Mobile phone battery life is one of the most important factors to consider when buying a phone. And Philips has one that will last a long tme with the Philips X550. This phone apparently has a battery that can last up to a month in stand-by. Some sacrifices had to be made obviously.

No 3G connectivity here and it relies only on GPRS and EDGE for data transfers. Some other features are: A QVGA display with 262k colors, Bluetooth, FM radio with RDS, 3.2MP autofocus camera, MicroSD card support and up to 8GB memory. No pricing info yet.

If subscription music services are for you, check out Napster, who is about to cut their price to $60 per year and let you keep a handful of tracks forever to boot. Beginning tonight, Napster will launch its new $5 per month deal that gives subscribers unlimited, on-demand streaming access to Napster’s library of music. That’s 7 million tracks from major and independent publishers.

Best Buy’s music service will even let you keep up to five unrestricted “CD quality” MP3 tracks every month. Pretty sweet deal.
