The handset The next step might be to decide on the type of handset you favour. Handsets come in different configurations, from the 'candybar' format (long and slim) that is able to fit into a protective carrying case and be operated by one hand. The screen and keypad are limited by the size and shape of the handset. Flip-phones and slider phones have the advantage of small size, but their screens and keypads can be larger because of the use of two halves of a 'clamshell' case. Some slider phones have keypads on a swivel, offering a two handed operation. A smartphone has a fully functional keypad that enables the editing of Microsoft word documents, presentations and spreadsheets.
Screens and memory Colour screens are now standard in most models, but size, resolution and colours can vary, from between 101x80 pixels to 353x288 pixels; and between 4000 and 262,000 colours. The better the screen resolution, the better backgrounds and graphic images can be displayed. Mobile phones also now have onboard memories from between 16MB and 96MB (although this is a standard that changes quickly). Additional memory (500MB or more) is available on phones dedicated to gaming and mp3 playing, and some phones also offer slots for adding additional memory cards.
Battery and camera Battery re-charge life of a phone is determined by the number of features and the amount of talk time used, but today's phones range between 10 and 14 days of standby time and 2 to 8 hours of talk time. Obviously memory intensive use shortens the re-charge time. Even the most basic phones now come with an in-built digital camera. Some now also have flash capacity, auto-focus, self-timing, continuous shooting and zoom and macro facilities. Many offer low-resolution video recording and can be used for video conferencing and receiving streaming video. Optimally, a camera with more than one mega pixel is desirable.
