I recently posted a blog that helps device owners know what to turn off so it saves on battery. http://community.sprint.com/baw/community/buzzaboutwireless/phones-and-devices/android_phones/evo_4g/blog/2010/06/15/battery-tips-for-new-evo-users.
Hope this helps, let us know.
Correct answer to your question of which services to stop is NONE. It is important that you let Android run whatever services that it needs to run, otherwise you could miss phone calls, texts, etc. Don't use task killers either.
If you feel that you really, really, really need to turn stuff off, only stop the services that you know are connect to a certain application.....ie, the Sprint TV widget (which ALWAYS kicks on, this has been a problem with Sprint Android devices from October 9th, 2009 that they haven't fixed -- its lazy coding in their applications).
Izzy's article is a good one, there are a lot of new things in Android and it takes a couple days to get used to them.
I purchased my HTC EVO 6 days ago and absolutely love the phone and all the things I can do with it. However, the battery life is disturbing, I fully charge the phone before I go to bed, when I wake up in the morning I read my emails and the news and "bingo" the battery is down by almost 35% considering that is was dormant all night and reading a few emails and the news in the morning to me seems excessive. I read your suggestion to leave the system handle the battery use itself, do you still fell that way? Suggestions?
Disable home screen widgets. Tap on a widget and goto "Settings". Disable the widgets you are not using or consider disabling all of the widgets on your home screen. Widgets use a lot of battery life.
Install a task manager. Many HTC Evo users recommend installing a task manager application on the HTC Evo to help extend battery life. Launch the "Android Market" and search for a task manager. Download a task manager application and look at which services are running. Kill certain services such as "Camera" to save battery life.

>> Check android market place and reviews:
People keep recommending it because instead of doing their own research based on current information, they are just repeating what they have been told or have read. In 100% of these cases the recommendation is based on old information, usually related to old versions of Android. Android 1.x had memery consumption issues and the task management applications did help. The newer 2.x Android software however has a dedicated system for managing memory usage and closing applications when memory is needed for other applications or activities.
It is much like the change Microsoft made when going from XP to Vista. Entirely new system for memory management that people don't understand and still work off of old information about how the old system managed stuff. This kind of thinking then causes a ton of issues with the new software because assumptions re made that, while valid before, no longer apply and just cause issues.
Do task management applications have their place? Of course. Does the average Android user running on a current device need them? No. Unless you are working with applications that have known memory leak issues, or you are developer working on a known bug-ridden app then you don't need one. Some management applications like what Samsung has integrated into the Epic 4G provide additional information that is helpful for the everyday user that most other applications don't. For example you can managed installed applications from there, it also shows when applications are actively using the CPU (red highlight), and therefore won't let the device go to sleep when you turn the screen of, thereby causing excessive battery drain.
Sprint is proud to have been named to The Civic 50, an annual survey of America?s most community-minded companies.
