Battery Life for Playback of music

[ltn]

I was wondering if anyone knows how long the iphone 3g last by just playing music the entire time. BTW I am assuming you can use bluetooth headsets to listen to music, Correct?

Looking at the tech specs page for the iPhone 3G, it says:

Audio playback: Up to 24 hours

With the current OS (2.2.1) you cannot play music over bluetooth headsets. However, OS (3.0) is coming out soon and it will allow you to do just that (Stereo Bluetooth). Music playback is 24 hours but it can vary depending on things such as signal strength, signal type (3G,Edge), email fetching or pushing, etc.

That 24 hours probably isn't very accurate now if you own mostly iTunes Plus-format songs. Since the files are twice as big, they take more juice to run. I can't give any stats on actual battery life, but that's just how it works. Doubling the size of songs also makes an 8GB phone a helluva lot smaller than it was a year ago.
