Surface Book Battery Life - what are you getting

If you want to add back options such as max processor state, cooling policy, you have to do so yourself, for example: http://www.eightforums.com/tutorials/51027-power-options-add-remove-min-max-processor-state.html

You can then create your own customized profile. CPU and display are the two main consumer.

But again I think you need give few days to allow the battery program to calibrate. Whatever it reports now is not accurate. Like someone else suggested, leave your laptop on and run down your battery overnight (turning off sleep) and then the number reported will be more realistic.

I got my surface book last night, had to do a factory reset to set it up because someone had user name and password already set on it.  had it charging all day at work and brought the tablet part only home, two hours of screen off time and ten minutes of use and it was dead from a 100% charge. Taking it back first chance I get, closest best buy is an hour away......  not a happy camper

With hibernation enabled instead of sleep, and screen at suggested brightness setting, I'm easily getting 7-8 hours of daily use.

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.
