I'm going with no. But want to note battery LIFE.
by R. Proffitt Forum moderator / April 21, 2011 3:39 AM PDT

The common laptop battery is a 300 cycle affair. The exact definition is elusive with one being that at 300 cycles the capacity is either half or 80% of new. Either way the lesson is clear. Use the battery sparingly, use AC whenever possible.

There's a lot of old bad advice still out there. Most of it is from the days of NICD and NiMH days but for today's LiON and such we can let it stay charged up all the time.

It can depend

It can depend on a lot of things. Wireless streaming will likely use more power than wired, especially if it has to crank up the gain to get a signal, and fight through all the interference from everyone else trying to use the one access point for the entire hotel. Also, if you're streaming a 1080p video as opposed to say 480p, it will certainly require more energy to process the extra video data.

There are a lot of things that can affect battery run time, so this isn't necessarily an issue.

The Samsung RF23M8090SG

One of the best French door fridges we've tested

A good-looking fridge with useful features like an auto-filling water pitcher and a temperature-adjustable "FlexZone" drawer. It was a near-flawless performer in our cooling tests.
