iPhone X teardown reveals TrueDepth camera system, stacked logic board with 3GB RAM, L-shaped dual-cell 2,716mAh battery, and Qi-based inductive charging coil
Ten years ago, Apple introduced the very first iPhone, and changed the world. Today, we're taking apart Apple's 18th iteration …
Context & Ripple Effects
The iPhone X teardown lands a year after iFixit and 9to5Mac opened up the iPhone 7 Plus, where 3GB of RAM and a bigger Taptic Engine were squeezed into the space freed by dropping the headphone jack. The X extends that same space-reclamation playbook further: a stacked logic board, an L-shaped dual-cell 2,716mAh battery contoured around components, and a Qi-based inductive coil where the jack used to sit.
What is genuinely new is the TrueDepth camera system, which gives Apple a sensor cluster with no counterpart in any prior teardown in this coverage. The follow-on iPhone XS teardown confirms the pattern held — notched L-shaped batteries became the default shape for the line.
First-order effects
- Repairability drops immediately: the stacked logic board and dual-cell L-shaped battery make component-level replacement harder than on the flat-board iPhone 7 generation, raising third-party repair costs from day one.
- Apple's component suppliers now ship to a tighter mechanical budget — the battery must be custom-shaped and the board double-stacked to fit the TrueDepth array and charging coil.
Second-order effects
- Qi-based inductive charging pulls the accessory market toward wireless pads and cases built around the X's glass back, since the metal-backed iPhone 7 designs excluded it.
- Rival flagships face pressure to match both face-unlock-grade sensing and wireless charging, pushing their own BOMs toward more integrated, harder-to-service stacks.
Third-order effects
- If the XS-era confirmation holds, dense stacked boards and contoured batteries become structural defaults for premium phones, trading serviceability for internal volume — a shift that pushes independent repair further toward module swaps rather than board-level fixes.
- Teardowns themselves harden into a standard competitive-intelligence step at every flagship launch, as this coverage chain from 2016 through 2018 shows.
The trend: Flagship phone design is converging on densely stacked, contoured internals that prioritize sensing and charging features over repairability, with each teardown confirming the previous year's layout as the new baseline.
