The battery life for the Sony Ericsson W580i is as follows

Talk Time: 9 hours

Standby Time: 370 hours

Of course, the minute you start using the phone these times reduce ... but generally the W580i has a great battery life and is very reliable when fully charged.

This phone has uses the same type of battery as mine's and I get about 3 days before having to charge again. If you use it for music or make a lot of calls you'll probably only get a day or two out of it though.

I've never had this phone myself, but I have a friend who works at Carphone Warehouse whi has said that you're supposed to get about 9 hours of talk time out of it.
