Do you think the iPhone is going to have drastic battery drain being connected to a watch all day? I haven't heard any reviews on this.
Got a tip for us?

iPhone battery life with Apple watch

My iPhone 6 lasts me all day and then some, and that's connected to my Pebble smart watch (both normal and low energy Bluetooth connections) and periodically to my cars integrated Bluetooth when I drive.
I think the phone will last fine. It's the watch I'm concerned about!

The affect the Pebble had on my 6 Plus was negligible. I don't think the Apple Watch is going to be much different; it should be fine.
It will be different. Your iphone 6+ (like mine) will have a even longer battery life with the Apple watch because we can actually reply to notifications from the watch without waking up our phones like we have to with the Pebble.
I don't think it will be a drastic drain at all. In theory we will need to use the iPhone much less when paired with an apple watch, so hopefully that will make up for the extra battery that bluetooth requires.
If the Apple Watch noticeably lowers the battery on the 6 Plus—well then RIP iPhone 6, 5S and 5 owners, lol.
Seriously though, since it is new hardware, the software might need to work out some bugs. I could see it potentially getting "stuck" and causing increased battery drain, but probably rare. I've had that happen with brand new iPhones over the years. My iPhone 4 in particular would get stuck from time to time and I'd pull it out of my pocket and it would be really warm, almost hot. Rebooting would kill the loop and cool it down. But sometimes it would also drain quickly from continually looking for data connections when I was in an area of poor service. And I mean rather quickly—around 20% an hour in my pocket when it would get "stuck." Difficult to explain. Software updates seemed to fix it.
I've had a Pebble watch paired with my 6+ for over 3 months and the battery impact has been non existent.
Like others have said, I've had my iPhone 6 (and a 5 before that) paired to a Pebble for over a year. The effect on the battery is negligible. Whatever drain it causes is negated by the decreased use from not checking my phone every time I get a notification.
Screen on time is the biggest draining source or factor for the iPhone. So, the Apple Watch paired with Bluetooth LE will not be such an issue as the iPhone screen will be off. That is my opinion/reasoning.
Won't make any difference. I have my pebble steel connected to my iPhone 24/7 and it makes absolutely zero difference to how long the battery lasts (thanks to the beauty of Bluetooth LE)
If anything, it'll improve your phones battery, because you can turn off "display on lock screen" for every notification and stop them lighting up your screen 1000 times a day for 5 seconds at a time.

I use Bluetooth headset and yes the battery effected
Then you have a poor Bluetooth headset. I use both a Bluetooth headset and a Pebble and neither have had an significant or noticeable impact on my iPhone's battery.
Yes, Bluetooth 4.0 LE is VERY efficient. You probably won't even notice the extra drain.
It's the best in the market... I think
