150 Ampere

Nokia has applied for a patent on a triple slider phone. The entire device is a three-layer deal. The drawings show a candy bar type phone that slides up, down and to the right. The right slide, which is the bottom layer of the device, reveals a QWERTY keyboard. The mid-layer upslide reveals function and control keys, while the downslide reveals a numeric keypad.

Depending upon the engineering, the two slide layers could allow a user to use the slide functions and the keyboard simultaneously. It seems somewhat unwieldy, since the keyboard and the control pads would be at 90 degrees from each other. The design is an extension of the company’s N95 device.

The triple slider is a long way from being in the consumer’s hands, but if you want to take a look at Nokia’s current lineup, swing by TestFreaks and take a look at what Nokia’s got. While you’re there, you can read the expert reviews on all of Nokia’s phones.
