I was charging my iPhone 6 at the end of each day or there about...with my watch on my wrist now, it's giving me 1.5 to 2 days of battery on my phone! I am not using it as much and can do quite a few things on my watch so for me this is a huge plus...

Can someone explain how the Watch works when it comes to receiving texts and emails even when you leave your phone home? I was at my GF's and left my phone at my house, still could receive texts/emails!!!!
1) Are the texts only iMessages? or all texts?
2) Does this work on any wi-fi network or only those that my Phone has accessed before?
3) Does my phone (when at home) have to be on?
Very cool feature I didn't know existed, I can leave my phone at home now and still be connected.
The battery drain is likely a result of people who got their watch on Friday spending so much time playing with their new toy.
Once people start to calm down and start using them in a more normal way, I expect the reported battery problems to go away.

I had been using a Pebble for about two years before the Apple Watch and never noticed a significant impact on the battery. Yesterday was my first full normal day wearing the apple watch, and I still had 75% on my 6+ at 4:30PM. This is a huge improvement! Maybe the Pebble was draining more than I thought.
I believe it works like that, I have yet to test myself until I get my watch. But I've heard that the watch imports known Wi-Fi networks from the phone. You can't add any yourself, but it gets them from your phone.
If that's the case, you are correct, and in certain respects you can forget your phone if you know you're going to be in a location that will have Wi-Fi you have been connected to. But in between those two areas, your watch won't really work.
This should have a positive influence on Apple's stock price once people that have purchased an iWatch find that they need to upgrade from their current iPhone 5/5s/6 to an iPhone 6+ for the increased battery life. Pure genius 
Well, until it ships to the user, the watch drains the battery by the user constantly checking their phone to see if it has shipped.

Turn on the exercise app, do an hour of jogging, watch the battery deplete by at least 20%. For me, this is the biggest drain. But still, I got around 17 hours of battery life yesterday (around 4 standby). Without exercising I'm sure it would hit 20 hours.
Not great, but not terrible. Still, I'd love one that lasts for a few days. I actually feel asleep with mine last night, and the low battery warning woke me up! lol

loliPhone 6 Plus & Dexcom G4 CGM
I have been using a Dexcom G4 CGM. This is my blood sugar monitor that connects to my body and through bluetooth to the Receiver and then bluetooth to my iPhone. I have seen more battery drain with the device connected. I expected this, just like I expect the Apple Watch to cause some type of drain. Even though they both are low-energy bluetooth devices.

Being an android user with a moto 360 i find my battery on my note 4 to be significantly increased. I'm sure Apple will fix any issues with a software update.
I was thinking the same. I believe this will even out for a good many people once they settle in to using the watch normally. I have to think that people are in "tinker with my new toy" mode. I know I was on launch day and I got worried about battery life. Yesterday? It was great. It's been great all day today, too.
While I understand your optimism, radio power doesn't become more efficient, just because the CPU does. In fact, most of the time the CPU is idle doing very little when background tasks like this are happening.
Know what would drain battery life significantly, using location services constantly.
True on the in-between but that really is a pretty cool feature and one I didn't know about. I can see a life with my phone glued to my hip more an more now. Just used Apple Pay on my watch at Whole Foods and had a crowd of 7 cashiers around me OOHING and AWWWWING. Was awesome!

Yup. As my iPhone had used that wi-fi before it then worked on my watch even though my phone was at my house 5 miles away. Super cool! Text/Email! No calls though...
Going going backwards and forward with Bluetooth LE for a device that'S this close is a negligible amount of usage of power.
If people are getting push notifications to their phones (when before they were polling), well that will obviously have an impact. The may also be using more GPS, fiddling with their watch more (its a brand new toy ;-). If the communication between the watch and the phone is WIFI instead of bluetooth, that would use more power (but it would also drain the watch faster). I always find funny how people are not really conscious of their own usage pattern, especially in a new device.
If someone was in the past checking notifications on their phone several times a day, and now they're not. There is no reason on earth why they should have a bigger Iphone battery usage.
If they were essentially not replying to those notifications all day long, well I can see how adding the watch would use more. Might as well turn off notifications then ;-).
These are probably the same people who insist the watch should be independent from the phone, when their communication pattern has already an impact on their much bigger phone.
Finally, sometimes confirmation bias also has an effect. You're looking for some change, some pattern and you spot it no matter if it is significant or not.
How can you say that with such certainty? Yes radio communications can be a power-hog, but the amount of data that is transmitted is limited to a minimum and Bluetooth LE is already "Low Energy".
This battery drain problem affecting some users may well be linked to some software bugs that will be fixed in updates and won't require new hardware.
Same thing with the "slow loading" of apps/glances. Considering the small amount of data that apps are allowed to send to the watch (couple of lines of text, layout data and small images) the fact that some take several seconds to load according to some reviews may again be the result of a buggy 1.0 release and may be fixed in updates.

There is no miracle battery that last a few day. To last two days with you current usage pattern, the phone would need to be 35-40% bigger at least. If the SOC/mem/screen power usage improves enough in 3 years, you may get that second day (or they make the watch thinner ;-).
If one lasted a few day, it likely would die in the middle of that other day, or while you fell asleep and forgot to charge it that other day. There is no escaping, you eventually have to charge it.
This is why you never buy a first gen Apple product. Let someone else be Apple's beta testing guinea pig. #S-Upgrade-Cycle-4-Life
Its the "new device syndrome". People don't seem to realize how much they fiddle with their new stuff all the time. Its a constant at all new device release.
I too am finding very little impact on my iPhone 6 Plus, but I haven't been using mail on the Apple Watch. I love using messages on the Apple Watch.
Really, most people being happy with their device, which is what seems to be the case, is the reason you don't by gen 1? Well, nice to see they're selling the reality distortion field in your neck of the wood.

No its not. It is bluetooth LE, and it is sending micro snipet of data. You can stream mp3 through BT LE from your phone for hours (and that's a hell of a lot more of a drain). Its the phone itself getting/transfering communication data through the Cell or Wifi network that's usually the drain. Especially if it is getting background push notifications (instead of a lot less frequent poll notifications).
Bluetooth affects battery more than not having bluetooth enabled? What kind of wicked sorcery is this?
