Adjust your power settings

You can adjust the power settings on your device to help save power. To do this:

• Go to the Windows Start menu
• Type power settings and press Enter
• Click on the Edit power plan option

• Review the available power plans and select one that balances performance and power consumption, or create a custom power plan to fine-tune the settings to your needs
• Modify the settings for your chosen power plan as desired
• Click Save changes to apply your modifications

Turn off unnecessary features

There are several features in Windows that can use power, such as the touchscreen, the Wi-Fi adapter, and the Bluetooth adapter. If you are not using these features, you can turn them off to save power.

• Go to the Windows Start menu
• Type device manager and press Enter
• Click on the Device Manager option
• Locate the category that contains the device you want to disable (such as Human Interface Devices for the touchscreen)

• Expand the category by clicking on the arrow to the left of the category name
• Right-click on the device you want to disable and select Disable
• Click Yes to confirm the action
• The device will be disabled and will no longer be available for use
• You can go back and click Enable device anytime

Use hibernation or sleep mode

When you are not using your device, you can put it into hibernation or sleep mode to save power. Hibernation saves the current state of the system to the hard drive and shuts down the device, while sleep mode puts the device into a low-power state while maintaining the current state in memory. To enable hibernation or sleep mode:

• Go to the Windows Start menu
• Type power settings and press Enter
• Click on the Choose what the power buttons do option

• Review the current power button settings and modify them as desired
• Click Save changes to apply your modifications

You can use these steps to enable or disable hibernation or sleep mode, or to specify different actions for the power button depending on whether the device is plugged in or running on battery power.

Fix underlying system issues

It is not specifically designed to improve battery life, but it can potentially help by fixing any underlying issues that may be causing your device to use more power than it should.

For example, if your device is experiencing problems with its operating system, registry,[ref en-1] or has corrupted system files that cause BSODs,[ref en-2]  it may be using more power than it should. Reimage PC Repair can help by repairing these issues and restoring your system to its optimal state, as well as clearing cookies and cache[ref en-3] which may in turn help improve the overall performance and efficiency of your device.

Turn off your device when not in use

If you are not using your device for an extended period of time, it can be a good idea to turn it off to save power. This can be especially helpful if you are using a device with a battery that is not fully charged.

Keep your device cool

Keeping your device cool can help save power, as heat can drain the battery and reduce the overall efficiency of the system. You can help keep your device cool by avoiding high temperatures and using a cooling pad or fan if needed.
