I have the i5/dgpu model and had 5-7 hours of battery life prior to trying to reinstall the driver from the driver pack from Microsoft. Unfortunately I cannot post the link here (due to lack of posts), but a simple google search can lead you to a thread in reddit that will show you how to do it.

I still need to verify this for a couple of days, but I think I can get up to 9-10 hours now without having to do a factory reset.

I can confirm that I am getting about 9 hours of battery life for light browsing/working. However, I did do the following after:
(1) Uninstalled the Intel Display Driver listed in the Programs & Features
(2) Installed the Driver again via Windows Update
(3) Uninstalled the nvidia driver
(4) Installed again using the windows driver package

I don't think you need to do the exact same thing. The main points are to uninstall all of the display drivers and then do a reinstall.

i7/16/512/dgpu, I have been able to get 10 hours on occasion, but usually average between 8-9 hours on most days. Using battery saver and brightness between 50-65%.

Well I plan on doing it this weekend because my Book battery life has gone to crap. I really don't know what happened. I used to be really happy with it. I could walk around work all day with the screen detached and still have decent battery left at the end of the day. Even at brightness at 25%, the tablet will be near death by lunch. I wish I knew what I did to screw it up.

Did you find a fix? I'm convinced it's a glitch of some sort because although I get 4-5 hours usually, occasionally I'll get 7-8. I think the most I ever got was 9, but I have never come close to the 12 hours promised.

Battery life went back to normal after doing a full reset. But I didn't reinstall everything that I had before. I'm running what I need and only that. For me it was worth the time. I'm not noticing any crazy drain issues like before.

I did get a copy of BatteryBar Pro. I love having that because it shows the actual mW being consumed and shows it in the system icon tray so I am very much aware of what is happening at all times.

*edit*
One thing that still happens is sometimes my Surface Book will consume a lot of power when I have no wifi connection at work. If I then hook it up to my hotspot from my phone, it will calm down pretty quickly. Every single time, hooking it up to the internet fixed the CPU from running constant 50%+. I tried stuff like resetting and that did nothing to help. Very weird. I wonder how much MS tests these things with no wifi available.

I don't consider it crazy because I can recognize it and fix it.

this could be caused by some app misbehaving when it has no internet connection. There's a good chance you can see which app is doing it by looking in Task Manager....

I'll be sure to write down what's throttling the CPU next time it happens but it is not a specific app. It's some kind of background task/service thing that maybe apps would call. And I have no idea how to trace it back to an offending app or the OS even.
