Suggested Answer: D Vote an answer

Comprehensive and Detailed Explanation From Exact Extract:
Background applications can significantly drain a smartphone's battery, even when the device is idle. A technician should first review which apps are running in the background and consuming power through the battery usage section of the OS. Disabling or restricting power-hungry apps often resolves poor battery life.
A: Storage usage doesn't significantly affect battery life.
B: End of software support is unrelated to battery performance unless it's causing inefficient processes, which would still be secondary.
C: Charger wattage affects charging speed, not battery life after charging.
