I’d also curious on how’s mobile performance between two engines.
In terms of build size, defold is way better (this and this), way ahead competitors.
But how about efficiency? I mean the battery consumption and ability to run on low end devices?
My impression, defold is also better on this and godot will eat more cpu and battery.
I’m researching and really hard to find godot data on this.
Does anyone experienced with both engines can please confirm this? 
Thanks
