I primarily use Firefox on my desktop, but I use Brave on mobile. It seems somewhat easier on the battery than Chrome, which would make sense being as it's blocking content that can be CPU intensive. You might like it, though. I've used Brave's mobile sync and it works for bookmarks across devices quite well. It's surprisingly simple to set up, too. I don't fret much about forgetting whether I opened a tab on my phone or desktop if I remember to bookmark it. That said, I still use KDE connect to send links to my primary Firefox instance and vice-versa, but the bookmark sync is in some ways more convenient. I'd imagine they'll eventually synchronize more things, like tabs.
