CompTIA A+ Core 2 (220-1002) — Question 355

A user's mobile device is losing its battery charge very quickly. The user reports a 90% charge at 9:00 a.m., but has 22% battery by 1:00 p.m. The user has installed several applications, and the phone is a relatively new, high-end phone. The user claims most of the usage involves checking emails for a few minutes three or four times per hour.
Which of the following should a technician perform FIRST to diagnose the issue properly?

Answer options

• A. Check the applications and their resource usage.
• B. Order a replacement battery and see if the phone maintains its charge.
• C. Configure the email software to work on a fetch schedule instead of the push setting.
• D. Wipe the phone entirely and reset all settings to their default states.
• E. Decrease the screen brightness to 30%.
• F. Uninstall all the applications on the phone and see if the battery issues remain.

Correct answer: A

Explanation

The correct first step is to check the applications and their resource usage, as this can reveal if any app is consuming an excessive amount of battery. Ordering a replacement battery or wiping the phone may be premature without first identifying the cause. Adjusting settings like screen brightness or email fetch schedules could help, but understanding the resource usage is crucial for a proper diagnosis.
