Well, it's not quite that chaotic on the Android...it boils down to how well written each app is. A well built app will give you settings to control how much data syncing is going on over the network, when, if it should only be over wifi, 3g or both, etc.beje said:Quoting myself as I got no response. Currently, I'm reaching about 200MB monthly with my symbian handset, but it's a completely different approach. I know Nokia is not so popular in the states so I'll give you some info: with symbian, every app is in its own "sandbox" and you have complete control on which apps are currently open, how do they access to the net and when can they do it. With Android you have... CHAOS. The only concept of having to download a third party app to be able to kill any task because they stay in the background eating megabytes by default (sometimes without an option to "exit") just baffles me... so I wanted to know if, in the end, data usage ends up being much higher or not.
Anyway, according to my monthly Tmob bill, my data usage is averaging out to about 250 MB a month, with a high of 380 MB and a low of 150 MB. That's daily checking of mail, web browsing (esp. RSS feeds), regular use of Maps app for various info, syncing various apps like Calendar, Tasks, Facebook, Twitter, etc. Some IM, and also most of my SMS goes through Google Voice, so that should be on data as well, but I'm not a heavy texter/IMer. I do very little media streaming, just the occasional Pandora session and YouTube video here and there.
Hope that helps
