CompTIA A+ Core 1 (220-1101) — Question 552

A user's mobile phone gets really hot to the touch and does not retain a charge. The user also reports that the phone is very slow, especially while charging.
Which of the following is MOST likely causing these symptoms?

Answer options

• A. Broken charging port
• B. Digitizer failure
• C. CPU overheating
• D. Defective battery

Correct answer: D

Explanation

The symptoms of overheating, inability to hold a charge, and reduced performance while charging strongly indicate a defective battery, which can cause excessive heat and diminished functionality. While a broken charging port or CPU overheating may contribute to performance issues, they do not directly explain the combination of heat and charging problems like a defective battery does.
