If you’d like to get the most out of every battery charge, Windows 10 has a ‘Battery Saver’ feature for your laptop or tablet. This disables unnecessary background functions such as live tile updates and email and calendar syncing, and it can also auto-dim your screen brightness.
To operate the feature, you can find it by clicking on it in the Action Centre, or under System in Settings. You will also be able to see which of your apps are using up the most battery life.
