How do I extend the battery life of my HUAWEI laptop?

Methods for improving battery life

1. If the battery power decreases too fast, press Alt+Ctrl+Del, and select Task Manager to check whether there are abnormal apps. End unused high-usage apps, and check whether the CPU usage is normal (no more than 10%). Generally, the CPU usage fluctuates below 5% or even stays about 1% when the computer is idle.
   

   If this is the first time you open Task Manager, see Opening or hiding the Processes tab in the Task Manager Window.

   

2. Start Windows updates after connecting your computer to a power adapter, as Windows updates will cause continuous high power consumption.

   To reduce power consumption caused by Windows updates in battery power supply mode, right-click the Start button , and go to Settings > Windows Update to check whether a Windows update is available. If a new version is available, back up your data and install the update.

   

3. Set the display brightness to no higher than 60% when you use the computer indoors. Decreasing the brightness can effectively improve the battery life.

   To set the brightness, right-click the Start button and go to Settings > System > Display.

   

4. Update the drivers on your computer in a timely manner once Huawei PC Manager pushes a driver update notification. New drivers usually help improve battery life. Open Huawei PC Manager, and go to Optimization > Drivers > CHECK to update the drivers.

   

5. Use the default power mode, or select Best power efficiency to improve the battery life.

   

6. Enable Battery saver, which can maximize battery life but will reduce the display brightness and CPU performance.

   

7. Remove external devices in a timely manner. If you do not need to connect the computer to an external device such as a docking station, removing the external device can reduce power consumption.
8. Some intensive apps, including games (such as League of Legends and CrossFire), video editing apps (such as Corel VideoStudio), and design apps (such as VS and CAD), consume a lot of power. It is recommended that you connect your laptop to a power supply when using these apps, because using them while in battery mode will consume more battery power.

Methods for minimizing power consumption in the screen-off standby state (Screen-off/Sleep/Hibernation/Power-off mode)

1. Screen-off: In this mode, the monitor is turned off, but the system still consumes the battery power. In normal cases, the computer automatically turns off the screen when it is idle for a certain period of time (4 minutes by default).
2. Sleep: The computer automatically enters Sleep mode after being idle for a certain period of time (4 minutes by default). In this mode, the computer still consumes a little power. If some apps continuously occupy the audio channel, the computer will not be able to enter sleep. It is recommended that you check the usage of each channel once the power consumption is abnormal in the screen-off state. As shown in the following figure, run the powercfg requests command to check whether there are audio streams that prevent the computer from entering Sleep mode.

   Method: Enter CMD in the search box in the lower left corner of the computer screen, (or right-click the Start button in the lower left corner of the computer screen, select Search, and enter CMD in the displayed search box), right-click Command Prompt, and select Run as administrator. In the displayed window, enter powercfg requests at the cursor position and press Enter.

   

   When the system enters Sleep mode, it may be woken up by scheduled tasks. You can check whether there are scheduled tasks in the system.

   Method: Enter CMD in the search box in the lower left corner of the computer screen (or right-click the Start button in the lower left corner of the computer screen, select Search, and enter CMD in the displayed search box), right-click Command Prompt, and select Run as administrator. In the displayed window, enter powercfg waketimers at the cursor position and press Enter.

   

3. Hibernation: A computer in Sleep mode will enter Hibernation mode when the timeout period (3 hours by default) has passed, or when the power consumption threshold (2% by default) is surpassed. In Hibernation mode, the power consumption is low, and the device will not be woken up by scheduled tasks. To manually enter Hibernation mode, select to show Hibernate in Power menu, and set When I close the lid to Hibernate.

   To show Hibernate in Power menu, enter Control Panel in the search box in the lower left corner of the computer screen (or right-click the Start button in the lower left corner of the computer screen, select Search, and enter Control Panel in the displayed search box), open it, and go to Hardware and Sound > Power Options.

   

4. Power-off: If you will not be using your computer for an extended period of time, it is recommended that you power it off to save power.
