This is a super common issue following back glass replacement on most iPhone models.There is typically a small gap in the chassis where the flex cables lives. It's all too easy to accidentally nick it when removing the old back glass. The little arm of the cable that handles the power button is extremely narrow. So it doesn't take much.

Hi Samarjit,

Yeah, that's the problem with back glass replacements - you end up exposing the phone's internal components to the high heat needed to get the glass off. In addition, since the wireless charging coil is exposed, it's susceptible to a random piece of glass or a slip of the prying tool.

On the iPhone 12 Pro Max, the power button is integrated with the volume buttons, the ring/silent switch and the wireless charging coil. Chances are very good either the heat or a tool damaged that assembly, resulting in a non-functional power button. Here's the part you need.

Unfortunately I haven't been able to find any guides to replacing that part. The best I can suggest is to watch some teardown videos and use what existing iFixit guides there are to take out the components as they're encountered in the videos. Here are a couple to get you started.

Since you're blazing new trails here, it would be awesome if you could take pictures along the way and create a guide for others who end up with the same problem.

when I am replacing the power button it only clicks towards the middle. When I click toward the bottom of the button nothing clicks. Do you know what I can do to fix this issue? I have been trying for hours now


@samarjitdebnath I would take a look at the physical button itself and make sure it's undamaged and correctly mounted. There's an iPhone X guide to those buttons that will help with taking it out and reinserting it.

Start at Step 72 and be sure to check out iPhoneRepairGirl's video.
