Maybe we're doing something different, but I cannot get my Nexus One to stay alive for longer than 5 hours with an active net connection. It if it's a low-traffic connection (calm IRC channels, occasional email polling) it will last a day (same with my G1) but streaming radio, etc will leave it dead in a long afternoon.
Ah.. Streaming radio. By active net connection I thought you meant email polling, IM, etc.
Playing streaming video will kill the battery pretty decently, but IMHO that seems fair. Your keeping the radio pretty busy, the audio hardware, the cpu, etc.
I'd actually like to hear from an iPhone user whether they can run Pandora or Last.fm for 5 hours straight without killing their battery either.
I'm an iPhone user as well, and it also kills the iPhone. the point was that on iPhone, 3rd party apps are not given the opportunity to do this without the user being aware (because it's in the foreground.) i've had a runaway android app kill my phone after it screwed up and started devouring resources in the background while it was in my pocket.
The user would have to be aware of streaming audio. Also, as stated elsewhere in this thread, apps don't normally run in the background on Android either. I'm curious what app you believe killed your battery life in the background? That sounds... unusual.
Apps normally run in the background all the time in Android. I know which app it was (meebo) because I can view the stats afterwards. Also, to help alleviate some of your confusion, we are talking about background processes, not just streaming audio.
Apps only run in the background if they specifically register a background service. Usually this is when you click a button in the apps preferences like "update in background", etc.
