This has been my solution as well unfortunately. I come from a time where you were supposed to always shut down the computer after your down with it, so it’s not a deal breaker. But it was convenient to use the sleep feature when it worked correctly on MacBooks without sucking the life out of the battery.
I'm not a fan of videos. I like clear concise directions. I've been trying to find them in this thread and must have missed them.
I have a rMBP mid 2015 running Mohave. I take it off the charger at 100% and by the next evening around 6PM EST its 47%. Battery health is good.

I used the: 'sudo pmset -b tcpkeepalive 0' method. Shuts off Find My Mac, which I'm not happy about, but I can live with. In 'pmset -g log' I do not see any logging between the time I close the lid and the next time I open it. To me that means the power usage is minimal. Before I saw tons of logging related to mDNS Responder, Cloud Photos dark wake sync, etc.
Battery usage has improved with this method. I lost 4% battery overnight last night. 2% over eight hours today.
BTW, isn't it odd that the Cloud Photos Dark Wake Sync would exist when you have Enable Power Nap unchecked?

I had the problem weeks ago and it went away..Now it's crept back with a fury. I'm losing 2-3% per hour of sleep.
Been having stability issues waking up from sleep and restarting on battery power lately, so I did a summy fresh install of Sierra on an external HD using the Recovery OS, so my computer would update the smc/efi whatever the devil it updates during a fresh OS installation. Then I did a PRAM/NVRAM reset, enabled rootless mode to give Onyx access to my system folder and done the entire run of cleaning up system stuff, rebuilding caches, repairing permissions etc, and gave safe mode a run and restarted, and then disabled rootless mode.
My machine has since become stable as a rock, and I wanted to give exclusive hibernation mode (using sudo pmset -a hibernatemode 25 which didn't work for me in the past) a try while completely disabling standby mode. It works like it should this time around, and I'm now a happy camper.
Settings below
pmset -g
System-wide power settings:
Currently in use:
standbydelay 15
standby 0
womp 0
halfdim 1
hibernatefile /var/vm/sleepimage
powernap 0
gpuswitch 2
networkoversleep 0
disksleep 10
sleep 180 (sleep prevented by coreaudiod)
autopoweroffdelay 2
hibernatemode 25
autopoweroff 1
ttyskeepawake 0
displaysleep 180
acwake 0
lidwake 1
I'm almost tempted to test out standby mode once again to see how much battery power I lose when not resorting to hibernating before powering down, but nah. This is as a good as it gets.
I now have a brand-new battery, for which I have managed to put the kibosh on a ticking death senstence. It doesn't drain anymore, and I'm not risking going back to the mess I've finally dug my laptop out of.

I reviewed your entire thread, as I have similar problems with power loss on my Mac Pro.
I don't have enough data points to tell if this "really" worked, but it seemed to help. I uninstalled Malware Bytes and it seems to save about 4-5 percentage points each night. I've only tracked it a couple of nights, but wondering if that's one of the culprits.
Might be worth a look (?).
Check the pmset log - if there are any errors which prevent deep sleep. For example, like this:
$ pmset -g log | grep -i err | tail -1
2018-12-02 01:25:20 +0000 DarkWake DarkWake from Standby [CDN] due to /HibernateError: Using BATT (Charge:50%) 5 secs
After fixing it few months ago by resetting /var/vm/sleepimage (see my post here from Sep 15) I started seeing it again recently and the battery drain issue reappeared again as well. I should probably reset sleepimage again...
(MBP 13" Early 2015, High Sierra)

Love this reply because it is so obvious...and I'm guilty of it, too! I was wondering why my Mac was losing power while closed, and it really does make sense to turn it off, especially when you're not going to use it for awhile (although this is seldom).
But it doesn't solve the underlying problem. I suppose it's analogous to saying you want to take your car on a cross-country trip, but you need to stop every four hours to keep it from overheating. That works, but it doesn't solve the problem.
Apple should solve this.
I had this issue but someone here helped me solve it using pmset. If you open terminal and while the charger is disconnected (ie. running only on battery) run pmset -g what does it show?
I think this is what you're asking me to show (let me know). Thanks.

The standbydelayhigh is set for 24 hours. I would do:
sudo pmset -b standbydelay 3600
and see if that makes a difference. That's one hour. Change it how you see fit of course.
IIRC I had to do both stanbydelayhigh and standbydelaylow. The difference, I believe, is standbydelaythreshold; yours says 50 = 50%. So you can say above 50%, hibernate in 3 hours and below 50% hibernate in 1 hour. Or whatever.
Anyway, give that a go, it make a huge difference for me.
I've been experiencing this problem since upgrading to High Sierra and then Mojave (10.14.3). (Sierra does not have this problem.) I have had a case open with Apple Care for months trying to resolve this. I was just told by Apple support that engineering is now looking at this as a real issue. Whether anything gets resolved is to be seen.
Remember when apple made great software and products?! I miss those days...
Apple used to advertise that macbooks could sleep for 30 days. Remember that? And it worked until 2016 maybe? Not sure on the exact date, but at some point before then, the macbooks reliably consumed very little power while closed and then after that they just chew through battery.
Remember, the used to ADVERTISE 30 DAYS OF SLEEPING. I assume they don't anymore but I haven't checked the website in a while.
EDIT: They do still in the tech specs claim
Apple BRING QUALITY BACK! I'm done with Apple products until they do.

- Up to 30 days of standby time

I still have the original iPad I bought when it was released. I stopped using it in 2012, but last year I charged and used it to test streaming videos over local network, left it to sleep and forgot about it.
Fast forward 9 months, I clicked the power/wakeup button (it was sleeping, not turned off) and lo and behold, it still had 40% of battery power left. Streaming videos and light browsing yields 5-7 days of use on a single charge, on a battery that's 8 years old.
Apple's Products specs have gotten better over the years, but sadly quality has not.
