Introduction

Remove or replace the pentalobe screws in an iPhone 7 Plus.

Image 1/1: Power off your iPhone before beginning disassembly.
  • Before you begin, discharge your iPhone battery below 25%. A charged lithium-ion battery can catch fire and/or explode if accidentally punctured.

  • Power off your iPhone before beginning disassembly.

  • Opening the iPhone's display will compromise its waterproof seals. Take extra care not to expose your iPhone to liquid damage after completing your repair.

  • Remove the two 3.4 mm pentalobe screws at the bottom edge of the iPhone.

The recommendation of discharging the battery is completely unnecessary. Even a 25% charged battery can explode. Completely ridiculous suggestion.

The risk of thermal runaway on these batteries decreases with the battery's SOC (state of charge). Below 50% charge the risk is fairly low, and at 25% charge the risk of a thermal event is near zero. If I recall correctly, the same suggestion appears in Apple's official (non-public) service manuals for the iPhone.

Can anyone confirm 7/7P's pentalobe screws have a ring of seal near the screw head?

Hey Cooper,

There is no seal on the screw. The head of the screw simply pushes against the lip of the screw well, without using any sort of pneumatic seal, o-ring etc.

As Talon says, it is part of the casing.

I not recall seeing one. If there is one I would expect it to be part of the casing.
