Summary: What Best Performance, Balanced, and Best Power Efficiency actually do in Windows 11, where the classic power plans went, and which settings to pick for laptops and desktops.

## The Problem
Windows 11 has a **Power mode** setting, an **Energy saver** setting, classic **power plans** that may or may not be visible, and often a separate app from your laptop manufacturer that does something similar. They overlap, and it is not obvious which one is in charge.

This guide explains what each one controls, which settings actually change performance and battery life, and what to choose for your situation.

## The Short Answer
* **Desktop:** Power mode **Best performance**. Leave everything else at default.
* **Laptop on the charger:** **Best performance** or **Balanced**.
* **Laptop on battery:** **Balanced**, with **Energy saver** turning on automatically at 20%.
* **Gaming laptop:** set the mode in the manufacturer's app (Armoury Crate, Lenovo Vantage, Alienware Command Center, and so on) — it usually overrides Windows.

## Power Mode: The Main Setting
**Settings** → **System** → **Power & battery** → **Power mode**.

| Mode | What it does |
|---|---|
| **Best power efficiency** | Lets the CPU run at lower clock speeds and power limits. Quieter and cooler, noticeably slower under load. |
| **Balanced** | Boosts the CPU when you need it and drops back quickly. The right choice for most people most of the time. |
| **Best performance** | Keeps clock speeds higher and responds to load faster. More heat, more fan noise, less battery. |

On laptops, you get a separate setting for **Plugged in** and **On battery**. The difference between modes is largest on laptops; on desktops, Balanced and Best performance often measure within a few percent of each other.

## Energy Saver (Formerly Battery Saver)
**Settings** → **System** → **Power & battery** → **Energy saver**.

Energy saver goes further than a power mode: it limits background activity, reduces screen brightness, pauses some sync, and on many systems caps CPU performance. Browsers also detect it and may reduce video frame rates — a common cause of [choppy video in the browser](https://www.mytechnician.tech/tips/fix-youtube-video-lag-stuttering-browser/).

Set **Turn energy saver on automatically** to **20%** rather than **Always**, unless you are trying to get through a long day away from a charger.

## Where Did the Classic Power Plans Go?
The **Balanced**, **High performance**, and **Power saver** plans still exist in **Control Panel** → **Hardware and Sound** → **Power Options**.

On many newer laptops, you will only see **Balanced**. That is expected: PCs that use **Modern Standby** (S0 low-power idle) hide the other plans, and Power mode replaces them. You can check which sleep states your PC supports by running this in Terminal:

```
powercfg /a
```

If you see **Standby (S0 Low Power Idle)**, the power mode slider is the intended control. Forcing old plans onto these systems is not recommended — it can break sleep.

### Ultimate Performance
Windows includes a hidden **Ultimate Performance** plan designed for workstations. It stops the CPU and other hardware from entering low-power states. To add it on a desktop, run in **Terminal (Admin)**:

```
powercfg -duplicatescheme e9a42b02-d5df-448d-aa00-03f14749eb61
```

Then select it in **Power Options**. It is worth trying on a desktop used for gaming or rendering. It is **not** worth using on a laptop — it drains the battery and makes the laptop hotter for very little gain.

## Settings Worth Changing
These live in **Power Options** → **Change plan settings** → **Change advanced power settings** for the active plan.

* **USB settings → USB selective suspend:** set to **Disabled** if USB devices disconnect randomly, which is common with audio interfaces and some mice. See also [USB device not recognized](https://www.mytechnician.tech/tips/fix-usb-device-not-recognized-windows-11/).
* **PCI Express → Link State Power Management:** set to **Off** on desktops if you get stutters or GPU wake problems. Leave it on for laptops.
* **Processor power management → Maximum processor state:** setting this to **99%** on battery disables CPU boost on many laptops. It runs slower but much cooler — useful when a laptop is too hot on your lap.
* **Power buttons and lid → Lid close action:** choose **Do nothing** if you use a laptop closed with an external monitor.

## Settings to Leave Alone
* **Minimum processor state at 100%.** This used to be a gaming tip. On modern CPUs it mostly increases heat and power use without improving performance.
* **Hard disk → Turn off hard disk after** on an SSD-only PC. SSDs manage their own power.
* **Disabling sleep entirely** to fix a sleep problem. Fix the cause instead: [fix sleep and hibernation](https://www.mytechnician.tech/tips/fix-sleep-hibernation-not-working-windows-11/).

## Useful Reports
Windows can generate detailed reports about power use:

* **Battery report** — design capacity vs current capacity, charge history. Run `powercfg /batteryreport` and open the HTML file it saves. More detail in [check laptop battery health](https://www.mytechnician.tech/tips/how-to-check-laptop-battery-health-windows-11/).
* **Energy report** — a 60-second trace of power problems such as devices that prevent sleep. Run `powercfg /energy` in Terminal (Admin).
* **Sleep study** — on Modern Standby laptops, `powercfg /sleepstudy` shows what drained the battery while the lid was closed.

## Manufacturer Apps
Laptop apps like **Lenovo Vantage**, **Dell Optimizer**, **HP Command Center**, **ASUS Armoury Crate**, and **MSI Center** add their own performance or thermal modes. These often change fan curves and power limits directly in the firmware, so they have a bigger effect than the Windows power mode.

If the Windows setting seems to do nothing, check the manufacturer app — it is usually the one in charge. Use **one** of them to make changes and leave the other on its default, so the two are not fighting.
