(also posted this at RW, but not sure everybody goes there.) one feature that I use on every phone is to disable background data. That means I just have to turn it back on when I want to access the Android Market, etc., but it saves a ton on the battery. On my GNex, I can't find the setting to do that? I see that under "Settings > Data Usage", I can turn off "Mobile Data", but that shuts off all data (3G, etc.) to the phone. Where can I keep my 3G/4G data on the phone, but turn off the background data? Edit: Does disablilng background data really save that much on battery, or should I just not worry about it?
