Battery
Talk time:The total time a battery can power a device for calls. As the device drains the battery during a call, the talktime left in the battery is diminished until the device is turned off or the battery recharged. The longer the talktime the less frequently you will need to recharge. Talktime, expressed in hours and minutes, is much shorter than standby time because transmission requires more power.

Design
Backlight display:A backlight is a form of illumination used in liquid crystal displays (LCDs). As LCDs do not produce light themselves - unlike for example Cathode ray tube (CRT) displays - they need illumination (ambient light or a special light source) to produce a visible image. Backlights are used in small displays to increase readability in low light conditions such as in watches, and in computer displays and LCD televisions to produce light in a manner similar to a CRT display.
Display resolution:The number of distinct pixels in each dimension that can be displayed. It is usually quoted as width × height, with the units in pixels: for example, "1024 × 768" means the width is 1024 pixels and the height is 768 pixels. The higher the number of pixels, the sharper the image.
