> chess grandmaster can easily be beat by a smartphone app (komodo), is smartphone using more energy than a human brain?

I would think a smart phone consumes less power than the brain (more so if you can turn off the display appropriately). I could be wrong though. BTW does all of the komodo logic reside on the client side or some of it executes on the off-client backend ?

The logic is on the phone.
