Arc vs Zen Browser Energy Comparison on MacOS

I am currently using Arc which works great for me, only issue is it drains my battery too fast for my liking (10-15% /hour). I'm thinking of switching over to Zen, and while I don't like the UI as much as Arc, I'm willing to make it work if it has good power consumption compared to Arc. Has anyone used both these browsers on Mac and noticed whether Zen is less resource intensive and is the way to go?
