The browser is slated for phones and computers. If anyone wants to try it out, I built it and stuck it in a ZIP file here (link will die in 7 days):

Just run the Brave.exe after unzipping the folder. Said build is naturally provided with no guarantee of anything. All I can guarantee is that I didn't add anything to it, just downloaded the source from Github and built it.
I used it for a few minutes. It's pretty early in its development, no extensions, no user-changeable settings (at least in my build), so all you can really compare is general browsing/page-loading speed (unrelated to your bandwidth, anyway). Seems the built-in ad-blocking isn't working yet (again, unless I did something wrong in my build, I'm not a node.js guru).
