I just got an android phone coming over from wm7.5. One of my primary uses of my phone is to listen to podcasts while I commute and work. I download all of my podcasts at home over wifi and I begin the day with a fully charged phone. In my experience with wm7.5, I make it easily through an entire day listening to podcasts anywhere from 3-4 h sometimes, I can still make it through the day listening to 10 h of podcasts but I sometimes have to charge it up in the early evening.
I'm on day one of my nexus S and am using doubletwist to listen to podcasts. My battery has drained ~10% in an 45 minutes and doubletwist is the main culprit for drainage (45%) followed by media server (26%). At this rate, I won't make it through the day. Is this others typical experience for using their phone as an mp3 player? Are there other apps that are less demanding on the battery?
OK, I think the culprit is actually the equalizer built into doubletwist... I turned off the eq and the drain slowed down significantly. With the EQ on, my battery was draining at a rate of 13% per hour. With the EQ off the battery drained at 5.5% per hour. Much better!
