Basic Features
Equipped with 850 / 1800 / 1900 GSM frequencies, the T630 is set to go
wherever you go, whether in Asia, North America, or Europe. With a slightly
more powerful 770 mAh Li-Polymer battery (compared to the T610's 750 mAh),
users will be able to talk longer.
Sony Ericsson rated the T637 at 315 hours of standby and 14 hours of
talk time. The significance of the 770 mAh battery, however, is not exactly
clear since both standby and talk times were rated exactly the same. But
in real-world tests, the T630 yielded slightly better results although still
virtually the same as the T610.
Standby Time: 285 hours
Talk Time: 8.5 hours
The T630 uses Sony Ericsson's well known 5-way joystick to navigate menus
or turns through games. The same popular joystick has been found on the
T610 as well as the T68i. It is considerably more resourceful than a 4-way
directional keypad, allowing navigation and gaming without lifting the thumb.
Slight changes were also made to the keypad. The buttons are larger resulting
in easier use. Larger buttons also mean, however, that the keys run into
each other. So for those with sloppy fingers, misdials are more common on
the T630.
Screen
When the T610 was first released, it was at the forefront of display
technology. Within the year, however, 65K colors became relatively mainstream.
With high-end phones using TFT screens, more vivid displays and faster
refresh rates are possible. Sony Ericsson has decided to upgrade the T630
with an improved TFT screen rather than the T610's STN screen. The most
notable difference is the visibility of the screen in sunlight. Whereas
the T610 was difficult to read in direct sunlight, the T630 is brighter
and clearer.
STN screens have ghosting and residual artifacts from previous screens
due to slow refresh rates. The benefit of TFT screens comes from placing
the transistors directly on the surface resulting in considerably faster
refresh rates. STN screens were decent for phones that didn't require high
performance displays. However, with the advent of more advanced cell phone
gaming, such as the Nokia N-Gage, more graphically intensive multimedia
content require faster response times.
Audio
 The
T630 has the ability to play up to 32 instruments simultaneously. A few
ringtones come preinstalled on the phone; more can be obtained through WAP
or transferring via data cable, infrared, or Bluetooth. Also included in
the software is Music DJ, an advanced ringtone composer. By using a library
of pre-stored instruments, rhythms, and melodies, Music DJ allows users
to compose their own unique ringtones, all in a matter of minutes.
With MP3 playback becoming more mainstream, it is surprising that Sony
Ericsson did not add a built-in player. However users that must have music
can spend a few extra dollars and purchase the Bluetooth Music Handsfree
HBM-30 accessory. It features a digital music player capable of playing
MP3 and ATRAC3 audio files. The HBM-30 also includes an expansion slot in
the form of Sony's proprietary Memory Stick Duo.
