[Windows 11/10] Troubleshooting - Short Battery Life (Rapid Battery Drain)
Applicable Products: Notebook, Gaming Handheld
Li-ion batteries used for electronic products are consumable products. Due to the chemical properties of Lithium ions, the battery capacity will decrease by use over time, the user’s environment, and behavior. Therefore, you may experience that the battery life is not as expected, but that is a normal occurrence. Here you can learn more about ASUS Battery Information Center.
Except for the battery aging effect, the battery discharge rate will also depend on the device’s software operations or system power management settings. For example, running computation-heavy programs, such as graphics software, gaming software, and video playing, it will speed up the battery consumption and even some applications may continue working in the background that may occupy the resource and battery life.
If you’re noticing your battery life deteriorating or not performing as expected, this article will provide useful advice on how to fix common battery life issues.

- In [Diagnosis Tool]④, click [Battery problems]⑤. Here you can learn more about MyASUS System Diagnosis - Introduction.
- Connect the device to power and click [Checkup]⑥.
- After the check, click [Results]⑦. If any error occurs, it usually means your device’s battery may require action. Please contact ASUS Product Support to replace the battery.
If no issue found, it means the battery health is good, but maybe there are some applications, software, or system settings causing the increased battery consumption. Please refer to the next steps to optimize the system settings and check the battery discharge of applications.
Optimize the setting for maximizing battery life
Optimize Windows system settings
Try to adjust below system settings to save battery power.
- Reduce the quantity of the running applications: All applications consume memory and power, even when minimized or running in the background, which may affect your device's battery performance. To decrease the battery consumption, please close all unnecessary applications. You can do so via Windows Task Manager: How to use Task Manager to check system performance.
- Reduce the screen brightness: Reduce the screen brightness is an effective way to increase the battery life.
- Turn off the keyboard backlight: Turning off the keyboard backlight also helps save battery power.
- Remove non-used peripherals: External devices also consume battery power, even if they are not in use. Please disconnect unnecessary peripherals (both wired and wireless) to save battery power.
- Disable Wi-Fi/Bluetooth function: When you are not using Wi-Fi or Bluetooth connections, please turn them off to save battery power.
- Change power plan: Go to the Power Options menu in Windows Settings and select ASUS Recommended power plan. This will automatically balance performance with energy consumption. If this plan is not available on your device, please select Balanced. To learn more about changing Power mode and plan, visit the following article: Change Power mode and plan.
