A sales representative is driving to visit several customer sites in the city. The representative notices that the smartphone is draining battery power more quickly than normal. What is a possible cause of the issue?
- The battery charger is malfunctioning.
- The smartphone was not fully charged.
- There are not enough Wi-Fi access points in the area.
- The smartphone is roaming among cell towers.
Explanation: When a mobile device is roaming among cells, the battery consumption is increased because the device needs to detect and negotiate with cell towers for connections. What the user experienced here is relative to the normal use. Thus, the issues of whether the device is fully charged and the condition of the battery charger are irrelevant.
