Why Does a Lightning Cable Only Charge When Flipped?
Short answer
D Inspect and clean or repair the device's Lightning charging port, since the cable works with other devices and the port is orientation-sensitive.
Question
Key Takeaways
The exam tests whether you isolate a mobile charging fault to the cable or the device; the trap is blaming the cable even though it works with other devices.
A Lightning cable recognized only after being flipped usually points to a physical problem in the device's charging port, not a failed cable, because Lightning connectors are reversible. This page confirms D: the port is dirty or damaged, and explains why the cable working elsewhere matters.
Common mistake: Choosing C is common because a flaky cable seems plausible, but the cable works with other devices and Lightning should connect in either orientation—so an orientation-specific failure points to the port.
Expert Analysis
Why the Answer Is Correct
D is the best answer because Lightning is a reversible connector: it should charge or be recognized in either orientation. If flipping the cable makes it work, and the same cable works with other devices, the likely fault is inside this device's charging port—debris, corrosion, or a bent contact on one side. Cleaning or inspecting the port is the appropriate next step. The device-specific nature of the symptom is the strongest clue that the port, not the cable, is at fault.
Why the Other Options Are Wrong
A restart might clear a software glitch, but it would not explain why physical orientation changes recognition. B battery swelling can cause charging problems, but it would not typically be resolved by flipping the cable and would affect charging more generally. C is the main distraction: a failing cable could be orientation-sensitive, but this cable works with other devices of the same type. That cross-device test shifts the diagnosis to D.
Community Comment Notes
colemajo29 explains that reversible Lightning connectors have contacts on both sides, so one-side-only charging suggests a bent, corroded, or obstructed pin in the port. Hackerpea makes the key point: "If the cable were faulty, the issue would appear on all devices, not just one." acf9805 argues for C because flipping suggests partial cable failure, but that reasoning does not account for the cable working elsewhere. prasad90 asks which answer is correct, and the practical consensus in the comments is D—inspect and clean the device's port.
Exam Strategy
Use the cross-device test: if the same Lightning cable works with other devices, stop treating the cable as the primary suspect. Then focus on the reversible connector's contacts in the affected device's port and check for debris or damage.

colemajo29 👍 2 Answered DWhy "The Charging Port" is the Answer Lightning connectors and ports are designed to be reversible, meaning there are pins on both sides of the cable and corresponding contacts inside the device's port. The Symptom: When a device only charges in one orientation, it typically means that one of the internal pins in the charging port is either bent, corroded, or obstructed by debris. The Logic: By flipping the cable, you are aligning the working pins on the cable with the remaining functional contacts in the port. Isolation: Since the user tested this with other devices and they worked fine, we have isolated the fault to this specific device's port rather than a faulty cable.

FoxCaster 👍 1 Answered D"The cable is not recognized when it is plugged into the device." "This issue does not occur with other devices of the same type." The question prompts us with two nouns, separately: • Device • Cable The sentences, I typed above, signifies that the device, that is using the cable, is defective. (It does not recognize the cable when plugged in). Furthermore, the last sentence muddies the idea that the issue resides solely with the cable and gives the impression that other "devices" would work fine using it.

351199f 👍 1 Answered DD. The issue is with the Charging Port. Since A & B don't make any sense in this situation, and the cable works with other devices, the answer must be D. and lie with the dirtiness of the device's port.

acf9805 👍 1 Answered C5. C — The cable is failing and needs to be replaced 🧸 Lightning should work either way. If flipping it fixes it, part of the cable/connector is failing.

Elle 👍 1 Answered DThe cable works with other devices if the Dave type so the port needs to be inspected and cleaned.
