For example, on laptops, you can change the advanced settings when your device is running on battery or plugged in, but on desktop PCs, you can only configure settings when your device is connected to AC power (for obvious reasons). It's worth noting that not every computer has the same available settings, it'll depend on your hardware configuration and device category. Wi-Fi adapters can use a significant amount of battery, as such it's also a good idea to check the Wireless Adapter Settings to make sure "Power Saving Mode" is set at least to Medium Power Saving.

Depending on how you use your computer, to reduce power usage, you can set exactly when your computer should go to sleep or hibernate using the Sleep settings. Usually, when you're not actively using your device, it'll automatically go into a low-power sleep or hibernation state. You may want to specify when to turn off the drive to conserve battery using the Hard disk settings. In the case your laptop is using a traditional hard drive. If you're looking to create a power plan to optimize battery life, you should consider changing the settings that can impact battery, including the brightness, dimming, and timeout under the Display settings.
