Best Answer

Le GPS d’un téléphone portable peut continuer à fonctionner même lorsque la batterie est épuisée, mais seulement dans certaines conditions.

Le GPS est un système de positionnement qui utilise des signaux émis par des satellites pour déterminer l’emplacement d’un appareil. Les signaux GPS sont captés par une antenne GPS intégrée dans le téléphone portable, qui est généralement distincte de l’antenne utilisée pour la communication sans fil.

Lorsque la batterie d’un téléphone portable est épuisée, cela signifie que l’alimentation électrique qui alimente le processeur et les autres composants du téléphone est interrompue. Cependant, si le téléphone portable dispose d’une fonction de localisation par GPS, l’antenne GPS peut continuer à fonctionner pendant un certain temps même après que la batterie est épuisée, à condition que l’appareil soit suffisamment proche d’un satellite

Cela dit, la durée pendant laquelle le GPS peut fonctionner sans alimentation de la batterie dépend de divers facteurs, tels que la qualité de l’antenne GPS, la force du signal satellite et la température environnante. En général, la durée de fonctionnement est assez limitée et il est recommandé de ne pas compter sur la fonction de localisation par GPS d’un téléphone portable épuisé pour des situations critiques ou d’urgence.

No. The computer-like insides of a GPS receiver need a small amount of current to operate.
