- A
The battery is completely dead and needs replacement
Why wrong: A dead battery would not prevent the phone from showing a charging indicator when connected to power; the phone should at least show a low battery icon.
- B
The Lightning port is clogged with debris
Debris in the port can prevent the connector from making full contact, stopping charging even with a working cable and adapter.
- C
The operating system is corrupted
Why wrong: A corrupted OS would typically cause boot loops or other system issues, not specifically prevent charging.
- D
The phone's wireless charging coil is damaged
Why wrong: A damaged wireless charging coil would not affect wired charging through the Lightning port.
Quick Answer
The answer is a clogged Lightning port, as the user has already ruled out the cable and adapter by trying different ones, which isolates the fault to the device itself. On the iPhone 13, debris or lint compacted deep inside the Lightning port can physically block the connector from making full contact with the charging pins, preventing any power transfer even though the screen and buttons function normally. This scenario directly tests your ability to apply the CompTIA A+ troubleshooting methodology—specifically, eliminating external variables before inspecting the hardware interface. A common trap on the 220-1201 exam is jumping to a battery or logic board failure when the user reports “iPhone not charging with different cables and adapters,” but the correct first step is always to inspect the port with a flashlight. Remember the mnemonic “P.I.C.”—Power source, Interface, Cable—and when the cable and adapter are cleared, the Interface (the port) is the culprit.
220-1101 Mobile Devices Troubleshooting Practice Question
This 220-1201 practice question tests your understanding of mobile devices troubleshooting. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A user reports that their iPhone 13 will not charge when plugged into the charging port. The user has tried different cables and power adapters, but the phone still does not charge. The phone's screen and buttons work normally. Which of the following is the most likely cause?

Correct answer & explanation
The Lightning port is clogged with debris
Since the user has already ruled out the cable and adapter, the issue is likely with the phone itself. A common problem is debris or lint compacted in the Lightning port, preventing a proper connection. Cleaning the port carefully can often resolve this.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 220-1201 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
