As an experiment I set all my internet apps - backup assistant, gmail, people, calendar, news, weather, amazon, stocks, facebook, etc, etc, ETC, to not automatically update, sync, refresh or do anything on the internet without my say-so.
I then turned off my phone, put a full charge on it and turned it back on again to reset the timer for Settings > About phone > Battery > Battery use.
For the next 6 hours I made a few phone calls while I was not in range of any wifi; I used a few local (non-internet) apps like calculator and stopwatch and camera but I did NOT use any internet apps. At the end of that time "battery use" showed Wi-Fi at 30%, Cell standby at 28% and voice calls at 6%.
So why is WiFi so high? Is that just from some "keep alive" or beacon or polling feature? Or is there some app or process I don't know about using the WiFi connection, and how do I tell?
Thanks in advance.
