they already mentioned why it was awake: downloading updates.
...which it only does when connected to power so I'm honestly failing to understand what the problem may be. Anyway: Settings -> Software updates -> Advanced -> Download new updates when available -> uncheck.
For everything else: Battery -> Power adaptor -> Wake for network access -> uncheck (may also take care of the above, dunno)
