Man stranded in mountains saved by broken Nokia

A 70-year-old Taiwanese man trapped in a ravine for five days without food was rescued thanks to the long battery life of his old cell phone, news portal chinanews.com reported.

A total 250 police officers were involved in the extensive four-day search for the man surnamed Liu after he fell over the edge of a path along a mountain in Taichung, Taiwan.

Although the phone was broken during his fall, police were able to approximate Liu's position by tracking the signal emitting from his decade-old Nokia handset.

Remarkably, his trusty phone held a charge for the five days it took officers to reach him.

Rescuers zeroed in on Liu's location by calling his number and listening for his ringtone.

"My old phone saved my life," said Liu.
