Windows 10 includes a “Battery Saver” mode that’s designed to extend your laptop or tablet’s battery life. Windows will automatically enable Battery Saver when your PC’s battery runs low, but you can control this–and choose exactly what Battery Saver does.
Battery Saver mode is front-and-center on Windows 10, pushing power plans to the background . Rather than fiddle with power plans, Microsoft would prefer you just use Battery Saver mode and stick to the default Balanced power plan.
You can turn Battery Saver mode on whenever you like. To do so, just click or tap the battery icon in the notification area on your taskbar. Click or tap the “Battery saver” tile to activate or deactivate it. While Battery Saver mode is enabled, you’ll see a little green leaf superimposed on the battery icon.
This option is one click away from the battery icon, just as the “Power Saver” power plan was on Windows 7 and Windows 8. It’s clear Microsoft would rather you use this instead of messing with those old and confusing power plans.
