Windows 10: Weird battery drain on sleep

My laptop seems to drain about 40-50% battery overnight on sleep some days.The sleep study reports of my laptop are attached below. The first image is of when the battery got drained and the second image is of the day when it didn't.I'm not able to figure out what is actually causing the issue.Pls look into the images and provide a fix to this issue.

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 drain in sleep and hibernation

Since a clean installation of Win 10 my laptop battery has begun to completely drain overnight when in sleep or hibernate modes. It is ok when powered off so I suspect the battery is ok.

Any suggestions?
