Can you check your event viewer to see if it woke at all during the 4 hours?

Do you gave an SD card installed? If so, see if the same thing happens if you remove it. A corrupt or bad card could cause that. Possibly even the internal storage which can be easily checks with the disk tools.

I checked , nothing there, and 3 hours stand by, I put SP3 to sleep this afternoon, cost 15% battery. Is this normal, or SP3 ' sleep is not a real sleep?

Something, a driver or store application it's preventing your tablet from going into hibernation if it is consistently happening at the four hour mark as that is the time the device modes from Connected Standby to hibernation or something is preventing it from actually entering Connected Standby.
From an elevated CMD PROMPT run powercfg sleep study copy the html file from the System 32 folder and open it in IE

I shut it down, and restart it then put it sleep for 1 hour, see what happens

All my system and drivers are updated, and I change wifi card to maximum performs according to the suggestion .

One of the issues with attempting the WiFi Work-arounds is that we don't know what the impact will be on battery life and Connected Standby. Rumor is that we should see a WiFi fix very soon from MS (maybe as soon as Tuesday which is the normal patch day).
