>sometimes you get a doofus manufacturer with lousy drivers, so 1 in 20 times you pull your laptop out of your bag and it's red hot with a drained battery.

That's due to "connected standby"[1], which is to have laptops behave more like a phone when in sleep. This is in contrast to S3 sleep, which basically halts all activity. Sounds all good in theory, but as soon as you allow code to be run while in sleep, it's easy for some runaway app (OS or third party) to eat through your battery even while your laptop is "sleeping". Worse is that there's no way to force sleep, so your only choice is hibernate, which is even worse than S3 sleep before.

“Modern standby” is indeed the culprit in many cases, maybe even the primary one these days, but to my understanding it can still be a crapshoot on laptops that support S3 sleep since it’s up to the OS to detect that the lid has been closed and put the machine to sleep. This has been a problem for a very long time, since well before it became cool to pretend to be a smartphone and not actually sleep the machine.

There’s also wake on LAN which if enabled can rouse the machine from sleep after it’s successfully entered a sleep state.

That feature also works just fine on macs, though.

		Macs have a completely different operating system managing what happens when the laptop is doing its standby stuff, though.

		It works fine, except for when it doesn't. Source: My macbook has drained its battery flat while closed in my bag dozens of times. Then it just stopped doing that on an OS update. I still have no idea why.

		On mac it works slightly more reliably than windows. I've had both devices drain in standby.
