Windows 10/8/7 has three main power plans. They are – High Performance, Balanced and Power saver. Each Power Plan has different settings and is meant for varying situations and target different uses. Switching between the plans offers trade-offs between Performance and Power consumption.
Power Plans in Windows 10/8/7
You can access the Power Plans by right clicking on the Power icon sitting in your Notification area of via the Control Panel > Hardware and Sound > Power Options.
For most users, it is the Balanced Power plan which may be suitable and is thus the default. Depending on the workload requirements, this plan configures Windows 7 to dynamically scale the level of performance.
The High-Performance power plan disables dynamic scaling of performance to match the workload and instead delivers constant high-performance levels at the cost of increased power consumption. This power plan is useful in certain scenarios that are highly performance or latency sensitive or in scenarios in which power consumption is not an issue.
Advantages of High-performance power plan
- The display is brighter.
- The computer operates at a very high level of performance.
Disadvantages of High-performance power plan
- There is the potential for more heat generation.
- Processor performance is not optimized during short idle periods.

The Power Saver power plan helps in maximizing energy savings. If you are using a Mobile PC or running on battery power, this plan helps in maximizing battery life.
Advantages of Power Saver power plan
- Battery life increases because of reduced power level.
- Screen brightness is reduced automatically.
- The CPU and hardware are set to aggressively take advantage of downtime.
