Battery drainage on XPS 13 9360
I fully charged my two days old XPS 13 9360 to 100% two days ago. I have not used it since this morning (one day later), and i noticed the battery has dropped to 86% over the two days while the laptop was completely powered off (unplugged). is this normal?

If you do not know if your system does modern standby, run the command below and copy and paste the top part of the result.
powercfg /a

Thanks your info,
powercfg /a
The following sleep states are available on this system:

The system firmware does not support this standby state.
This standby state is disabled when S0 low power idle is supported.

Yep, it is a modern standby system. My system used to burn 1-2% per hour when in modern standby, when the display was off. One way to stop that is to put into hibernation after some period of time, say 60 minutes.
The system was designed to behave as a phone. If it is in modern standby, you can tap the space bar and it will pop back up. While the display is off, a small part of the system remains active and can do certain tasks. Certain types of Apps, like Groove Music, will continue to function, perhaps even with the lid closed. But desktop apps like iTunes, will suspend.
So, decide how you like to use you system and put the options in a configuration best for you. There are places which describe modern standby, but it has been evolving so watch the date of your info.

Yes—by default, the XPS's Sleep mode is actually something called Modern Standby (also known as Connected Standby).
See, Microsoft has decided our PCs should be more like smartphones. They want to be able to install updates and keep their Metro apps "refreshed" (current) even when we think we've suspended them.
So even though you think you're putting your XPS into Sleep—and it still says "Sleep", BTW—you're actually just turning off your display, pretty much. Your network connection stays on, as do most of your devices. That's why your battery's lasting only a day, rather than several days to a week, as you'd expect.
I found out about this because my USB mouse, keyboard and cooling pad were staying on when I thought I'd put my XPS in Sleep mode. I called Dell, but the agent had no idea what was making it do that. He suggested I use Hibernation instead. But it takes my XPS at least 30 seconds to resume from Hibernation. Sleep would resume nearly instantly.
A few days later he emailed me and said it was "normal behavior" now to leave the system on in Sleep mode, but he couldn't explain why. He also couldn't explain why I (or anyone) would want to leave my portable PC running when I wasn't using it.
The good news is, you can turn off Modern Standby. Just follow the directions in this IT Pro Today article:
www.itprotoday.com/management-mobility/disabling-windows-connected-standby
Once you've made that registry edit, reboot your system and normal Sleep should be back. You'll also get back several of the usual settings in Power Options (e.g. USB Selective Suspend) that MS hid because they would've interfered with your always-running system. Wacky, huh?
Cheers, A.

Unfortunately, this tweak does not work on latest Windows 10 2004

Is the system in sleep mode? Below are some troubleshooting links to resolve the issue. I would also leave the laptop plugged in when off as well.

Adrian G001> Is the system in sleep mode? Below are some troubleshooting links to resolve the issue...
It doesn't seem like you've actually read this thread. Yes, the PC's in Sleep mode—that's exactly the problem. Microsoft has changed the way Sleep mode operates. Rather than just using a trickle of power to preserve the current session in RAM (the traditional behaviour), this new, so-caled "Modern Standby" leaves most of the PC's components on, draining the battery. It's because Microsoft decided our PCs should be more like smartphones, recovering from standby instantly (and, in some cases, even remaining online).
They didn't give us a choice, either. If a system's new enough to "support" Modern Standby, it's now been automatically implemented in a recent Windows update.
And what a drag! When we don't want to leave our laptops running for short periods, we can no longer just close their lids and use Standby (AKA Sleep) mode, because:
• We risk overheating (you shouldn't leave laptop components powered up with the lid closed); and/or
• Draining the battery (e.g. if using it in transit).
We must now always use Hibernation mode—saving the entire session to disk every time, and adding a considerable wait to recovery time. It's a huge step backwards in portable computing.

Gee, really—plugging your computer into AC keeps its battery from running down? I had no idea! Obviously, that solves the entire problem. (LOL) Unfortunately, it doesn't prevent it from overheating.
The wackiest thing is, most Windows 10 users don't even know this change was made. I found out only because my USB peripherals were suddenly staying on when I closed my laptop's lid. (Did I mention that?)
It's a ridiculous, sneaky, wasteful, inconvenient, unnecessary change masquerading as some kind of improvement—and I don't know why Dell went along with it. They didn't do their customers any kind of service.

You need to use the dword PlatformAoAcOverride set to 0
The CsEnabled does nothing as far as I could see

You're absolutely right! The "CsEnabled" registry hack stopped working a couple of Windows 10 versions ago—but I'm amazed and pleased to find that the PlatformAoAcOverride trick does indeed work! (I just tried it with Windows 10 version 21H1.)
It's great having regular "S3" Standby mode back—I no longer have to use Hibernation every time I step away from my PC. Sure appreciate it!
For anyone else who'd like to do this, the process is described here:
borncity.com/win/2020/11/26/windows-10-v2004-cant-deactivate-modern-standby/
...and here are the actual steps:
1. Run Regedit as an Administrator (Start menu > type "regedit" > in the results that appear, right-click "regedit", then click "Run as Administrator")
2. In Regedit, go to this registry key: HK Local Machine\System\CurrentControlSet\Control\Power
3. Right-click in the right side of the window, point to "New"; then in the pop-up menu, click "DWORD 32-bit value".
4. A new entry appears in the window. Name it PlatformAoAcOverride (those are all letter O's, not zeros) and leave its value (at the right) at "0".
5. Reboot your system. Normal Standby mode should now be available. To confirm, open a command prompt window (Start Menu > type cmd and press Enter), then enter the command powercfg /a and press Enter. "Standby (S3)" (regular Sleep mode) should now be available, while "Standby (S0 Low Power Idle)" (the so-called "Modern Standby") should now be unavailable.
