They aren't all perfect, but TBH, I would get by. I only miss Threema to switch fully at this point (which I've migrated many of my contacts too, so that's on me), but as work on a Matrix-bridge is ongoing there's a lot of hope. (I could also just use Waydroid + the Android app to fill this gap, but… that kills the battery (at least for the PinePhone).

FWIW battery hungriness of Waydroid should be perfectly fixable. I had a quick look and it doesn't really seem to care about not doing useless work when there's nothing to do and happily wakes up multiple times per second all the time the container is running. A lot of low hanging fruits there.
