Body
The size of the phone in format (H x L x W) and the volume of the phone where available.
If the phone has a flip, it is measured with the flip closed.

Display
There are lot of display types used in mobile phones. They can be either color or monochrome. Monochrome displays on the other hand can be alphanumeric or graphic. Alphanumeric displays can show only symbols with a constant size, while graphic displays can show fonts of different sizes and animations.

The color displays usually are CSTN, TFT, TFD or OLED with a predominant use of TFT displays in current mobile lineups. There are also two types of touchscreen displays - capacitive and resistive, which are both based on TFT technology.

Camera
Some phones feature a camera that gives them the ability to work as a digital camera. Often (though not always) the camera is also able to shoot video.

The most important characteristics of a camera are the resolution (measured in megapixels), lens focus type (either fixed or automatic) and the presence of a flash. The flash could be either LED (single or even double) or xenon.

The number of megapixels is not always a good measurement of the quality of the photos, but if you plan to print pictures, you would generally get higher quality ones out of higher megapixel cameras.

Auto focus lens are not a guarantee of better image quality, but fixed focus cameras are usually inferior. Most importantly, only auto focus cameras can allow shooting of really close objects - i.e. macro shooting.

Some phones offer optical zoom but those are rare. Most use digital zoom, which degrades the quality of the photo.

Cameras that can work in "video mode" are characterized by the maximum resolution and framerate (frames per second or fps) of the recorded video.
