Your reports show Connected Standby is functioning so, it really isn't shutting down completely. I don't recommend this personally, but you DO need a reg edit to completely disable -

Unticking the fast startup alone isn't going to change much.
I don't personally se 10% drain over 24 hours as excessive, but obviously you do.. I'd create a restore point manually (you may need to turn on System Restore if it isn't on now) and then try making the registry change (but again, this is not recommended).
I'm old school, and Connected Standby was a huge change for me and took me quite a while to "embrace" since I'd always had computers where "OFF meant OFF".
Hope this helps (even if it isn't tied up in a bow nicely). Please DO mark as Answer if it was of assistance.
