iPad Pro iPad Pro as a second monitor - best practices?

[alexjholland]

Hey, I often use my iPad Pro 11" as a second monitor during extended work sessions.

What's the best practice here?

• Cable vs WiFi?
• Power cable vs battery?

I seem to have three options...

1. Plug straight into my Macbook Pro M1 via USB-C to Lightning
2. Plug into a charger via USB-C and use WiFi
3. Leave it unplugged using its own battery and WiFi.

Performance seems identical over USB-C and WiFi.

My main concern is whether leaving it plugged in constantly will affect the battery.

But then... That's exactly how I use my Macbook Pro M1, too?

Advice appreciated!

I do a mix I keep it unplugged to about 40-50% battery and then plug it in.
