We don't know a lot about how the government spies on us, but we know some things. We know the FBI has issued tens of thousands of ultra-secret National Security Letters to collect all sorts of data on people -- we believe on millions of people -- and has been abusing them to spy on cloud-computer users. We know it can collect a wide array of personal data from the Internet without a warrant. We also know that the FBI has been intercepting cell-phone data, all but voice content, for the past 20 years without a warrant, and can use the microphone on some powered-off cell phones as a room bug -- presumably only with a warrant.
