Question
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?
Options
- ACheck the applications and their resource usage.
- BOrder a replacement battery and see if the phone maintains its charge.
- CConfigure the email software to work on a fetch schedule instead of the push setting.
- DWipe the phone entirely and reset all settings to their default states.
- EDecrease the screen brightness to 30%.
- FUninstall all the applications on the phone and see if the battery issues remain.

Explanation
The first diagnostic step should always be to identify the root cause before taking any corrective action. Since the user recently installed several applications and the phone is otherwise new and high-end (ruling out hardware age as an obvious cause), checking application resource usage via the battery settings is the logical first step. A rogue or poorly coded app may be running background processes, using GPS, or keeping the CPU/screen active unnecessarily. Ordering a replacement battery (B) is premature without diagnosis. Configuring email fetch vs. push (C), wiping the phone (D), lowering brightness (E), and uninstalling all apps (F) are all interventions that skip the diagnostic step and could be unnecessary.
