Thanks for posting in the Apple Support Communities stiven146,

If you haven't yet, try the following steps first:

1. Press and quickly release the volume up button.

2. Press and quickly release the volume down button.

3. Press and hold the side button until you see the Apple logo.

5. If your phone doesn't turn on, follow these steps to check your hardware and charge your phone. You might need to charge for up to an hour.

6. If your phone still doesn't turn on, contact Apple Support.

The following page provides these steps along with additional guidance, and what to do next if you need more help: If your iPhone won't turn on or is frozen

Cheers!
