Assuming a constant current flow of 360 ma out,

2900 mah / 360 ma = 8.05 h

Just over 8 hours

Unless the 360 ma is divided up among the number of batteries being charged.

It depends how much you use the handset. If it's just on 'stand-by' - it'll probably last a few days/ If you're listening to music, watching video etc... about 6 hours.
