Yes, it does. I think it polls for bt devices regularly -- not sure what the interval is, but it seems to be less than a minute. Every bit helps.
Some other tips:
- Turn off auto-brightness, and adjust the brightness down to below 50%
- Turn off location services for apps that really don't need them, such as games, web browsers, news apps like AP Mobile...etc.
- Turn off notifications for apps you need to be notified on.
- Close apps when you are finished with them (double click home, hold an App until it wiggles, and hit all the red minus signs to close the apps)
- Turn off integration of contracts with apps such as Mapquest..etc. (In Privacy settings)
- Fetch new mail hourly instead of instant or push
- Log out of applications (don't just shut down the app) such as Facebook when done. Simply shutting down, but not logging off means location services and notifications will still be active, and using battery life.
- If you really want to save battery life, switch the phone to Airplane mode when you know you won't be expecting calls/emails/texts..etc. (Ex: if you are taking a long motorcycle ride and won't be accessing the phone)
I get about 2 days of life out of a full charge (1.5 year old iphone4), but I use my iphone minimally
