[Q] Does background apps use Data?

---

Hello All,

I got my captivate recently and love it so far. I have read several articles on whether the background apps/tasks consume battery or not. I guess the Android community is split between whether background tasks should be killed or left alone for the OS to handle.

But, I have noticed that my data usage has gone up since I got the captivate (I had HTC Tilt 2 before). My question is does background apps consume data? I am not talking about the email sync and other necessary apps that are running in the background but specifically asking about apps that we have installed from market that are supported by Ads. Do they consume data in the background? Should I kill them? Can anyone recommend a good task killer? Is there a security risk if these background apps keeping sending back and forth data?

Any insights in much appreciated.

Any help please?

Apps that are not running should not use data; but there are other things that do.

Widgets use data - do you have a weather widget? News, social networks, contacts or calendar?

Gmail, Exchange, AT&T - all have address book and calendar sync that is going on and constantly checking for changes. 3rd party apps with ads should not be a concern - they should not be using data when not running.

As for security risk - it depends as i don't know what apps you have installed. When you install an app it indicates what it has access too. If a checkers app has access to contacts, phone, and gps then i would be concerned.

Using the free version of Juice Defender I was able to configure which apps could use data when in background and which ones would only be able to use data if they were in the foreground.
