I purchased a hub to connect the lan cable and usb pendrives to my mba and I noticed that when I put the mba into sleep mode it still provides power to the hub, draining battery. Is there a way to avoid this apart from disconnecting the hub everytime or completely powering off the mba? Thanks for your patience.
Got a tip for us?

Why in stop mode the mba is still powering the hub?

Closing the lid does not automatically put the MacBook into hibernation mode where is writes the ram contents to the SSD and powers itself off.
Sorry, I don't understand, in other terms? I did some tests and noticed that if I switch the mac completely off (shutoff) there's no power to the usb peripherals but if I chose "sleep" mode, the power is still provided. And in both cases, the lid position is uninfluential. I like to put the mac into sleep mode but this will force me to phisically disconnect the usb hub every time, not a perfect solution. Any idea?
Some people use the word sleep and hibernation interchangeably.
Here's my interpretation of sleep: Macbook is put into a low power state but is still running off battery.
This is my interpretation of hibernation: MacBook's ram contents are written to the SSD and powered off completely.

Hibernation mode powers everything off for me, including attached peripherals, while sleep will not.
I apologize if I am not providing you with any information that is helpful.
You may be correct.
All I can say is that I don't have this problem with my 2015 Air or 2013 Pro.
They (Intel machines at least) do, but it's not user selectable. The Mac will automatically enter hibernation if while sleeping the battery is close becoming depleted. However that is irrelevant to your question.
I would expect your sleeping Mac to stop powering the hub, if not immediately upon sleep then shortly thereafter.
Useful for wake on lan, charging your phone etc. Could imagine it also depends if your Mac are connected to charger or not.
Intel Macs definitely have hibernation. While not directly user accessible, there are several 3rd party apps that will put the Mac directly in to hibernation mode (write the contents of RAM to the SSD and then power the machine off).
I have no idea actually if the M1-based Macs have a hibernation mode. Haven't investigated yet.
