A radiotelephone (300) having timer shutoff feature and a roam shutoff feature. The timer shut off feature implements a process (102-114) in which a processor (310) determines (106) if a flip (408) is closed or an end key (410) has been pressed. If either of these events occur a timer is started (108). If the timer exceeds (110) a predetermined period of time before another phone call exists (112) the radiotelephone (300) is placed (114) in an off mode. The roam shutoff feature implements a process in which the processor (310) determines (116) if the radiotelephone (300) is in a roam mode. If the radiotelephone (300) is in a roam mode and no phone call exists (118) the radiotelephone is placed (114) in the off mode.

Method and apparatus for saving power in a radiotelephone

An electrical joint using spheroidal tipped leads improves the strength of a connection regardless of the material used to bond the connections. Axial leads of a component are formed into spheroids using an appropriate heat source to melt a small portion of the lead tip. Melting a portion of the lead alloys the lead with any non-wettable solder mask rendering a wettable spheroid. Surface tension in the molten metal forms the spheroid. The spheroid increases the area to which solder or other bonding agent adheres to. Solder mask remaining on the lead decreases solder wicking further up the lead. Reduced solder wicking retains the compliance of the lead. Controlled melting of the lead maintains planarity for multileaded components.
