Windows 10 comes with a nice feature to create a system sleep diagnostics report. Using the data provided in that report, you can get a lot of useful information about intervals when the system was idle for the last three days, and learn how the operating system entered the sleep state.
Windows 10 allows the user to create a special report which shows battery usage in detail. It can be done without third-party tools. The only application you need is the built-in console tool "powercfg".
Modern Windows versions come with a nice feature to create a power efficiency report. It will help you to see statistics about your power configuration with a detailed report.
By default, Windows 10 come with three power plans: High Performance, Balanced, and Power Saver. These plans are designed to quickly let you switch a group of hardware and system power settings (like display, sleep, etc). Your PC can have additional power plans defined by its vendor. These power settings affect how long your battery lasts and how much power your PC consumes. It is possible to customize these power plan settings but it requires too many clicks to get there. If you change these settings often, you can use a special command to directly open them.
In Windows 8, Windows 7 and earlier, you can choose from predefined power plans which are a group of several power-related settings. If you are running a laptop on battery, you can choose the "Power Saver" plan. If you are running a desktop PC which is on AC power, you can set the "High Performance" plan. To switch the power plan, Windows gives you only two options if you use the notification area power icon. One of them is always the "Balanced" plan. This is not ideal because you have to open the Control Panel and go to Control Panel\System and Security\Power Options to access all the available power plans. Today, we will show you how to save your time and switch the power plan directly from the command line or with a shortcut so you don't need to open Power Options Control Panel every time.
