it would probably be a great way for people to get their feet wet if they dont have a server, but maybe not a great long term solution due to possible battery issues (unless its a phone that supports bypass charging)

most people have an old phone lying around that could be set up fairly quickly with something like syncthing for some basic file synciing, or run some services using termux along with tailscale or netbird so they can be accessed when away from home. all that would still be a bit of work but it would be a lot less daunting than all the research you have to do when youre getting into self-hosting. server/nas hardware, disks, how you are going to set them up, what OS to install etc etc

“bypass charging” is becoming a bit more popular now. you see it on some android gaming tablets where it bypasses the battery once a cable is plugged in, which makes sense considering how quickly the battery would run down on those. i think i saw the recent google pixel devices having this feature as well so many it will just be a thing on all phones eventually
