With more and more options available to today’s users it is no wonder that phones are beginning to get a little larger in order to hold all that information. One study took a closer look at the inner workings of three such cell phones to really see what makes them tick. The three cell phones in question were the FOMA P905i VIERA, the au W53H, and the Softbank 920SH AQUOS.

The first things that the researchers noticed upon opening up these cell phones were that the internal layout was quite neat and organized. The manufacturers has not strung cables and wired across the interior of the handsets in order to pack in more options. Instead, they have kept everything neat and tidy. It was also evident that everyone is working very hard at each manufacturer to cut power usage.

In the W53H the antenna had been completely internalized, a very desirable, not to mention useful, feature of a handset that expects to make progress in today’s market. With this cell phones as well as the 920SH, thinness of design has been their goal and they have been working very hard to achieve it. Three techniques have been utilized by the manufacturers in order to get a thinner look: component layout upon the main board, the structure of the keyboard, and the shape of the battery.

For the P905i, one of the key features that the researchers noticed was the double opening mechanism that allowed the handset to open in two directions. First, it can be opened in the traditional vertical direction, but it can also be opened horizontally.

The main circuit board of the W53H is packed full of features. The sub board is used to hold the microSD card slot, the LED flash as well as other features that the cell phone boasts. Along with the OLED panel, this cell phones also features a completely internalized antenna as well. Actually, the antenna is made up of three parts: a tunable antenna, a metal plate antenna and a board pattern antenna.
