A user reports that their smartphone frequently overheats and the battery drains much faster than normal. After confirming that there are no software issues and the device is updated to the latest firmware, which of the following is MOST likely the root cause of the problem?
There is a large number of applications running in the background.
The device's screen brightness is set to maximum.
The charger being used is not the manufacturer's original charger.
The battery needs to be replaced due to degraded health.
Poor battery health is the most likely culprit for the reported issue. Smartphone batteries have a finite number of charge cycles and can degrade over time, leading to overheating and rapid power loss. This aligns with the symptoms described. The other options, although plausible in certain contexts, do not directly match the symptoms of rapid battery drain and device overheating that are often related to battery health.
