    Check your system preferences to see if something is running in the background. Your screen brightness may be too high. Your Mac might even be running after the screensaver comes on. There could be several reasons.

    Tips to improve battery life:
    1. Shut down Apps working in the background;
    2. Dim your screen. Press the F1 key and move the screen brightness down. You can also control this in System Preferences.
    3. Turn Bluetooth Off (or open System Preferences > Bluetooth and click Turn Bluetooth Off.
    4. Turn off Wi-Fi. This is a bit more extreme as you won’t be able to use wireless internet. But if you're not using the internet or email make sure you turn Wi-Fi off. Click AirPort in the Menu bar and choose Turn Wi-Fi off.
    5. Mute sound. Tap the Mute Sound button to get rid of any extraneous alerts and noise. You can turn sound on and off as you need to.
