Phone battery technology has come a long way, but anxiety about running out of power is still common. Here are four ways to help preserve your phone’s battery life. Turn On Power Saving Mode Phones are equipped with a variety of power-saving modes that selectively deactivate or reduce certain functionalities. These settings serve to conserve battery life in instances where charging is not immediately possible. Reduce Screen Brightness Lowering screen brightness can significantly improve your battery life. Try setting it as low as is comfortable for your eyes or turning on your device's auto-brightness setting. Connect To Wi-Fi A weak cell signal can cause your device’s battery to drain faster because it uses more power to maintain a signal. Try connecting to Wi-Fi when possible to conserve battery in areas with weak cellular signal. Avoid Extreme Temperatures If it is extremely cold or hot, your battery will suffer. So avoid leaving your phone in direct sunlight on hot summer days.
