Apple quote 18h of Apple TV playback or 12h of web browsing so I will call a large amount of bullshit on that.
Even considering the marketing, best case scenario you would be between 27 and 41% battery consumption for 5h of runtime.
The actual number will be lower than that because you probably don't use the MBP at the low brightness they use for marketing benchmarks and game streaming constantly requires power for the wifi chip (video can buffer, hence the lower consumption).
There is no way to say this nicely, but can you stop lying ?
