1: Charge your laptop fully before college ! (sorry, it's obvious and it doesn't help if you forgot today but it's true...)

2: If you havn't been able to charge fully or aren't confident it will last for a day - bring a charger!

3: Turn down the screen brightness

4: Close tabs and applications you aren't using

5: Watch less video (or lower the quality settings)

6: Avoid using power intensive applications when not connected to power (i.e. rendering a video or recording music will drain your battery much faster than word processing - Gaming between sessions is likely to have a big impact on battery life too)

7: Use wired headphones and turn off bluetooth when you don't need it.

8: Try using darker backgrounds and 'dark mode' on browsers

9: Try closing the device when you don't need it in class

10: Don't let your laptop get too hot (use on a hard surface where it can get proper airflow - using a laptop on a surface like a blanket can block the vents, cause it to get hot and damage battery) )
