“For the most part, the Series 2 is a typical 2nd-revision Apple device — looks almost exactly the same on the outside, but it’s super refined and a bit easier to work with on the inside,” Clapp writes. “The old standard S1 System-in-Package processing unit got upgraded to the S2, and in the process was flipped completely over. Now all of those pesky soldered connections are actually on the same side of the board as the things they connect to. Neat! Replacing many components will still require microsoldering, but will not require removing everything from the inside of the watch first. Tl;dr, this Apple watch is slightly less disposable.”
“With the glue stripped from the back of the battery, we get a closer look at its impressive specs. This cell is rated at 3.77 V and 273 mAh to yield a whopping 1.03 Whr of power. Our watch is the 38 mm—the 42 mm should feature a larger power pack. For those of you keeping score, this battery offers a full 32% increase in power over the previous generation—most likely to compensate for the addition of GPS capability,” iFixit reports. “With the Taptic Engine extracted, we inspect the antenna module found tucked away at the top of the watch. We suspect that the more complicated look of this small assembly is due to the addition of a GPS antenna. It is a tiny component, but the difference is notable when compared to the first Apple Watch.”
