E. Lower the screen brightness
Answer
E. Lower the screen brightness
Explanation
Screen brightness is one of the biggest battery drains on mobile devices.
Screen brightness is consistently identified as one of the largest contributors to battery drain on mobile devices. Reducing the display brightness immediately decreases power consumption, often resulting in a noticeable improvement in battery life. According to leading tech sources, lowering the brightness setting is a quick and effective solution that works across all smartphone models and operating systems. This adjustment is recommended before making other changes, as the display typically uses more energy than any other component, especially on modern devices with large, high-resolution screens.
Additional steps, such as enabling power-saving mode or adjusting screen timeout, can further help, but lowering screen brightness is the most impactful and straightforward first action to take for extending battery life.
