How to Seal Your iPhone With Books

Introduction

This guide shows how to activate your iPhone's pressure sensitive adhesive (PSA) with heavy books, once you're done with repairs and are ready to seal it up.

The procedure works with all iPhones that don't have a physical Home button. The guide's written with an iPhone 16 Pro Max.

Step 2

Place your iPhone screen-side down on a clean, flat work surface.
Lay a strip of tape around the perimeter of the back glass to protect the finish.
Stack coins around the perimeter of the back glass until you create a wall that's as tall as the rear camera protrusions.
Alternatively, you can use vise clamps around the perimeter of your device to set the new adhesive.

Step 3

Place 3-4 heavy books squarely on top of your iPhone.
The coins may leave a slight impression on the bottom book cover, so don't use anything valuable.
Leave the books in place for about 30 minutes.
The pressure will help activate the adhesive.
