Surface Book Battery Life - what are you getting

I'm getting great battery life just enabling hibernation and disabling sleep. I don't know why people are afraid to do that. Booting up from hibernation takes just as much time for me to wake from sleep, and I have Windows hello enabled, too. Getting 7-8 hrs daily use.

Well, there isn't exactly fear involved. ;-)  I was just somewhat reluctant to incur the extra SSD activity, but heck, today's SSD's are designed to last a lot longer than I will probably have my SB.  I'm sure I'll have to have the next version of the Surface Book.

So, I have turned off sleep and turned on hibernate.  Yes, it works just fine.  I do have to touch the power button though, unlike sleep where all you need to do is open the book, and BAM, you are exactly where you were when you closed the lid.  I still look forward to getting this fixed.

Had the exact same thing happen to me.

Same thing here, sometimes not even 3 hours. Same exact model as yours. Unacceptable.

I am also wondering how all the professional reviewers get 10-1 hours and the normal user gets 5-7.....

Probably because the early reviewed units didn't have Windows Hello and a few other features available (which drown battery life.)

I've found that I get good battery life as long as I don't close the lid and invoke sleep.  As soon as sleep occurs, my Book battery goes to **** in a hand basket.

I'm patiently waiting for the January fix.  I have Microsoft Complete and I know the people well at my Microsoft Store having bought a number of computers there since they opened.  I'm very confident in my Atlanta Microsoft Store support.  I'm also very confident that this will be fixed.  As for now, I'm just shutting down before I close the lid.  Booting up my SSD is fast, so it's just a minor inconvenience for the next few weeks.  I don't want to give this computer up as cosmetically it is perfect and software-wise everything runs perfectly except for sleep.
