I've owned three Rokus for several years without any problem. One has 4k capabilities, the other two don't. In the last two months, the non-4k units in separate occasions have gone berserk and consumed 600GB of data in one day. Given that they gave no problem for years, I assume it must be something introduced by the latest software updates. I'm not using them anymore
In the settings, there is a bandwidth saver. Make sure that is turned on. Also, whenever you are done using an app, you should ideally exit out of it cleanly. In most, just keep hitting back until it either exits or asks to verify to exit. For some, like Netflix, you have to choose a menu entry. For Netflix, it's the left-side menu, at the very bottom. Hitting HOME to exit may cause some apps to get stuck and keep streaming.
Thanks, but there has to be something else. A non-4k Roku cannot normally go through 600GB of data in a day even if it is continuously streaming. Also, as I mentioned, this was not an issue for many years.
How are you measuring the data? I ask because I used to have a router with a traffic meter that was fine (and presumably accurate) until I would launch YouTube on a Roku. (Other apps on Roku did not cause this effect.)
Once I ran YouTube on a Roku, all data use metrics on the router would be messed up (Terabytes too high) until the next month when the router reset its data meter. Something about the Roku YouTube app (of that era) would cause the router traffic meter (of that era) to add an uninitialized variable, or something similar, that caused it to show ridiculous data use. At the time, I was using an ISP with a data cap but fortunately, their meter didn't have the same bug.
