The main reasons and solutions for fast battery consumption of Windows computers: 1. Too many background programs, close unnecessary self-start programs and high resource-occupying applications, especially multi-tab pages of the browser; 2. High screen brightness and external devices affect, lower brightness, enable automatic adjustment and unplug unnecessary peripherals; 3. Improper power mode setting, switch to "energy-saving" mode or custom power plan; 4. Battery aging or hardware problems, check the battery health status through commands, update the driver if necessary or contact after-sales inspection.

Windows computers consume fast battery power, and the reasons are actually quite common. If you find that the battery is dropping much faster than before, it is likely that the battery is not broken, but that there is something wrong with the system settings, software behavior or hardware usage.

Too many background programs, quietly consuming power

Many programs run in places you can't see, such as the browser has more than a dozen tabs, cloud synchronization tools, instant messaging software, etc. They will continue to occupy CPU and network resources, resulting in faster battery consumption.

• Open the task manager (Ctrl Shift Esc), switch to the "Startup" tab, and see which programs start up automatically and turn off unnecessary ones.
• Check the programs with high CPU, memory and disk usage in the "Process" page and close them appropriately.
• Pay special attention to browsers like Chrome. The more tabs the more power you consume.

You can go to "Settings > System > Battery", click "Battery Usage" to see which application consumes the most power in the last 24 hours or the past week.

Screen brightness and connected devices also have a great impact

The screen is one of the most power-consuming components of a laptop. Many people are used to adjusting the brightness to the highest level, which will naturally cost more electricity.

• Turn down the brightness, or turn on the automatic adjustment function.
• Shorten the screen sleep time and can be adjusted in the Power and Sleep settings.

In addition, external devices such as Bluetooth headsets, USB flash drives, mouse, etc. will also increase power consumption:

• Unplug or disconnect when not in use.
• Turn off unused wireless functions, such as Wi-Fi, Bluetooth, location, etc.

If the power mode is not selected correctly, the performance will damage the battery if it is preferred.

By default, Windows may be in "high performance" or "balanced" modes. In order to ensure a smooth experience, these two modes will make the CPU more active and naturally consume more power.

• Switch to "Energy Saving" mode: click the battery icon in the lower right corner and select "Energy Saving".
• High-performance mode is suitable for plug-in use, and try to avoid it when working in mobile office.

You can also customize the power plan, such as shortening the hard disk shutdown time, reducing the maximum operating status of the processor, etc. These details can effectively extend battery life.

Battery aging or other hardware problems cannot be ignored

If your laptop has been used for more than two or three years, the battery capacity may have dropped a lot.

• Run powercfg /batteryreport at the command prompt and a battery report will be generated to view the gap between "design capacity" and "current full capacity". If the difference is much, the battery is aging.
• If the battery is healthy but still consumes power very quickly, it may be that the driver is incompatible or the motherboard is powered abnormally, you can try to update the driver or contact after-sales inspection.

Basically these common reasons. Pay more attention to background programs and power settings in daily life, and the battery life should be significantly improved.
