Alright, I know that my G1 has a MP3 player but can the battery honestly last if you listen to music on it?.. I mean I only use my phone for phone calls and text messaging and I can run the battery down to about 20% on the daily.. My question is for the people that actually listen to music on their phone. Doesn't it completely kill your phone when you listen to music?.. Or do you have to carry your charger around everywhere with you to preserve it?.. P.S. What's the word on these new batteries from T-Mobile?
