled to the mobile station modem to provide power to the mobile communication terminal;
• wherein the mobile station modem is configured to detect a power reserve condition of the battery and deactivate the at least one prescribed user function if the power reserve condition of the battery falls below a prescribed threshold.
