When your iPhone 12 Pro Max is powered down, turning it back on is easy. Just press and hold the right side button until the Apple logo appears. If your iPhone is unresponsive, you can force it to restart.
Use this method if your iPhone is frozen or unresponsive and won’t power down normally.
If you want to turn off your iPhone once it’s back on, unlock the screen, and then press and hold either volume button and the right side button at the same time until you see the power off switch. Then, drag the power off switch to the right to turn it off.
