Does Ubuntu Touch consume less power than Android?

So someone asks if Ubuntu Touch consumes less power, and another person replies basically "Maybe, nobody knows yet."

How is this Hacker News worthy?

This doesn't say how much less power. Is it significant? iOS also doesn't have a VM but that doesn't make it easier on the battery vs Android, so why would that be the reason for Ubuntu? Perhaps Ubuntu just doesn't have a lot of services running in the background currently?

Not sure why you were downvoted, this really is a useless submission.

While true, that's like saying i++ is more efficient than i = i + 1 in an application that makes several SQL queries per run.

You can micro optimize areas of code for better CPU (and thus battery) efficiency, but the largest use of power in a phone is the cellular radio, WiFi, bluetooth, screen, digitizer, and other bits of hardware. The CPU makes a difference, but most likely not in a noticeable way
