Philips X550: One-Month Standby Time?!

[Sialac]

Ok, one month is a long time, but does anyone know how long this phone's talk time is? In any case, specs look pretty good, except for the lack of WiFi:

-QVGA display with 262k colors
-Bluetooth
-FM radio with RDS
-3.2MP autofocus camera
-MicroSD card support, up to 8GB
-112 x 45 x 11.7 mm

I think the total talk time is more or less "normal", so I dunno why anyone would get this phone for its eternal standby... for isolated communities perhaps?
