My SP4 gets very hot and drains the battery very fast even though it is asleep. I found it very hot in its sleeve and down to 28% earlier today. Found it dead later in the afternoon. This is one of MANY issues this device has.
(My SP4 is not part of the insider program)

Keep in mind that you are probably using hybrid sleep and don't know it. What I mean by that is that when you shutdown, you really don't. You'll want to disable Fast Startup if you truly want to shutdown completely, and you will then find that startup is slower....
Ah I had forgotten that. So "Hybrid Sleep" is really what I'm doing which is why the startup time is so short. I'll keep using that until Microsoft fixes the thing they mucked up with the latest update.
Has anyone heard anything recently from Microsoft? The last I read was that they were working it...sigh...

Open RegEdit and search for the key CsEnabled - you'll find it, Or
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power
Change the CsEnabled key from 1 to 0.
Disabling CS will remove the Sleep option all together, but you will find that you have more options available to you in your power profile configurations.
Can you provide the CS hack?
Why is a hack needed to disable connected standby? Sleep can be disabled (change the close lid option to do nothing and sleep time to never) and a hibernate time may also be set.
It's very common. And Panos, afaict, was lying through his teeth in the keynote.
With connected sleep enabled, I've never had my SP4 go below 5% per hour battery drain, and after the TH2 update it was closer to 11%.
I've disabled CS with a registry hack and changed my power settings to hibernate after 5-10 minutes (just in case I close the kbd or hit the power button accidentally, as I have - waiting 25-30 seconds to hibernate and then de-hibernate is kind of a pain if you just forgot one small thing).
Last night it went from sleep-hibernate and I turned it on this morning and had 97% battery still remaining.
Can you provide the CS hack?
I've set my power button to perform a shutdown while on battery. I've found the power up process is way faster than a hibernate. I don't leave open work when I stop using the SP4, so I don't need the advantages of hibernate versus shutdown and then a power up.
