A team of electrical engineers at the University of Illinois, USA, has found a way to extend the battery life of mobile phones and laptops significantly, allowing them to operate many times longer than current devices after a full charge.
To achieve this, the research team focused on transforming digital memory devices, as they are the biggest consumers of power.

The temporary memory of mobile devices contains a thin metal wire, through which electricity flows to access data when needed. Therefore, reducing the size of this metal wire leads to lower power consumption. The researchers replaced the metal wire with carbon nanotubes, which are 10,000 times smaller than a human hair, allowing memory bits to be retrieved faster while consuming less power.
Professor Eric Pop, the leader of the research team, stated that this breakthrough will enable users to plug their mobile devices into a charger overnight and use them for weeks or even months. His team is also exploring ways to charge mobile devices using thermal energy, kinetic energy, and solar energy. (According to Telegraph)
