I didn't write the article. And I never said anything about the Apple watch and battery life other than to address the fact that more than 1 solid day is possible.
Got a tip for us?

Not possible if you add the GPS and cell communication, which you mentioned in the same message. It's not even close to being possible with either of these (and your using battery space too with those chips and antenna, so there is a trade-of).
Making the second day was always possible, it's possible with most watches now if you use it in a controlled way. The question is, why would you want to use them in a controlled way? I know people who get an insane number of calls, notifications for emails, text msg, calendar, etc, in a day, those people will not make it with a current phone like the 360, not even close.
You realize you're just stating your opinion. There's no use case for the new Sony watch with these elements activated. And the Apple Watch isn't being sold yet.
Semantically, your comments are quite flawed.
324 ppi
Is there an official info on detailed watch dimensions?
Many ppi calculations here take the device dimensions as screen dimensions, which is obviously a very inaccurate approximation.
I've found an estimation for the 42mm screen by Paul Sprangers.
24.3 mm x 30.5 mm (1.54 inch diagonal)
putting this value into the dpi calculator gives 324 ppi.

Quite a convincing argument (plus the comments section in your link provides much other food for thought).

Its not flawed at all because battery tech / GPS & Cell tech / Screen tech and SOC tech don't allow it in a small format.
That's NOT AN OPINION. You can bank on it.
Sony doesn't produce its own SOC and software, so right there they start at a disadvantage with Apple. There are no miracles, especially for a company which has been threading water for so many years now.
If you use the GPS 30 minutes and then have to closely watch your usage the rest of the day, well that's expected and yes, that kind of use is entirely possible right now...
Maybe there is a public for that kind of thing.... But then again Sony has bet on so many wrong horses that I wouldn't put any money on it.
Reading comprehension failure on your part, followed by you trying to put words in my mouth.
Let me rephrase that for you: The thing that a lot of people already use (that is technically similar to a digital crown) is called a mouse scrollwheel.
Is that better or will you try twisting my words again?
No need for twisting your words or putting words in your mouth - - I can just directly quote your original post:
Of course you are free to correct your error by rephrasing your original statement...
...my comments in this thread were simply to point out your original mistake.
That is NOT correct!
According these calculations, the watch dimensions are:
The body: 36.2 mm x 42 mm
The screen: 24.3 mm x 30.5 mm
30.5 mm = 1.20 inch.
So, to calculate the ppi, one should divide the pixels by height.
By your speculations, 780/1.2=650 ppi! (no such display is even created yet!)
390/1.20=325 ppi! (well within the range of Apple Retina products)
Now you tell me, which one makes more sense?
With x2 Retina, the content size will be 195x156.
Number of Pixels Big = 121680, Small = 92480
(4mm bezel), Big : 1.43 = (34*27.2), Small 1.12 (30*24)
(3.5mm bz) , Big : 1.48 = Small 1.16 (30.5*24.5)
(3mm bezel), Big : 1.52 = (35*28.2), Small 1.20 (31*25)
(2.5mm Bz), Big : 1.56 = Small 1.25
Which means PPI would be
4mm Big 292 Small 288
3.5mm Big 287 Small 282
3mm Big 282 Small 278
2.5 Big 280 Small 272
Not sure the Bezel is exactly the same for both watches, the smaller one probably has a 0.5mm difference in Bezel with the big watch for aesthetic reasons.
If its 3mm for the small one (1.2 square inch), you get 1.48 for the large one.
Thus the PPI would be 287 (Big one), 278 (Small one).
The reason for not wanting a sky high PPI in a smart watch is twofold, first, it is on your wrist, so the average distance is probably closer to the Ipad one.... Secondly, a large pixel count burns battery. You can't make the screen larger or the watch thicker to compensate so you have to design the device with severe energy limitations in mind.
That's why most smart watches have pixel counts in this range. Which is "retina" as initially defined by Apple. In this case, its mostly battery considerations that dictates this resolution.
