About this site & how the report grades parts
This site is run by the dcfx team. We build the iPhone configuration lookup, a tool that reads the part identifiers an iPhone writes into its own sysdiagnose archive and turns them into one report: who made the display, battery, cameras, storage and memory, and which modem the phone uses. The guides on this site explain the same data so you can also check it by hand.
What the lookup reads
- Display:
raw-panel-serial-number. The first three characters indicate the panel maker. - Battery:
BatteryInstalled(serial),NominalChargeCapacityPercent(health),CycleCount. - Cameras:
BackCameraModuleSerialNumString,FrontCameraModuleSerialNumStringand the telephoto / ultra-wide module serials. - Memory:
dram-vendor-id(01000000 = Samsung, 02000000 = SK hynix, 03000000 = Micron). - Storage and baseband: NAND vendor/type/capacity and the modem chip ID.
The archive is unpacked in your browser; only the extracted configuration fields are sent to build the report.
How each part is graded
Grades are labels (Top, Mainstream, Standard), not lab measurements. Every part Apple ships passes Apple's qualification.
| Part | Top | Mainstream | Standard |
|---|---|---|---|
| Display (panel prefix) | G9N, G9Q (Samsung), GVC (LG) | G9P, G9L, GVE, GH3, GH5, DKH, C01, other known prefixes | GH8, GK3, J5V (BOE), C31, C61 |
| Battery | Health ≥ 95% | 85–94% | < 85% |
| Rear camera | LG Innotek (DN8, GCF) | Cowell (DNM) | Other |
| Front camera | LG Innotek (GCF) | Foxconn (FOW) | Other |
| Storage | Samsung, Kioxia (Toshiba) | SK hynix, SanDisk / Western Digital, Micron | Other |
| Memory | Samsung, or ≥ 12 GB | 8–11 GB | < 8 GB |
| Baseband | Qualcomm X55–X85 / SDX / MDM | Apple C1, C1X, C2 | Intel XMM |
The overall score combines the display, rear camera, front camera, battery and storage grades. Telephoto, memory and baseband are shown but don't change the total. The baseband grade describes the modem generation, not signal strength.
What the report can't tell you
Only Apple's Parts and Service History (Settings → General → About) can say whether a replaced part is genuine. A known maker name doesn't prove a part was never replaced, and an empty field ("--" or Unknown) doesn't prove a part is fake. See how to check if iPhone parts are original.
Editorial rules for the guides
- Settings paths and part labels are checked against Apple Support pages, which we link inline.
- Supplier claims (who supplies which model) are attributed to named industry sources and marked as reporting. Apple doesn't publish per-model supplier lists.
- Community-sourced data, such as panel-prefix lists, is labelled as such.
- Report images are samples from the tool's interface, captioned as samples, not results for a particular phone.
- Each guide shows its last updated date. We revise guides when Apple changes its documentation.
