Optimizing Battery Life on Lenovo Legion Slim 5 Gen 8 Laptop

So I recently purchased a Lenovo Legion Slim 5 Gen 8 laptop with a Ryzen 7 7840HS processor and an RTX 4060 graphics card. While the battery life is already respectable, I want to maximize it as much as possible for college to avoid carrying around an extra USB-C charger. Here are the steps I have taken so far to achieve around 7 and a half hours of battery life:

  1. Disabled CPU Boost Mode using a registry update file that added a new entry in the Power setting management.
  2. Created a replica of the "Balanced" Power Plan called "Power Saver" with Boost off and changed the maximum processor state in advanced power settings to 30% while on battery.
  3. Enabled Battery Saver mode: Always on + Best power efficiency.

Additionally, I have automated certain settings using the Actions feature in the Legion software while off AC:

  1. Power mode: Quiet.
  2. GPU Working Mode: Hybrid-Auto (switches to integrated GPU when on battery and both integrated and discrete GPU when AC adapter is connected).
  3. Display brightness: 40.
  4. Deactivate GPU: Kill apps.
  5. Keyboard backlight: Off.
  6. Refresh rate: 60 Hz.

I have also enabled advanced power options using the provided script, which unlocked hidden settings and options.Now, I would like to know which of the many extra settings that have appeared can be changed to further maximize battery life. For example, I have already changed AHCI Link Power Management to Lowest and Energy Saver policy to Aggressive.[Script used to enable advanced power options]

powershellCopyif (!$IsLinux -and !$IsMacOS) {
    # Unlock Power Plans by disabling "Connected Standby"
    Set-ItemProperty -Path 'HKLM:\SYSTEM\CurrentControlSet\Control\Power' -Name 'CSEnabled' -Value 0 -Force

    # Unlock hidden options
    $PowerSettings = Get-ChildItem -Path 'HKLM:\SYSTEM\CurrentControlSet\Control\Power\PowerSettings' -Recurse -Depth 1 | Where-Object { $_.PSChildName -NotLike 'DefaultPowerSchemeValues' -and $_.PSChildName -NotLike '0' -and $_.PSChildName -NotLike '1' }
    ForEach ($item in $PowerSettings) { $path = $item -replace "HKEY_LOCAL_MACHINE","HKLM:"; Set-ItemProperty -Path $path -Name 'Attributes' -Value 2 -Force }
}

    I can't determine the advanced power options available on your laptop just by looking at the images. The advanced power options available on your laptop may vary depending on the model and manufacturer.

    -

    Here are some of the common advanced power options:

    1. Processor power management:

    This option controls how the processor speed is managed. You can choose to have the processor speed be automatically adjusted based on the workload, or you can set a fixed processor speed.

    -

    1. Hard disk sleep:

    This option controls when the hard disk turns off to save power. You can choose to have the hard disk turn off after a certain period of inactivity, or you can disable hard disk sleep altogether.

    -

    1. Wireless adapter power management:

    This option controls when the wireless adapter turns off to save power. You can choose to have the wireless adapter turn off after a certain period of inactivity, or you can disable wireless adapter power management altogether.

    -

    1. USB selective suspend:

    This option controls when USB devices turn off to save power. You can choose to have USB devices turn off after a certain period of inactivity, or you can disable USB selective suspend altogether.

    -

    1. Display Power Management:

    This option allows you to control how your laptop's display behaves to save power. You can set the display to turn off after a certain period of inactivity or adjust its brightness settings to conserve energy.

    -

    1. Sleep Settings:

    This option determines how quickly your laptop goes into sleep mode after a period of inactivity. It works in conjunction with other power-saving settings to help reduce energy consumption.

    -

    Remember, the extent of available options can vary significantly between different laptop models and manufacturers, so it's alright if you can't cover every single possibility.

    Sorry, that's a bit too vague. Could your be more specific with the advanced power options available on my laptop?

    Hello Aadil, how are you doing?

    Welcome to the Microsoft community!

    I'm glad to be able to assist you at this time.

    --

    Based on what you've already done to improve the battery life of your Lenovo Legion Slim 5 Gen 8, here are some additional tips that might help you get more battery life:

    1.USB Selective Suspend:

    This setting allows Windows to turn off USB devices when they are not in use, which can save power. You can find this setting under the advanced power settings.

    -

    2.Wireless Adapter Settings:

    In the advanced power settings, you can also configure the power saving mode for your wireless adapter. Setting it to a lower power mode while on battery can help conserve energy.

    -

    3.Hard Disk Power Management:

    Configure the power management settings for your hard drive to make it enter low-power mode more quickly when not in use. This can be found in the advanced power settings as well.

    -

    4.Processor Power Management:

    Under advanced power settings, explore the options for processor power management. You might find settings related to minimum and maximum processor state. Adjusting these values can impact power consumption.

    -

    5.Display Timeout:

    Consider reducing the time it takes for your display to turn off when not in use. A shorter timeout can contribute to power savings.

    -

    6.System Cooling Policy:

    You can modify the cooling policy of your laptop. Choosing a passive cooling policy can reduce the need for active cooling, which can save battery.

    -

    7.Background Apps:

    Review the list of apps running in the background and disable those that you don't need. Background apps can consume resources, including battery power.

    -

    1. Windows Update Settings:

    Configure Windows Update to run during specific times or manually. Updates can sometimes run in the background and use up battery power.

    -

    Remember that the impact of these settings on battery life can vary based on your usage patterns and needs. It's a good idea to test each change and monitor its effect on battery life.
