The collision detection system recognizes when the wearer has been involved in an accident. If the watch detects a sudden blow, the 4G version can independently call emergency services or the watches can use an iPhone connected via Bluetooth.
Moreover, there is very little news to report about the 8 Series. We had hoped that battery life would be improved, but that is not the case in practice. We got about 30 hours with the Series 8 in normal daily use with the screen always on and an hour of sports using GPS.
The Watch Ultra is by far the largest of all watches to date. Fortunately, this is not just a show, because Apple has equipped the watch with a larger battery, with which the Ultra lasts much longer than its smaller brothers.
This watch has all the features of the Series 8. Plus, it has a number of extras that other Apple watches don’t have or that work better on the Ultra. For example, the watch has not one but three microphones. In practice, we already hear the Ultra sound better than the Series 8, but there’s no difference between day and night.
The same goes for larger speakers. Apple claims these sounds are 40 percent louder than the speaker on a regular Apple Watch. The difference is audible, but not significant. Its sound is still much lower than the speakers of modern smartphones. Therefore, it is difficult to make hands-free calls in a room with a lot of ambient noise.
