Teardown of 38mm Apple Watch Sport Reveals 205 mAh Battery, Taptic Engine

Hmm, based on such a small battery it would appear Apple will not be able to have an always on display this first go around. That is kind of a bummer.

Maybe I'm missing something here but why would you want a display on when you are not looking at it?

Well, I'm sure we will all know soon enough, when we start seeing dozens/hundreds of people on these very forums saying how they got to the end of the day, taking off the watch as they slip into bed, and placing it on it's night charging stand with 40%-50% battery left.

Will also be interesting to see how this changes as more interesting to play with apps come along in the next few weeks/months.

Or they post a story that their watch was ripped off their wrist by an unsuspecting person.

Thieves now have a new high priority target and it's always exposed for the taking.
The next few months should be interesting...

On the flip side and a little off topic. I was thinking the other day on the subway that now (when a new iphone is in a case) that it's THAT much harder to tell the difference between an iPhone and another manufacturer's because they are larger. Before it was very easy to spot/pick out an iPhone. These days you have to look "harder."
 
So iFixit dinged the Watch because you can't make board level repairs to the S1 SiP. Seriously? Have they not figured out that miniaturization is here to stay and this stuff is only going to get smaller in the future?

Because if your arm is in a non standard position you would have to exaggerate the motion to get it to turn on (to see the time) versus it just being on with the time showing.

I guess the best example I have is laying down, until someone can test how sensitive the device is for turning the display on.

Very few people would have the ability to do more than replace the battery and/or screen (if possible)

How many average people would want or think they could tinker with the S1 chip?

The repair-ability for a device like this should be more about the band, the screen and battery.

What does that have to do with the display being on?:rolleyes:

Most of this is speculation for how hard it's going to be to get the display to turn on. I'd still want it off most of the time. No reason to waste battery of have people sneaking a peek at my last text;)

Hell, I wish my TV would shut off when someone leaves the room:D

Synthesizer's don't need to be charged every day and won't become obsolete once the manufacturer stops updating its firmware. Concert pianos last decades.

Your analogy is just as ridiculous as his, if not moreso.

We know you're excited about the Apple Watch, but let's stick to reality here.
Click to expand...

The person who answered your post was correct. It was you who compared a mechanical watch to a wrist worn computer.

You surmised that one is somehow superior because of battery life. Your analogy would be correct if the apple watch ONLY displayed time/date like a mechanical watch.

Now, I don't own and do not plan on buying an Apple Watchh. And as a musician I will tell you that synths do become obsolete. And if the manufacturer of your concert piano stops making parts for it.... Good luck maintaining it if something breaks.

Ummm, my 1995 World Citizen watch radio shack battery is twice as small and it runs for 4 years at a time...
Click to expand...

Yeah, that's right because your watch radio can do the same amount of tasks as the Apple Watch.

Getting 18 hours of battery life out of something this small considering how much it can do is impressive.

Does the display not revert back to displaying the time on it's own?

Not sure I get your question.

If the display were always on(which is what I was replying to) then people would be able to see anything your watch was doing, like texts coming in, etc.

I've never once had a watch stolen off my wrist. Let's not be ridiculous here.

I didn't think anyone would expect that to be the case, I would presume, after a 5 or 10 second period the screen would default back to the time. Otherwise you would always have to press a button to see the time, which seems silly.

I am sure folks have never had their phones stolen from them either.

You would? :rolleyes: But then you wouldn't have an Apple watch, would you? I mean anybody can pull TDP and battery capacity curves off a chart and spout predicted usable life. But it really means nothing if not put into the context of the final product, uses, and capabilities. You haven't even lived with tactic feedback for any length of time and you are willing to cast overboard one of AWs key design elements? Really?

Phones haven't have haptic feedback? Huh?

Your Citizen watch is a computer running software, Bluetooth, wifi constantly?

No? Then your comparison is moot.

The Apple watch has GPS/WIFI? No?

The times come not only from multiple recent online comparisons, but more importantly, from my own experience. I've bought and tried out all the watches (except the Asus and Apple, which haven't arrived yet) to see for myself. I didn't trust old reviews or second hand reports.



Oh sure. For example, some of those watches keep their display on all the time, and still get 48 hours.

The point was not a direct comparison, btw. It was to demonstrate that even among other watches, more battery can make a startling difference.



I'm sure they did. Doesn't change the fact that more battery = more run time, for ANY situation or device.

I suspect that many people would love for their Apple Watch to have a larger battery than the current quite small capacity one.

This chart is unscientific and not to be trusted, simple as that. Everything else is just your spin. Your telling me you were actually testing the EXACT same thing from watch to watch... Totally Improbable.

I read those reviews too btw. Most finished with enough juice to easily go to 24h every day. No mention by you. The fact the 18h applies to the smaller watch, which undoubtably still has a much smaller battery than the other watches... No mention by you. Your whole list had an obvious slant.

A side by side all day test of the watches on a rig, set up exactly the same, doing the exact same thing would be the only way to get a true measure. Even there, it would be possible that a watch has fantastic performance if the pairing phone is next to it, and crap perf if it is 50 meters away. Testing will be a much bigger challenge than your pseudo-test.

I agree.

Although, from their viewpoint, it does prevent them from being able to make money doing some repairs to Apple Watches.

(At first I was going to say it's not worth repairing a smartwatch, because they're pretty inexpensive. Then I remembered that people are actually paying a pretty hefty amount for an Apple Watch, especially the stainless steel models.)

If that's a problem, you can either turn off the always-on mode, or change the settings to not display preview cards automatically.

Nobody said any of that. Calm down and stop posting strawmen.

Everyone else seems to have realized that it was a chart with very broad ranges, posted simply to point out that battery size can have a big effect on usable life. It's not meant as a direct or detailed comparison, except as far as battery size goes.

I'm sure we'll be seeing the kind of comparison tests you're talking about pretty soon.

If by small, you mean its battery capacity, then yep. Heck, this button cell battery has the same Watt hour output (3.0V x 260 mAh) as the battery in the Apple Watch (3.8V x 205 mAh):

Even better. Just make a slot I can keep pumping these babies in like quarters in a Pac-Man machine and I'd never have to charge the watch.

The coin cell battery is not rechargeable, so its volume & weight are not valid for comparison with the battery in the watch.

After seeing the full tear-down on this watch, I'm really not that impressed by the technology or engineering. The internals are crude by comparison to similar products made in Japan and Switzerland, and even other Apple products like the airport express.
