The present invention relates to a battery saving method for a portable terminal and a device for the same. The present invention includes a step of measuring and comparing time required to arrive at a predetermined destination and battery life time when a navigation application of the portable terminal is executed and a step of performing a power saving mode function when the battery life time is less than the time required to arrive as a result of the comparison. The present invention can increase time in which the navigation application can be operated. [Reference numerals] (201) Execute a navigation application; (203) Set a destination; (205) Battery available time [A] and time [B] required to the destination to arrive; (209) Perform the directing in a power saving mode; (211,215) Arrive at the destination?; (213) Perform the directing in a normal mode; (AA) Start; (BB) End
