I'm new with this Android thing, a HTC Desire btw., and i'm playing around with the settings to get to know my phone. But there is one little issue i can't figure out. I reacently downloaded a Weather App from the national weather forecast center (DMI), and placed 2 widgets from it on my homescreen. I have a 1G data limit pr. month, witch should be more than enough for my use, but i keep Background data turned off just to be on the safe side. When i installed Watchdog, i realiced that my phone can easily use 25Mb overnight if my wifi is off to save power. Background data is off. I kill almost all apps (including the DMI weather app, and apps i never use like facebook and a preinstalled news app) using Advanced Task Killer (free) before i go to bed. So here is my 2 questions: Why do some apps like facebook frequently show up on my list of running tasks eventhough i do not use them, and how do i turn that feature off (to save power)? Why do some widgets and apps use data eventhough Background Data is off, and how do i make them stop without disabeling the mobile internet connection? It seemed removing the DMI widgets reduced the overnight datausage, but acording to my Watchdog, i still use 2-5Mb overnight dispite the fact that Background Data is off, and the DMI app still shows up as a running Task in the morning.
