Just got your iPhone 15 Pro and wondering how to turn it off? You’re not alone. Apple’s newer iPhones, including the iPhone 15 Pro, no longer use the traditional “long press power button” method that older iPhones had. Instead, shutting down now requires a different button combination or navigating through settings.
In this guide, we’ll walk you through all the ways to switch off your iPhone 15 Pro, step by step. Whether your phone is working normally, frozen, or you simply want to restart it, we’ve got you covered.
Why Learn How to Switch Off iPhone 15 Pro?
Shutting down your iPhone can:
-
Help fix minor glitches ⚡
-
Save battery when not in use 🔋
-
Refresh memory (RAM) 💾
-
Allow safe SIM card changes 📶
-
Give your phone a break when overheating 🌡️
Knowing the correct shutdown method ensures you don’t accidentally trigger SOS mode (which happens if you press buttons incorrectly).
Method 1: Power Off with Buttons
This is the fastest and most common method.
-
Press and hold the Side button + Volume Up (or Volume Down) button together.
-
The Power Off slider will appear on screen.
-
Drag the slider from left to right.
-
Your iPhone will power down in a few seconds.
👉 Tip: Don’t hold only the Side button, or you’ll activate Siri instead.
Method 2: Shut Down from Settings
You can also power off without pressing any buttons.
-
Open Settings.

Tap General.
-
Scroll down and select Shut Down.
-
Drag the slider to turn off.

If your phone is unresponsive, you’ll need a force restart.

Quickly press and release Volume Down.
