If Sync ever did that, I would be over the moon. That app made browsing a genuine joy with how good the UI is and how customizable it is. I really hope the devs for the existing third party apps repurpose them or make a version for the fediverse.

One thing that I can offer advice on to help battery life and overall enjoyment: use per game profiles.

I have my Steam Deck's TDP set to 6 for emulated games most of the time and 8 for more intense games. I run ESO at pretty high settings and get 2-3 hours.

The other being set your framerate to 40 capped unless playing an emulator.
