Question

The battery life on an employee's new phone seems to be drastically less than expected, and the screen stays on for a very long time after the employee sets the phone down. Which of the following should the technician check FIRST to troubleshoot this issue? (Choose two.)

  • AScreen resolution
  • BScreen zoom
  • CScreen timeout
  • DScreen brightness
  • EScreen damage
  • FScreen motion smoothness

Why each option

The reported issues of drastically reduced battery life and the screen staying on too long point directly to excessive power consumption by the display, making screen timeout and brightness the primary culprits.

AScreen resolution

Screen resolution affects how clear images appear but typically has a negligible impact on battery life compared to brightness and timeout settings.

BScreen zoom

Screen zoom modifies the size of on-screen elements for accessibility, which does not directly cause significant battery drain or affect how long the screen stays on.

CScreen timeoutCorrect

Screen timeout settings determine how long the screen remains active after user interaction; a long timeout directly contributes to increased battery drain and the screen staying on for extended periods.

DScreen brightnessCorrect

Screen brightness significantly impacts battery consumption, as a brighter screen requires more power, directly leading to reduced battery life.

EScreen damage

Screen damage is a physical issue and would not inherently cause reduced battery life or an extended screen timeout unless it led to a hardware malfunction affecting power management, which is less direct than C and D.

FScreen motion smoothness

Screen motion smoothness (refresh rate) can impact battery life, but a new phone's screen staying on for a "very long time" and general "drastically less" battery life are more directly attributed to timeout and brightness settings first.
