This is my first shortcut and it is perfect for me maybe for u to ?
It sets everything off (Bluetooth, WiFi, cellular)
It sets batterysavemode on
It turns dark mode on if u want
And it sets the brightness to 1%
If u want you can activate ultra low display (this is ULTA LOW)
Tipp: if you use this disable bevore True Tone to keep the screen brightness by 1% ( iPhone 8 and newer )
