    1

    Turn down screen brightness

    ~16s
    Your screen is the biggest battery drain. Swipe down from the top of your screen (Android) or swipe down from the top-right corner (iPhone) to open the control panel. Drag the brightness slider to about 40-50%. Enable "Auto-Brightness" so your phone adjusts automatically based on lighting.

    Turn off WiFi and Bluetooth when not needed

    ~15s
    When you leave your house, turn off WiFi so your phone stops searching for networks. If you are not using wireless headphones or a smartwatch, turn off Bluetooth too. Both drain battery in the background.
    3

    Close background apps

    ~24s
    Apps running in the background use battery even when you are not looking at them. On iPhone: swipe up from the bottom and swipe away apps. On Android: tap the square button and swipe apps away. You do not need to close every app, just the ones you are done with.

    Quick Tip

    Your phone is smart about managing background apps. Focus on closing navigation, streaming, and social media apps — these use the most battery.

    4

    Enable Low Power Mode

    ~15s
    When your battery drops below 20%, turn on Low Power Mode. iPhone: Settings > Battery > Low Power Mode. Android: Settings > Battery > Battery Saver. This reduces background activity, mail fetch, and visual effects to stretch your remaining battery.
    5

    Check which apps drain the most battery

    ~16s
    iPhone: Settings > Battery shows which apps used the most battery in the last 24 hours or 10 days. Android: Settings > Battery > Battery Usage. If an app you rarely use is near the top, consider uninstalling it or restricting its background activity.
