Simplify Your Workflow: Closing Apps, and Using Airplane Mode

On the other hand, if you’re writing a novel or playing a local video file and don’t need to be distracted by notifications, it’s fine to enable Battery Saver. It’s a good habit to adjust your laptop use in more battery-conserving ways, such as by sticking to one app at a time and closing everything else when you’re not using it. It’s a bit like turning off the lights when a room is vacant. If you’re going back and forth between the kitchen and the pantry all the time, or between Firefox and Word, by all means keep both sets of lights and apps on and open. But if you’re just cooking or watching a YouTube video, you’ll be best served by turning off and closing everything else.

In addition to aiming to single-task, consider enabling Airplane mode in Windows, or turning off Wi-Fi and Bluetooth in macOS if you know you’ll be editing a document with no need for web access. In addition to eliminating distractions, Airplane mode eliminates a significant source of battery drain: not only the wireless radios themselves, but also the background apps and processes that constantly use them, such as updaters and push notifications.
