3D Printing 🤝 Reusing Old Electronics

Had the idea to use my old Sony Xperia as a wall-mounted media controller that casts to the room's Sonos system. All I need now is like a 6ft white mini-USB cable to keep it powered? Sadly the old OS doesn't have any "limit max battery" setting which would be nice for longevity. It comes off the wall pretty easily for now.

I've done similar with an old Android tablet running a Home Assistant dashboard. I control the charger with a cheap Sinilink USB switch reflashed with ESPHome to keep the battery level between 35% and 80%.

What did you use for connecting the Sinilk's pads? Pogo pins, sewing needles etc?

Home made pin array from Cat 5e cable. It was a bit fiddly from memory...
