220-1202 Practice Question: That their Android phone is running slowly and…
A user reports that their Android phone is running slowly and the battery drains quickly. They have many apps installed. Which built-in Android feature should you use to identify and stop a misbehaving app that is consuming excessive CPU and battery resources?
⚠ Common exam trap
CompTIA often tests the misconception that third-party task killers or developer options are appropriate troubleshooting tools, when in fact Android's built-in Battery Usage menu is the correct, non-destructive method to identify resource-hungry apps.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Check the Battery Usage menu in Settings to see which app is using the most power.
The Battery Usage menu in Android Settings (Settings > Battery > Battery Usage) provides a breakdown of power consumption by app and system component, letting you identify an app that is draining the battery or consuming excessive resources. From this screen you can select the offending app and force stop it, or open its App Info page to clear its cache or uninstall it. This is the correct built-in, non-destructive way to diagnose and stop a resource-hungry app without third-party tools or a factory reset.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use a third-party Task Killer app to automatically close background processes.
Why it's wrong here
Third-party task killers are generally discouraged on modern Android because they can interfere with normal system processes and often don't solve the root cause; the built-in tools are more effective.
- ✓
Check the Battery Usage menu in Settings to see which app is using the most power.
Why this is correct
The Battery Usage menu in Settings attributes power drain to individual apps, exposing the misbehaving process consuming excessive CPU. This directly satisfies the stem's requirement to identify the culprit before stopping it, since Android's per-app consumption data pinpoints the offender rather than merely showing overall battery level.
- ✗
Perform a factory reset from the Recovery Mode menu.
Why it's wrong here
A factory reset is a last-resort measure that erases all data; it is not the first step to diagnose a specific misbehaving app.
- ✗
Enable Developer Options and increase the background process limit.
Why it's wrong here
Increasing background process limits can actually worsen battery drain and does not help identify the offending app.
