Why is the com.android.browser process draining my battery? I have a Samsung Galaxy Note with stock 4.0.4 ROM. The battery drains very fast and the phone is often warm. Reboot doesn't help. Settings says that com.android.browser (Internet) uses most of the battery. I never use default browser, I only use Chrome.

I suspect that some background process it creating a heavy load and using the internet connection. I think browser is used by other applications, but I'm not able to figure out which application is related. I suspect maybe ad supported applications are the root of the problem.

Is there any solution or app to figure out the origin of the problem?
The root of the problem is Internet sync related. The system is not able to sync internet settings.
