A corporate user reports that their smartphone battery depletes much quicker than expected, even with minimal use. Assuming all settings for display brightness and background app refresh are optimized, which of the following should a technician investigate NEXT to diagnose the battery drain?
Upgrade the mobile device to the latest operating system
Increase the device's screen timeout duration
Check for energy-consuming apps recently installed
Modify the device's performance settings to enhance battery life
Examining recently installed apps is prudent because some might run unnecessary background processes that drain the battery significantly. Display settings and background app refresh have already been optimized, so they are less likely to be the primary cause of the issue now. Checking for OS updates might resolve some issues, but it's less likely to be directly related to sudden battery drain compared to rogue applications. Performance settings typically impact processing power and speed rather than directly affecting battery life, making them a less likely cause in this situation.
