The battery life of Windows laptops has never been excellent, at least without making any settings. But with these tips, your laptop can easily run 24/7 – no longer have to look for power outlets everywhere.

5 Check your GPU settings

The independent graphics card consumes much more power than the integrated graphics card. This is one of the reasons for the performance improvements in gaming, but it also greatly reduces battery life. If your laptop supports MUX switches or allows disabling discrete graphics cards, turning on this feature will significantly extend battery life.

Some notebooks offer two GPU modes: hybrid mode and integrated mode. In hybrid mode, both graphics cards work at the same time, which is also the default operation method of most laptops with independent graphics. Integrated mode is very useful if you want to extend battery life, as it turns off the discrete graphics card, which greatly saves power.

Of course, this can lead to performance degradation when running games or other programs that rely on standalone graphics cards. However, due to the reduction in overall power consumption of the system, the battery life time will increase significantly. Take my HP Omen Transcend 14 as an example, with integrated mode enabled, it can last up to six to seven hours, while it only lasts about four hours in hybrid mode.

How to turn off the discrete graphics card and whether it supports this feature depends on the brand and model of your laptop. Not all laptops equipped with discrete graphics cards have this feature, especially entry-level gaming laptops. If you have high requirements for battery life, be sure to confirm that the device supports this function when purchasing.

4 Turn off unnecessary system services

Next are some Windows system optimization operations, which can not only improve battery life, but also enhance the overall system response speed. As we all know, Windows will run a large number of services in the background, and not all services have practical significance for daily use.

You can disable some non-essential services to improve battery life, such as: Windows Search Index Service, Connected User Experiences and Telemetry Service, and Backend Intelligent Transmission Service (BITS).

Turning off these services has little impact on system functions, but it can release more system resources and improve performance - after all, those functions that you do not use often will no longer occupy CPU and memory. In addition, some adjustments will help enhance Windows 11's privacy protection capabilities.

3 Check the laptop performance mode

Most high-performance laptops are equipped with manufacturer-owned control software that includes multiple performance or power modes. These modes are essentially different power profiles that regulate power consumption of the CPU and GPU. Switching to low power mode can reduce performance, but can significantly increase battery life.

The settings of notebooks of different brands and models vary, but manufacturers usually pre-install tools such as Omen Gaming Hub, MSI Center, Dell Power Manager, Lenovo Vantage, etc., to facilitate users to quickly adjust the power mode.

These tools usually automatically switch to energy-saving mode when battery powered by default. However, in order to maximize battery life, manually checking and confirming that the current performance mode is still a recommended operation.

The Windows system itself also has three power modes built-in:

• Best Performance : Provides the strongest performance, but with the highest power consumption.
• Balanced mode : Get a compromise between performance and power consumption.
• Optimal energy efficiency : Maximize CPU and GPU power consumption and extend battery life.

Generally, the balance mode is sufficient for daily tasks, and even light gaming is stress-free, depending on the hardware configuration. If you are pursuing ultimate battery life, please select the "Best Energy Efficiency" mode. It should be noted that the system will run slightly slow at this time.

You can also set Windows to automatically switch power plan when plugging in or using the battery. The steps are as follows:

1. Open Windows Settings and go to System > Power and Battery .
2. Expand the Power Mode option to set the power mode in plug-in and battery states respectively.

In addition, Windows will automatically enable the energy-saving mode when the power drops between 10% and 50%, reducing energy consumption by turning off some background services. You can set the trigger conditions yourself.

2 Adjust screen brightness and RGB lighting

If your laptop comes with an OLED screen or RGB lighting effect, be sure to turn them down or turn them off when using the battery. The power consumed by screen brightness, keyboard backlight and other RGB lighting is far beyond your imagination.

The most effective way is to turn the screen brightness to the lowest available level and turn off all RGB lighting effects completely, including keyboard backlighting. If the backlight cannot be turned off completely, at least set to a single static color and adjust to the lowest brightness. While the cool key-by-key RGB lighting is attractive, it is quietly swallowing up your battery life.

There are differences in the setting method and adjustable options for notebooks of different brands and models. The relevant controls are usually integrated in the management software provided by the manufacturer and can be set together with the power mode.

1 Make good use of Windows power settings

In addition to power mode, Windows also offers other power management options to help you further extract battery potential. For example, the Screen and Sleep setting can automatically turn off the screen after no operation for a period of time to save power. The setup method is as follows:

1. Enter Windows Settings and click System > Power and Battery .
2. Expand the screen, sleep and sleep timeouts , and customize the shutdown time based on plug-in or battery status.

In addition, more advanced power settings are hidden in the control panel, which allows fine control of the power supply policies of each hardware component. The operation path is as follows:

1. Open the control panel and select the power option .
2. Click Change Plan Settings next to the current power plan.
3. Click to change advanced power settings .

This menu contains a lot of technical options. If you are not sure about its function, here are some of the most critical setup suggestions:

• Processor Power Management : Set the minimum processor state in battery state to 5%.
• USB selective pause : Allows idle USB devices to stop power supply, suitable for users who often connect to peripheral devices (such as mouse and keyboard).
• PCI Express - Link State Power Management : It is recommended to set to medium energy saving .

Depending on the battery capacity and health status, combined with the above settings, an additional hour of battery life can usually be extended. By configuring Windows 11's multiple power options, you can easily achieve worry-free mobile office work and no longer frequently look for charging opportunities.
