Remember predictive texting? It was a huge improvement from the multi-tap approach. Mobile phones have come a long way since then and advancements in the industry are not slowing down.

Power

Battery life is one area of mobile that seems to have taken a backwards step, as function-packed phones require more power. The days of charging a Nokia 3310 on a weekly basis are long gone, with phones today working harder than ever before. With continuous use, the average phone lasts 9 hours 48 minutes, and takes around two hours to fully charge.

What if you could charge a battery in five minutes? Graphene Flagship partners Thales and M-SOLV, together with researchers from IIT, Italy, are currently in the process of making this a reality, taking full advantage of one unique material — graphene. The highly conductive properties of graphene have enabled the companies to develop high power graphene supercapacitors. These are to be used in the aeronautical and space sector, providing the industries with energy storage devices that charge and discharge at high speed. As these devices charge much faster than conventional batteries, this development may also benefit the mobile industry, enabling smartphones to become fully charged in just minutes.

In the future, phones could also be charged over-the-air. This is a step up from wireless charging pads, with a company called Energous developing this technology. If a phone is within three feet of the transmitter, it will start charging automatically. As this technology improves, and charging distances inevitably get bigger, phones may be kept constantly charged without the need for worry or wires.

Phone case technology is also complementing these efforts. The NanoCase for the latest iPhones contains a graphene panel that dissipates excess heat inside the phone quickly. The developers claim this extends the battery life by up to 20 per cent.

Some manufacturing using these heat dissipating properties in phones as part of its super cooling systems. This keeps the phone cool, even while being pushed to usage limits.
