What do I do if my iPhone won't turn on at all?

Force Restart is a reliable way to fix iphone won't turn on, as it can resolve deep system freezes that prevent the device from booting normally.

Most people do this wrong. Here's the exact timing you need to follow.

First, identify your iPhone model. For iPhones with Face ID: Press and quickly release the Volume Up button. Then press and quickly release the Volume Down button.

Next, press and hold the Side button. Keep holding it for 30–40 seconds, even if nothing appears on the screen. Release it only when you see the Apple logo.

Don’t give up after 10 seconds—keep holding for 30–40 seconds.

For iPhones with a Home button: Press and hold the Home button and the Side button at the same time.

Keep holding for 30–40 seconds, then release when you see the Apple logo.

This method can help you fix iphone won't turn on caused by software crashes or deep freezes, but it cannot resolve hardware-related power issues, so it is only suitable for users whose iPhones are unresponsive due to software problems.

If you don't want to move straight to recovery mode, you can try this method. This is a simple, safe measure, but you should follow the timing carefully to ensure it works.
