The other possibility is that your device downloaded and installed a rather large firmware update.
Have removed google sync and every other kind of syncs there are, I even disabled background data usage, and the os still used over 100mb since yesterday afternoon.
Been playing drag racing app online like crazy for the past 2 days, but my usage says that app only used 4mb in past 2 days. So im clueless as to how im going through 1 gb of data every 3 days
