Power on with charger cable

[tallnessuk]

Is there a way to power up the s9 when the charger is plugged in, then power off again when unplugged? Its for a car project

Nope. At least not turning on. Find one with a bad enough battery and it'll probably power off when the power is off but finding one to turn on just because it's powered, that's going to a trick. There were some older phones that did this, well at least one old phone, because I remember seeing posts asking how to stop this behavior. That was in the early 20 teens if memory serves.

Best wishes.

Windows phones did that... powered on when you plugged them in to charge. I hated that lol.

A MacroDroid macro can be triggered by the power being disconnected and used to turn the phone off (needs the phone to be rooted though).

Tasker could also turn it off but again requires root.

It's technically possible but would likely require a custom ROM to enable it. My old Note tablet powers on automatically when plugged in ever since I rooted it and installed a ROM, personally it annoys me.
