I’ve seen cases where phones are used for testing, monitoring, background tasks, or other always-online purposes after a one-time setup. No user interaction, just keeping the device connected and running.
Curious what real-world use cases others have actually found useful. Are there setups that worked well long-term, or things to avoid?
Not trying to promote anything here — genuinely interested in how people approach this.
Just yesterday I learned the Echo Show 5 can be pwned so I dug mine out, put LineageOS on it, and now it's a satellite for my HA server. Her name is Janet now.
I used to keep one as a sort of backup internet connection, since there are "unlimited 4 hours of internet" prepaid plans, like $1, here that work pretty well when used as an access point if your home internet's down for whatever reason.
Nowadays I just sell them
Another phone is an audiobook listening device for my kids (they choose and I play).
Of course I also have a dedicated dev phone.
I can always find a purpose for an old phone. But nothing on the Internet, unless it still gets updates.
> Out of curiosity, have you found any downsides with that setup long-term? Battery health or missed notifications, for example?
Yeah, it is inconvenient to bring two phones. That's definitely a downside. Battery health is fine. I never missed any notifications so far.
I sell them or give to family.

Adding this makes me think you do want to promote something.
