Although Apple regularly makes improvements to its smartwatches, improvements to models introduced last fall have been less than expected. Although the Apple Watch 9 includes an S9 multiprocessor unit, the power of the processor can hardly be seen in everyday uses since the introduction of the Apple Watch 6 three years ago.
The American company explained that it has increased the level of graphics by a third, and this can be seen in applications such as the Maps and Weather application, which has become somewhat faster, but in other applications the user will not notice any difference.

Architectural 5 nm
It is also disappointing that the new manufacturing technology is not noticeable when it comes to power consumption; the S9 is no longer made with a 7nm architecture, but is now made with a 5nm architecture, which means that there are far more transistors on the same space, and this actually leads to lower power consumption. But in practice, the user has to recharge the battery after about 18 hours because the higher efficiency of the S9 processor does not extend the battery life as expected.

Ultra-bright display
The new Apple Watch 9 currently includes a very bright screen, it has a brightness of up to 2000 jandelas (the unit of measurement of screen brightness), so it is twice the brightness of the Apple Watch 8, and the same brightness as the Apple Watch Ultra from last year. The advantage of the Apple Watch 9 is that it works at a high brightness outdoors, so the user can read the contents of the screen even in sunlight.
The Apple Watch 9 has two new features that need some additional power; as the new Apple Watch no longer needs an internet connection most often to execute Siri commands, it can process inputs for some functions locally such as setting an alarm, calling the app, or starting a workout. The new Double Tap gesture may also consume some energy. This new function is intended to help the user in some situations when he can only use one hand. With the launch of the brightest screen, the most efficient processor and the new double-click function, the American company has not only made adjustments to the exterior of the new Apple Watch 9.

In summary, the Apple Watch smartwatch is still the standard for iPhone owners, but it is available at an expensive cost, especially when choosing a model made of a 45mm stainless steel body, and the smaller model comes with an aluminum body.
