Any word on battery life?

They added features, so even though the battery probably has more capacity, or the CPU is more efficient, I expect the extra power those features demand will offset any improvements in that area.

This is the only reason why I haven't bought one. I don't want yet another device I have to charge daily or every other day.

Give me an iWatch with a battery that lasts a week or longer and I'm sold.

It really isn't a problem unless you are someone who sleeps with their watch on.

Exactly the same: 18 hrs on both.

Nothing official, but my guess is that it's relatively unchanged: charge it every night.

a watch that needs a battery? yawn.

E: I expected downvotes, but I'm actually kind of serious. It shouldn't be impossible to get a small but interesting amount of tech incorporated into an automatic watch.

I didn't down vote you but this comment is like someone complaining that their iPhone only gets 36 hours battery life when their Nokia 3210 got them through a couple of weeks. I'm not sure if you've used an Apple Watch but battery life just isn't a concern at all. You take it off at night, put it on the magnetic charger next to your bed and put it back on in the morning. Unless you want sleep tracking there's no need to wear it at night and the battery easily gets through an entire day with 20-30% charge left. In other words there's a reason they didn't seem to even mention battery in this keynote - people have found it's not really an issue. Of course there are extreme use cases where it is (what if I go camping for a few days) but these hold true for an electronic device.

It really is an issue for me when it comes to anything fitness-related. Recording exercises drains it fast, and I am willing to bet that the GPS is the same story as heart rate -- it will probably sample every 5 minutes or so when you're not exercising and then bump up the frequency when you are. Which means it still can't be used to capture anything over a couple hours.

I hear you, and I can see how some people will enjoy owning Apple or Android watches.

But I'd still be more interested in news of a self winding watch that could somehow also deliver 30mA at 3.3V every 5-10 minutes to power a GPS module and a bit of NVRAM, even if it's in the $3-8K price range.

well my wind-up watch is rusty these days

Well, automatics are great!

Solar powered Casio watches are great. They still have a battery though.
