Save Your Laptop Battery Use

For laptop users, Windows 10 comes with an official Battery saver feature for the first time, which you can find in the 'System' section of Settings (there's also an estimate of how long your battery is likely to last). You can turn the Battery Saver mode on or off manually, or have it kick in automatically when your battery gets down to a certain level. Click the 'Battery Saver' settings link to change this level from the default 20%, and to specify certain apps that are exempt from the various power-saving features.
