I like the compass! It's nerdy, but I like to carry one when navigating an unknown city, and I find it very helpful.

does anyone know how this tech works - this might be worth buying for hiking if it will work in the middle of nowhere

No sleep tracking, no SpO2 sensor. They must be working on this, it would perfectly well into their health theme, and they bought Beddit. Another year.

It doesn't have enough battery life to last through the night if you've worn it all day. They probably intentionally don't have sleep tracking to avoid emphasizing that.

Have people worked out how much various tasks and usage patterns affect battery life?

With a Series 4, I can get through the night. I suspect that a large part of that is that I keep "Wake Screen on Wrist Raise" off most of the time. Generally I only enable it when doing a workout (~30 minutes a day) and sometimes in the kitchen when using timers. Another factor is probably that I don't use it for much more than telling time, checking my activity level, checking weather, and reading the occasional text message.

If I charge to 99% or 100% during breakfast, I'm almost always above 60% at bedtime, and overnight with the Sleep++ app tracking uses under 20%.

> all-day 18-hour battery life. Is there a standard for what "all-day" means? I think most would initially assume 24 hours, but thinking about it more, it seems reasonable to consider "can work from wake up to sleep" or "can work from sunup to sundown"/

1980 watches: battery lasts a couple of months 2019 watches: battery lasts a couple of hours

You forgot to mention that in 2019 you are wearing on your wrist what in 1980 would be considered a super computer and occupying several shelves worth of space.

Edit: Some info that I found online. According to this article from 2015 [1 ]the apple watch is equivalent to two iPhone4s (Not sure I believe that but if true incredible). Also this quote:

"Meanwhile, the Cray-2 supercomputer from 1985, which is the fastest machine in the world for its time, is now only equal to an iPhone 4."

Another quote :

"The Apple Watch performs about 7 billion FLOPS"

According to wikipedia [2]:

"The Cray-2 released in 1985 was a 4 processor liquid cooled computer totally immersed in a tank of Fluorinert, which bubbled as it operated.[8] It could perform to 1.9 gigaflops and was the world's second fastest supercomputer after M-13"

So assuming that all of the information is correct then it is indeed true that the Apple watch from today is many times more powerful than a super computer from the 1980s.

I think all day depends on the specific device. For example, I would accept a 10 hr battery life for a laptop or wireless headphones as "all-day" because that will cover a full work day and people aren't expected to use those devices 24/7. 18 hours for "all-day" on a wearable seems reasonable if the expectation is that it will be used only when the user is awake. A complicating factor is that Watch OS 6 is supposed t…

I quite like the idea of a smart watch, but having to charge it every day is much less appealing.

I agree with this sentiment. But then I discovered the Fitbit has a 7 day battery life. That's a game changer.

Can you make a call from your Fitbit?

Considering how fast Apple Watch charges, a 7 day battery life isn’t that compelling considering how much you get from an Apple Watch compared to Fitbit.

Only reason I don’t have an Apple Watch is because you can’t stream Spotify over cellular, you need to have your phone with you. What’s the point? I want to go for a run and stream music with just the watch to my Bluetooth headphones. I don’t need the watch if I have to bring my phone with me.

You can stream Apple Music over WiFi/cellular without the phone. Not sure if that will include Spotify at some point but I do know the new watchOS has opened up a lot of those APIs.

Apple Music is a disaster when it comes to music discovery, and frankly their app is very much behind compared to Spotify. Even on iOS it feels like a web app, something I didn’t think I’d ever say about Apple’s own, built-in app.

"Wake to Sleep" seems to be the generally accepted definition, i.e. you won't have to charge it during the day during normal usage. How long you're awake for can vary though, I've seen anything from 8 hours to 20 hours of battery life be referred to as "all day".

Accepted by whom? I hate it when marketers get to make up their own meaning of commonly used words, usually making them mean less than they ordinarily do. With "all-day" meaning anything between 6.5 (see parallel comment) and 20 hours, it's becoming a worthless and purposefully confusing term. (Note if that a physical store advertises it's open "all day", you expect it to be open from 00:00 to 23:59.)

Well in this case you don't have to wonder what it means because they say exactly how long—18-hours.

Also, nobody says "open all day" in retail because retailers would be more explicit about the fact that they are open at night, thus you have 24 hour convenience stores, not "all day".

My Apple Watch ( Series 1 ) is still alive and working quite well. It lasts for 8-9 hours if I don't use the heart rate monitor, while doing sports. I think at this point I could say that my Apple Watch is not "all-day" battery life.

Wow, I feel lucky now! My watch (Series 0) will last about 16 hours, 15 hours if I do a heart tracking working.

It's been worn every day (and charged every night) since it was purchased.

Every sane person would assume that but because they were unable to meet the "all-day" target, they kept it as a marketing phrase and added the actual life time.
