Incredible battery drain during connected standby on a clovertrail windows 8 tablet

I'm experiencing infuriating battery drain during "connected standby" on a windows 8 tablet, Samsung Smart PC 500T. I bought it 2.5 months ago, the problem has been on for over a month, after some big OS updates from MS... I've tried to diagnose it any way I can, but this it it, thank you, not interested in this all connected standby thing, don't want to be a guinea pig anymore. I just want to disable it.

So - how to disable connected standby? Don't tell me "it's a part of windows experience" bla bla, the 'experience' is half baked so far...(to put it very diplomatically). I want to shut connected standby down, completely - and use good, old, normal windows 7-style sleep. Is there a service, registry key, anything i can do to disable connected standby?

On connected standby, I've got battery drain with airplane mode, no user apps open (anything that can be shutdown - shutted down), most metro apps deleted, just 4 left (metro IE10, Windows Store, Music, Photos, S-Camera), no nfc, no bluetooth, no usb accesories, no keyboard dock, all task scheduler stuff not only not allowed to wake the computer, but disabled at all, no auto syncing anything in widndows 8 (not syncing tiles, user account stuff, no push mail in outlook 2013), no auto updates to OS, anything (except for samsung own s-update service - it's fine, it's been long before and it didn't cause problems), no anytvirus, windows defender disabled..

Nothing interesting in the event viewer, with anything power-related filtered from the system logs..

I mean, man... What the ....?! How to find this something that drains my battery? I've been looking at cpu cycles (task manager and ProcessExplorer), and it's not conclusive, the most cycles is OS stuff.. some "hardware interrupts and DMCs", but not nearly enough to cause such drain...

I'm suspecting wifi drivers a little bit.. some weird logs I've seen in the even viewer.. But I'm going into connected standby <on airplane mode>. Wifi off. I even checked, I disabled the wifi driver in the device manager and still, battery drain on the connected standby

Yes, I'm all over updated. I'd even say updated too much from MS... This been working fine before.

Some powercfg -batteryreport (s) in the links below. Yup, played with powercfg /waketimers, device manager power and wake settings, powercfg /devicequery wake_armed (all turned off, nothing here from a loong time) and powercfg -requests. Clean.

On these pictures from powercfg -batteryreport, the columns are date/type of activity/lasted for how long/battery drain in %/battery drain in mWH. Suggesting you have a look at the last one. It's a record there... 18% battery drain in 4 hours. "Sleeping".

The tablet is lying on my desk, just sitting there, doing I've got no idea what, and 4 hours later boom, where all that battery juice went for?! I've got problem with the windows home button, it gets triggered in my bag accidentaly when I carry the tablet around, but it's a separate problem how to disable this windows home button. The connected standby battery drain is a different thing.

Much worse.

So:

QUESTION 1:

• how to disable this crappy connected standby thing that drains my battery and drives me nuts?

QUESTION 2:

• if it's not possible to disable directly, how to go around that? I don't need a button to do this. Telling what to do with windows registry is good enough.

QUESTION 3:

• if connected standby cannot be disabled in any way - how to diagnose which app/process uses cpu cycles, battery juice? I've been all over ProcessExplorer and Event Viewer, but maybe you know something I don't know...

And please spare me suggestions of clean boot, when I revert to "normal" state I'll have a ton of bloatware I don't need running with the OS.. there is a reason why a little bit tech-savvy people use such things as services.msc. De-bloating! Nope, I didn't touch the system services.. Yes I know it can cause a ton of problems, it's not this.

I don't need a clean boot, I need a way which device in the device manager uses so much power, what driver, what app, what service, what process, what thread, where it's located in the filesystem, at which times it's been active, how much cycles on the CPU it got since then...

And if MS doesn't already have such app in windows, there should be one, cause power issues on the clovertrail windows 8 tablets are ..... plague. For instance - this is exactly the problem (a review of similar win 8 tablet with the same connected standby issue) here - http://www.umpcportal.com/2013/02/connected-standby-battery-life-problem/

When even bloggers and tech reviews write about it, you know there's something in it.

But I guess stupid finger painting apps like freshpaint are more important as a selling point.
