iPhone 13 Mini & 13 Pro Max: Parts Compatibility Cheat Sheet
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.

Grade A vs OEM iPhone Screens: Quality Tiers Explained
In the parts trade, “OEM” loosely means original-manufacturer quality, but true Apple-genuine panels are hard to source and expensive. What you actually buy is graded aftermarket: Grade A (best), Grade B, Grade C. For repair shops, Grade A screens ($20–60 wholesale depending on model) are the sweet spot — near-OEM quality at 15–30% of the price. Buy Grade A, test every unit, and ignore label hype. Read more...
Back Glass vs Back Housing: What Repair Shops Need to Know
Back glass is just the glass panel mounted over your existing frame — fast and cheap for cracks ($10–35 wholesale, 40–70 min). Back housing is the complete frame assembly (frame + glass + brackets + buttons) and you transplant all the internals into it — the fix when the frame is bent or a color change is requested ($25–80 wholesale, 60–120 min). Pick back glass for glass damage; pick back housing for structural damage.

iPhone Home Button & Adhesive Strips: Compatibility Guide
Only iPhone 7 and 8 series still have Home buttons — and each button is paired to its phone at the factory. Swapping one kills Touch ID unless you transfer the original button. Adhesive strips, by contrast, are cheap ($1–3), universal to stock, and mandatory for every screen and back glass job. Rule: always transfer the original Home button; always use fresh adhesive.

iPhone Vibrator Motor & Loudspeaker: Replacement Guide
A dead vibrator is almost always the Taptic Engine ($3–8 wholesale, 20–30 min swap). A muffled or silent loudspeaker is the bottom speaker assembly ($4–10 wholesale, 20–35 min). Both are cheap, simple repairs priced at $50–90 — and they’re the perfect “while the screen is open” add-ons that add $40+ margin to almost every repair. Read more...
iPhone Camera Replacement Parts: Front, Rear & Flash Guide
iPhone camera failures fall into three parts: the rear camera module ($8–35 wholesale, 30–45 min install), the front camera + proximity assembly ($6–15, 15–25 min), and the flash flex cable ($3–8, 20–35 min). Blurry photos, a black viewfinder, and a dead flash are the three symptoms — and all three parts are cheap, fast repairs that shops price at $50–160. Read more...
