When not using Google Play services (e.g. GrapheneOS, LineageOS users), Signal can be a real battery drain. Molly with UnifiedPush on the other hand is extremely battery efficient.
Here’s how to set this up, using Nextcloud as the UnifiedPush provider.
I guess I don’t really have a reason to access my phone via my computer. Everything I use has a desktop interface — Signal, Facebook Messenger, WhatsApp, Telegram, my radio app, my podcasts app, Spotify, etc.
But it’s good to have alternatives if something comes up! Thanks for the tip!
