Apple Watch Series 3 teardown reveals minor changes, mostly LTE related

The new Apple Watch Series 3 touts LTE-connectivity. Interestingly, it uses its screen as an antenna. The good news is that this did not negatively affect the watch’s repairability. In fact, iFixit rates it at 6/10, same as the Series 2.

Not much has changed on the inside. Obviously, there’s the new Apple S3 chipset with a dual core processor and a few new chips which are probably the LTE modem and eSIM. There’s a barometer now too, to more accurately track your exercise.

Also interesting is the battery capacity – it packs 279mAh or 1.07Wh, a tiny increase over the Series 2 (which had 1.03Wh). It is a fairly big upgrade over the Series 1 battery though, 246mAh or 0.93Wh. (the Series 1 remains on sale, while the Series 2 has been discontinued)
