In the modern day era of the mobile phone market, it is perhaps unsurprising to see the inventor of the wireless mobile device claim that handsets have become too complex in recent years. The extended features in the latest mobiles with digital cameras, music software and GPRS equipment have made these products more than just an ordinary mobile phone.

It is a stark contrast to the design and lack of efficiency of the first ever wireless call made back in 1973. Former Motorola researcher, Martin Cooper played a significant role in its creation, as the lead engineer of the Motorola development team. Cooper appears concerned that by creating a multimedia device, it is impossible to appease everybody: "Whenever you create a universal device that does things for all people, it does not do any things well.

"Our future I think is a number of specialist devices that focus on one thing that will improve our lives."

This view does not appear to be endorsed by smartphone manufacturers that are churning out more and more handsets in the lead-up to the Christmas period. With over four billion people across the globe owning a mobile handset, there is an argument to suggest that a converged, multimedia device is more efficient for day-to-day use.

The impressive evolution of the efficiency of a mobile is a stark contrast to the initial model. Cooper said: "The first cell phone model weighed over one kilo and you could only talk for 20 minutes before the battery ran out, which is just as well because you would not be able to hold it up for much longer."

Modern day mobile phone batteries are designed to absorb multimedia usage and can now be used for hours on end. Nevertheless, for consumers on the move it is important to own a spare battery in the event of the primary battery draining. Mobile phone batteries and other accessories can crucially improve usage and maintain communication links.
