Apple Watch Series 5 Teardown Indicate Minor Changes Have Made To Some Parts Repair site iFixit’s teardown on Apple Watch Series 5 indicates that the wearable device is similar to its predecessor in terms of internals. Although, Apple has made enough minor changes that many parts are not interchangeable, for example, the redesigned connectors on the taptic engine, display and battery.
Moving onto the main highlight of the Apple Watch Series 5, Always-On display, which allows you to view the time without lifting your wrist or tapping the screen, it’s terribly difficult to get an Always-On screen for a sophisticated device like the Apple Watch. iFixit found that in order to achieve an Always-On experience, Apple uses advanced display driver chips, improved power management chips and ambient light sensors.
Not only that, the battery capacity of the Apple Watch Series 5 has also managed to improve, although hardly any improvements have been made. In the figure below, the Series 5 is on the left and the Series 4 is on the right. The Series 5 has a battery capacity of 296 mAh and the Series 4 has a battery capacity of 291.8 mAh.
