Roku devices don't have a standby mode or power button
Roku devices do not come with a power button or a standby mode. If the Roku device is powered by the TV's USB port, it will shut down when the TV is turned off. However, if the TV is put on standby, the Roku device will remain on. This is because the device is designed to run constantly to download updates.
If you are concerned about the Roku device using electricity while the TV is off, there are a few workarounds. One option is to use a smart surge protector, plugging the TV into the "parent" slot and the Roku device into a "child" slot. This will cut the power to the Roku when the TV is turned off. Another option is to disable the "fast start" option, which will allow the device to power down a few minutes after the TV is turned off. Additionally, you can put the Roku device into a low-power "sleep" mode by holding down the power button on the Roku remote. This will cause the Roku to stop sending a signal to the TV, allowing the display to enter power-saving mode.
If you want to completely turn off the Roku device, the only way to do so is to unplug it from the TV and the power source. This is because the device does not have an on/off switch.

Roku devices powered by a TV's USB port will turn off with the TV
Roku devices do not have a power button or standby mode. If your Roku device is powered by your TV's USB port, it will shut down when you turn off your TV. However, if your TV is in standby mode, the Roku device will remain on.
Some users have reported that their Roku devices continue to stream and burn power even after the TV has been turned off. This can be avoided by pressing the home button on the Roku remote before turning off the TV. This will prevent unnecessary data usage.
If you are concerned about power usage, it is recommended to disable the fast start option, which will allow the Roku device to power down completely a few minutes after the TV is turned off. Additionally, it is worth noting that some Roku devices, such as the Roku Ultra, tend to stay warm even when the TV is off, which may indicate power usage.
While it is possible to power a Roku device through a TV's USB port, it is important to ensure that the port can supply sufficient power. Most TV USB ports supply 0.5 amps or less, which may not be enough to power a Roku device reliably. Insufficient power can cause the Roku device to shut down unexpectedly or exhibit strange behaviour. Therefore, it is recommended to use the provided AC adapter to power the Roku device whenever possible.

Roku TVs have a Fast Start option that prevents them from shutting down completely
Roku devices do not have a power button or standby mode. Roku TVs have a Fast Start option that prevents them from shutting down completely. This option is not available on other Roku devices. When the Fast Start option is enabled, the Roku TV goes into a low-power mode, allowing for quick boot times, voice command access, and the ability to listen to music, radio, and podcasts when the TV is off.
If you want to disable the Fast Start option, you can do so through the Settings menu. By disabling this option, your Roku TV will power down a few minutes after you turn it off, and it will cool down. Disabling Fast Start may also help reduce power consumption, as the device will not be converting electrical energy to heat energy while in standby mode.
It is worth noting that Roku devices that are powered by the TV's USB port will turn off when the TV is turned off. However, if the TV is in standby mode, the Roku device will remain on. Additionally, some Roku devices, like the Roku 4, have the option to automatically power down after 30 minutes of inactivity.
Overall, while the Fast Start option provides convenience and quick access, it may result in higher power consumption, especially if the TV is left idle for extended periods.
