I had facebook only as additional running services. All others services will only activate base on google services or social networking services.
As an example, previously I had "Smooth Calendar" app running at the background but actually it has features where you dont really need to update it in real-time. It will look for update after an hour. This could save your battery and phone performance.
Another example is, I set my TweetDeck to update manually. Means, when only I want to read, I update the content. Most of the time to save my network data usage, I download it when Im on WiFi.
Facebook update hourly.
You may check you email update frequency and the rest of your apps.
Save battery..better performance..
