surface book battery drain while shut down

Also, just booted up my Surface Book having not used it for about a week to two weeks and the battery drained from around 80% to 25%. That is a bit disconcerting. I don't have any other piece of technology that does that while completely shutdown.

Yeah same things happen to you I have it! I mean it's seems they won't help his on this! They extend the pried of fixing to January just to ignore us! I won't take anything from them ! They have no respect for is ! I paid $1800 for nothing !

For what it's worth, I'm not surprised that they aren't giving us progress reports.  They can't know how long it will take to fix a bug, so they'd be reluctant to do anything that could be taken as a promise to fix it by a certain date.  But I am frustrated that they didn't just wait a few months to release the machine.  It's a great machine, but it clearly wasn't ready for release when they shipped it.

This happens to me too.  I always do a shut down when done using the device because of all I have heard about the sleep problems.  I left it shut down in the basement after using about 40% total power and when I went down to get it about a day, day and half later the batteries were at 0%.

I just want to add I have the i5/8GB/Dgpu.  This unit is about a week old, and is a replacement of my last unit.

I have done all updates, I have not touched any power settings.

My normal routine is to use it at night, I've used it every night since I bought it, and then in the morning put it on the charger.  I have not turned on in the AM to take note of any % drop, but I may now.

Of more interest is that I had to replace my last one due to main battery at 0% and not charging.  I think I may have left it off charge for a few days at that time too, but didn't think anything of it.  

Both batteries were at 0% this time but after a 2 hours or so last night were almost fully charged.

I will pay more attention to shut down at night levels and morning levels.  I'll post my results.  

If detaching works better I will try that as over the weekends it's highly likely I don't get it on a charger all the time.  I don't want to fear discharging a battery.

I hope the Jan patches fix this.

I'm very much looking forward to what the January update will do for battery life and in particular "sleep"..  I too power-down at night and definitely power down before putting mine in my commuter bag.  I've not experienced much more than normal battery drain of just a few percent while turned off.  

I will admit though that I'm a very heavy user and this is my main computer.  It powers up in the morning as soon as I'm awake and it powers down just before I go to bed, seven days a week.  It will really be nice to have "sleep" work like it should and not to have to remember to always power-down.
