The default setting will enable you to stream about 3 hours of TV shows and movies per gigabyte of data. In terms of bitrates, that currently amounts to about 600 Kilobits per second. Our testing found that, on cellular networks, this setting balances good video quality with lower data usage to help avoid exceeding data caps and incurring overage fees. If you have a mobile data plan with a higher data cap, you can adjust this setting to stream at higher bitrates. Our goal is to give you more control and greater choice in managing your data usage whether youre on an unlimited mobile plan or one thats more restrictive.
