There are lots of predictions about the next Apple Watch, Series 4 announced in September 2018 at rumor factory. I will upgrade the possibilities and probabilities.
The most attractive guess I have seen is related to physical design and health monitoring. However, there are some intriguing side functions common to Intel that are collected. So let's dig it up.
Apple Watch physical design
One rumor I discounted is rounded. The round display was outdated and was born in the era when the hands of the watch and the clock were rotated. Modern smart watch has to display a lot of graphics and text data, only rectangular display makes no sense.
That is, Apple maintains the same basic dimensions in the four models of Series 0, 1, 2, 3. Since the design of Series 0 was frozen in 2014, there have been many changes in semiconductor technology. Even though Series 4 is thinner, it knows all that it has a much longer battery life than any other person. How can you do it?
You will not take as much to look like so much cooler in the way of 1 mm or 2 mm shaving from the thickness of Apple Watch. However, if you can reduce the size of the logic board and related circuits and sensors, if the size of the case is a bit larger, you can extend the x and y dimensions of the battery. (Or, it is supplemented with a watch band, which will be explained later.) In other words, the capacity of the battery: [new] (X + dx) * (y + dy) * (z – dz) > [old] Catsyz.
Of course, if the case is large, the larger the display, the higher the power consumption will be. That is, if Apple has not found a display technology that consumes less power than OLED. Apple may be doing with MicroLED. It probably is more than offsetting the modest ones …
