Windows 10: Various Sleep / ModernStandby Issues, Related to Battery Drain

Sleep and Modern Standby Issue, common to Windows 10 laptops by Lenovo / HP / Dell / Microsoft; also directly relating to a massive battery drain.

See the diagram below for a diagrammatic explanation of the problem. I'm at the end of my wits. Lenovo are useless for troubleshooting. By some miracle, I already had them replace the laptop; the previous one was doing the same thing (although the inclusion of a Thunderbolt 3 dock is a new factor, the same symptoms are observed periodically without the dock involved...) Please can anyone help?

Windows 10 version 1909 (OS Build 18363.959)

Battery drains while on sleep mode.


even mine has a slow battery drain, using Win 8.1. Even when powered off, not in sleep or hibernate, but off. It still uses the battery to keep the clock going.
Turn off fast start, as suggested, hibernate over sleep as it uses less power, and if you aren't going to use it for several hours, shut it off.

 

Battery drains during Sleep/Shutdown

Hi Rahul,

If you are experiencing battery drains during Sleep or Shutdown, we need to check your battery settings and perform a battery saving. There are two related categories that we need to visit. These are the Power & sleep. Follow the steps below:

• Open the Action Center and click System.
• Select Power & sleep.
• Choose your desired time for Screen and Sleep.
• Under Related settings, click Additional power settings.
• We will be prompted to Power Options' control panel.
• Select Change when the computer sleeps.
• We need to customize our power plan, choose between Balanced (recommended) or
  Power Saver.

Let's proceed with battery saving, battery saver feature is the same kind of tools that can be found in mobile phones and tablets. It is off by default and won't turn on if your device is charging. These are the steps:

• Go to the Action Center and choose System.
• Click Battery saver.
• Select Battery saver settings. (Note: Battery saver is set to turn on at 20%, but you can set that higher or lower.)
  
• Adjust the Battery saver to your desired percentage.

Using these two processes will definitely improve your battery's life.

Let us know if you have other concerns.

 

Battery drains while on sleep mode.


Sleep Mode has never been efficient. In all my years of using laptops, I've always just turned them off and on. Battery drain is normal for sleep mode. Some people have had issues with the laptops not powering off completely and draining the battery, but if that's your issue, there is an easy fix. You turn off Fast Startup and check a setting in Device Management under Intel Management Engine.
