With the Apple Watch Series 4, Apple has debuted its new dual-core S4 chip which it claims provides up to 50 percent performance improvements when compared to the S3 chip inside the Apple Watch Series 3. Unlike iPhones, Apple Watch are slow as they are far more limited in terms of thermal and power consumption.
However, if the speed test conducted by MacRumors is anything to go by, Apple has made steady and impressive performance improvements with every new Apple Watch that it has launched so far.
The original Apple Watch Series 0 took a staggering 5 minutes and 8 seconds to boot while the Apple Watch Series 4 took 51 seconds to boot up. The Series 1 took an equally long 3 minutes 19 seconds to boot into watchOS 5.
In other tasks, like using Siri to ask questions, the Series 4 and Series 3 Apple Watch performed almost the same. However, the Series 0 and Series 1 watches took a lot of time to show up results for certain questions.
Even in app loading times, the Apple Watch Series 4 was the fastest, with the Series 3 following close behind. The Series 2 also performed relatively well despite its age. However, the Apple Watch Series 0 and Series 1 took extremely long time to open almost all apps making them borderline unusable.
Overall, the Apple Watch Series 4 the fastest of the bunch, though the performance difference between the Series 4 and Series 3 was only a few milliseconds at best. When compared to Series 2, Series 1, or Series 0 though, the difference in performance was massive, to say the least.
If you are an Apple Watch Series 0/1/2 owner, you should really consider upgrading to a newer version of the wearable for the improved performance alone. Given the small performance difference between the Apple Watch Series 3 and Series 4 though, you can upgrade to the Series 3 if you don’t mind the smaller display, thicker chassis, and other new Series 4 exclusive features. It will also end up burning a far smaller hole in your wallet when compared to the Apple Watch Series 4.
