I am hooking up mine to a projector and using it to drive my home theater. Sound is handled by a bluetooth speaker. Is it perfect? Far from it. Is it a better experience for watching movies on TV? Absolutely.

I do the same thing. The camera on my old phone is much better than the one built into my laptop. And even though the phone’s battery is pretty much dead, that doesn’t matter since I have it hooked up and powered via usb all the time.

Take the battery out of it. Put on lineage OS. Use it as a microserver, mine some crypto like monero. Because it’s CPU-based. You could use it as a remote for other devices. You could use it as a webcam for your house. It can do everything it used to do.

Old lithium batteries become a fire hazard, so I would recommend removing it if you can. Or at least replacing it with the new battery. Good practice at least even if you break it

Leaving an airplane mode, don’t use the cellular modem, you’re not getting any hardware driver updates. So it’s security risk. Don’t do anything too sensitive with it. But just for you around home network it’s fine

Can you run phones without batteries off of AC?

Depends on the design of the phone. Some will work just fine off of USB power. Some will try to detect a battery and then fail the boot. For the ones that are more troublesome you’ll have to Google the instructions on to make a dummy battery load. The important thing is to get the lithium ion battery out of the circuit.

Thanks for you answer !

Why LineageOS ?

large hardware support portfolio, i think its the single most widely compatible ROM. As long as one crazy maintainer hangs on to your device, you will get lineage updates.

Just because you forgo hardware driver security updates, doesn’t mean you should stop getting android security updates.

I use mine as a camera in the garage when I’m working on my car so I don’t get my current phone all greasy.

Depends on the age of the phone and if it is boot loader locked by a carrier.

Music player, bedside alarm clock/weather info, time lapse camera

I use an old Nexus 5 I have as a offline GPS device for cycling.

I use an IP webcam app and run my old S10+ as a CCTV camera inside my garage, viewable in Home Assistant.

Battery powered? Screen on/off?

The app lets the screen turn off. I have it plugged in to a smart power switch, and have the HA Android app installed.

This way, I can monitor the phone’s battery level with HA and use automation to keep the battery charged between 40% and 80%.

Nice, I will check that app. In the past I used to separate apps for that and screen off didn’t work well, it would wake even if nothing happened.

Honestly, the screen being on doesn’t really worry me too much now, and I suspect an Android change in the past few releases has made it less reliable when the app tries to do it, because I’ll occasionally walk by and see that it’s on.

I’ve set the brightness all the way down and it sits up at ceiling height, on top of a wall-mounted network cabinet. I remote control it from my computer, using scrcpy (requires adb over TCP/IP).

Turn it into a pihole.
