After a week I've disabled most background activities, turned off Hello, turned off Glance, page prediction and anything else. I now feel like I'm sacrificing, yet still it burns through the battery. From 100% to 78% in an hour of pretty much just reading news and email, always slightly warm. My wife smirks nearby with her iPhone, which barely drops 5% while she does the same stuff. This is not ok. I'm going to exchange the phone in hopes that this was a defective unit. If not then I'll go to any of my older phones, all with better batteries.
