This is another reason I so wish cyanogenmod / google / apple will hurry up and 1) Create a guest account for my phone 2) make it possible to disable all background data sharing /synching save for a whitelist. This would both conserve battery and it would be so much easier to decide what applications gets acces to what. E.g. my antivirus wants finegrained location data, but works fine with coarse... (I should really uninstall that antivirus program).
