Lumia 950 battery drains rapidly

My Lumia 950 was at 95% battery today.  I had it in my pocket for 2 hours and didn't take it out once or use it in any ways.  After 2 hours I pulled my phone out and it was at 72% and it felt very hot.  Is this the experience others are having with their Lumia 950 or does this sound like I may have a defective phone and/or battery?

    SOMETHING is going on in the background.  In an effort to analyze this from a pure data perspective I've been keeping my eyes on different metrics - data usage, battery, etc - and over the course of 3 hours 'System' has used 200MB and I've done nothing but try and figure out what the problem is with this phone.

    I just looked at the Data Usage screen and I see that ATT has been replaced with 'Maritim' and it's increasing but I haven't leave my home office/wifi. 

    Also, it's worth saying that since all of this started happening Windows Hello stopped working.

    I did a hard-reset to get the update, and that worked.  Note, the phone will show the reset stuck at 0% even though it's not really, for quite some time.  I had no issue with the reset other than that mostly cosmetic issue.  (Putting aside the fact I had to hard-reset to get the update....)

    After the reset, my battery improved noticeably, but is still no where near my HTC One M8.  As others have noted, something is going on in the background.  Edge clearly shows the highest battery usage, even though it shouldn't (it's 35%, and the next is 15%).  I notice that syncing with onedrive is inconsistent, and that might be part of the issue.

    Just a thought, but I've noticed that Chrome on the pc eats my pc (SP3) battery, and really eats cpu cycles.  I wonder if, since Edge is now a Webkit browser (right), if that is a Webkit issue?

    Clearly, Msft needs to fix this.  Stuff is going on in the background that doesn't need to be, and that is killing battery life.  Hopefully they get this fixed.

    I went through the pain of the factory reset and then received the update.  Will see if that helps the battery drain.

    Update after the full factory reset, second day. Today more intensive use from 6.30 till 21.45 battery 20% left.

    Used navigation plm 1.5 hrs, call plm 4 hrs most with bluetooth device connected, wifi and bluetooth on, nfc not in use. most battery use by display 71%, system 24% mobile data 3% wifi 1%.

    This is for me acceptable. no warm battery or else.
