Smartphone battery that last a week? Very soon, say scientists

British scientists claim to be on the cusp of invention with a new variant of 'smart glass' that can generate vibrant display from electrical pulses and save battery life so charging a phone becomes a once-a-week task.

Smartphone displays are like light bulbs. The more battery power you splash on them the brighter they shine. But what if you could use a bright screen they has nothing to do with the battery? This isn't just a fervent wish, for a team of British scientists claim to have developed a 'smart glass' that is like that.

Smartphone displays are guilty of consuming around 90 per cent of a phone's battery. And according to the scientists, if their 'smart glass' technology is implemented, our phones may last a lot longer than they currently do.

"You have to charge smartwatches every night. But if you had a smartwatch or smart glass that didn’t need much power, you could recharge it just once a week,” says Dr Peiman Hosseini, an Oxford University researcher.

The new 'smart glass' generates vibrant displays from electrical pulses and can look bright under sunlight as well. However, a prototype is under development and a commercial version may take longer to appear.

As per Dr Hosseini, the technology can also be used to develop smart windows in future which will be able to block infra-red waves to keep room cooler and negate the use of energy-intensive air conditioners to save up to 20 per cent of energy cost. It can also be used to create unfake-able holograms that will kill off counterfeit products for good.
