I have installed lots of apps on my phone. For the last couple of weeks i am facing one issue. Even when i am not using internet infact even when i am not using my phone at all, a window pops up and says you have just downloaded ??mb of data!!! and because of this my battery is draining very fast. I have to charge it twice a day. I don't even know which app is accessing net,

I suspected the pulse feed reader and google+ for this. Uninstalled pulse reader but still there is problem. If i could got to know which app is that then i will just uninstall that.

Phone: HTC Desire S OS: Android 2.3.3

Make sure auto sync and background data options are turned off. –  Sparx Jul 16 '11 at 11:39

Why don't you disable wifi/3g when you don't need it? –  balki Jul 19 '11 at 6:48

PhoneUsage keeps track of how much data you use each day, and gives a nice display of which apps used how much data.

Here is an example of what mine looked like this month: enter image description here

NOTE: it only starts tracking after installation.

Check out SPB Wireless Monitor. It can give you reports by date range of which apps have used data, how much data they've used, and breaks it down so you can see wifi data vs. data-plan data.

There's a new app, My Data Manager, which costs a fraction.

You can check that out as well. It does basically the same thing, though will also show you roaming data. Also, this one allows you to enter a monthly start date so you can align its data tracking with your billing cycle.

I'm surprised that no one has mentioned Onavo! It works great! And a quite intuitive interface too!
