CompTIA A+ 220-1101 Practice Question
A user reports that their smartphone unexpectedly shuts down even though the battery indicator shows it is 30% charged. Upon a restart, the device shows a significantly lower battery percentage. The device is relatively new and the user hasn't reported any other issues. What is the most likely cause of the issue?
The device is overheating due to heavy usage or environmental factors.
The user is overusing power-intensive apps, draining the battery quickly.
The battery requires calibration to correctly display the charge level.
There is damage to the device's charging port preventing proper charging.
