Extend your phone’s battery life by adjusting its display settings. On an iPhone, go to Settings > Display & Brightness and turn on ‘Auto-Brightness’ to allow your phone to adjust its screen brightness based on the ambient light. You can also turn on ‘Low Power Mode’ to conserve battery when you’re running low. On an Android phone, go to Settings > Display and turn on ‘Adaptive Brightness’ to adjust your screen brightness based on the ambient light. You can also turn on ‘Battery Saver’ mode to limit background activity and save power. These small adjustments can help extend your phone’s battery life and keep it running longer throughout the day.
