Putting aside the question of what is streamed, that 260MB translates to spending about $ 2 per month based on the average price of $ 8 per GB of data in the US, if the device is disconnected from Wi-Fi. -Fi all the time. Assuming half of that data is outbound, Google would receive about 4.4MB per day or 130MB per month for each device. An iPhone with Apple’s Safari browser open in the background only transmits a tenth of that amount to Apple, according to the lawsuit. Much of the data transmitted is logs about network availability, open applications, and other operating system metrics. Google could have delayed the transmission of these files until the Wi-Fi connection was available, but it chooses to spend the data of the users’ mobile to be able to collect data at all hours. The complaint claims that Google conducts these data transfers to improve its advertising business, sending “tokens” that identify users for targeted advertising and preloading ads that generate revenue even if they are never shown. “Users often never see these preloaded ads, even though their mobile data has already been used up to download Google ads,” according to the complaint.
