Sony Ericsson Z800

In open mode, the Z800i offers a bright and clear 262K colour display with a resolution of 176 x 220 pixels. Its keypad provides low audible noise and the navigation keys are comfortable in use, but unfortunately, horizontal edges separating the rows of the numeric keypad cause a feeling of inresponsiveness. The same key layout is used for three shortcut buttons placed just above the numeric keys, activating the video telephony application, the main menu and the music player.
The user interface of the Z800i is of the same caliber as that which is found in the Sony Ericsson K750i, being both slick and user-friendly with regard to navigation in menus and text input. The video telephony application also turned out be very easy in use, providing a simple yet well-working interface. Still, it should be noted that despite this technological prowess, few handset as of yet offer such capabilities as compared to the total pool of phones in users' hands.
Z800i's integrated 1.3 megapixel camera only performed average, producing acceptable pictures in daylight and poor pictures under poorly lit conditions. White balance and crispness particularly suffered as compared to the image quality of the Sony Ericsson S700i. On a more positive note, the handset's music player performed very well, both in terms of audio quality and user interface. New playlists can be created and an equalizer provides the ability to optimize sound, but as with the K750i, the Z800i doesn't provide an integrated 3.5 mm jack but rather relies on a dongle - which must be purchased separately. We would certainly also have appreciated an integrated FM radio.
With regard to connectivity options, the Z800i sports tri-band GSM/GPRS 900/1800/1900 MHz, as well as WCDMA 2100 MHz, Bluetooth, Infrared and a mini-USB Type B port. A Memory Stick Duo expansion slot is also available, backed up by a 64 MB Memory Stick storage card and an USB cable providing an easy means to transfer MP3 files to the phone. The Z800 also features 7 MB of non-volatile internal memory, polyphonic and MP3 ringtones, SMS and MMS, instant messaging and e-mail, and lastly Java MIDP 2.0 as well as WAP 2.0 support.
Reception and voice quality for the Sony Ericsson Z800i both proved excellent, while its battery offered approximately 5 hours of talktime and 5 days of standby time as compared to the claimed 10 hours of talktime and 10 days of standby time operating on a GSM network. As for video telephony, our test maxed out at one hour as opposed to the claimed one and a half.
