Direct answer: The iPhone 13 Mini (5.4") and 13 Pro Max (6.7") share almost nothing in screens, batteries, back glass, or housings — but they DO share flex cables, charging port assemblies, speakers, motors, and several internal connectors. Rule of thumb: order screens, batteries, back glass, cameras, and housings by exact model; order flexes and small modules by series. When in doubt, check the product listing — never assume.
The iPhone 13 Series Parts Matrix
| Part | 13 (6.1") | 13 Mini (5.4") | 13 Pro (6.1") | 13 Pro Max (6.7") |
|---|---|---|---|---|
| Screen | OLED | OLED (smaller) | OLED 120Hz ProMotion | OLED 120Hz (largest) |
| Battery | ~3,227 mAh | ~2,406 mAh | ~3,095 mAh | ~4,352 mAh |
| Back glass | specific | specific | specific (matte) | specific (matte) |
| Rear camera | dual | dual | triple | triple |
| Charging port | shared flex family | shared | shared | shared |
| Flex cables | mostly shared across series | ✓ | ✓ | ✓ |
| Taptic Engine | shared family | shared | shared | shared |
Rule of thumb: screens, batteries, back glass, cameras, and housings are model-specific. Flex cables, charging ports, speakers, motors, and small flexes are usually shared across the series — but always confirm per listing.
The 13 Pro Max Special Case: ProMotion
The 13 Pro Max has the ProMotion 120Hz display — a higher-spec OLED than the standard 13. Replacement screens must support 120Hz; cheaper “compatible” panels may silently drop to 60Hz and look wrong. Always buy ProMotion-capable screens for Pro models and test the refresh rate before sealing. Full detail in our 13 series screen guide.
The 13 Mini Special Case: Supply
The Mini is the smallest and its parts are less commonly stocked — fewer suppliers carry them, which means stable demand and less price competition. Its screen is a 5.4" OLED. If you serve the Mini, keep 2–3 panels in reserve.
