The first foldable iPhone deserves a different kind of durability coverage. The hinge, inner display and outer shell all need separate attention.
Apple says iPhone Duo uses a Grade 5 titanium frame and hinge cover, a scratch-resistant inner display coating and Ceramic Shield on the front and back. That is a design claim, not a substitute for long-term independent testing. Early reports should be read for test setup, hinge cycles, grit exposure and whether the inner screen was touched with a sharp object.
How to read this result
Tests are snapshots, not guarantees. When comparing phones, keep the method, software version, screen brightness, network and starting conditions in view. We update this page when better evidence appears.
What a fair test should show
Results only mean something when the conditions are visible. Look for the software version, brightness, network, temperature, battery health, starting charge and the exact endpoint. If a report leaves those details out, treat it as useful colour rather than a controlled comparison.
What this means for owners
iPhone Duo has a published baseline of 7.6-inch inner OLED; 5.4-inch outer OLED and A20 Pro. Those specifications explain the platform, but they do not remove the differences created by signal strength, app mix, storage choice or personal habits. The practical conclusion should remain proportional to the evidence.
Read across the range
Use this report alongside the iPhone Duo model page and the full comparison table. Reading one result in isolation is how small test differences become exaggerated buying advice.
