One of the major concerns about smartphones is their short battery life. With an increased number of apps running, GPS navigation and constant web browsing and video, juicing up frequently can be time consuming and frustrating. But a California teen has developed a device that can recharge cellphone batteries in just 20 seconds.

Eesha Khare, an 18-year-old from Saratoga earned the Intel Foundation’s Young Scientist Award for her invention of a small chip that can fits inside a cellphone and can charge the device in just 20 to 30 seconds.


She called the device a supercapacitor, an energy storage device that can hold a lot of energy in a small amount of volume. This small device ensures long battery life and also packs more energy into a smaller space than traditional phone batteries.

Khare, pocketed the $50,000 prize Young Scientist Award from the Intel International Science and Engineering Fair in Phoenix, Arizona, for this revolutionary device.

Khare is working on nano-chemistry, so that she can reduce the size of her invention.

According to her, the device is flexible, so it can be useful in rollup displays and clothing and fabric.

Well, Google has approached this teen to explore her idea about increasing the cellphone battery life.
