Apple Watch Series 4 teardown reveals big changes on the inside

Apple Watch Series 4 teardown reveals big changes on the inside

While Apple seems content in holding the line on Apple Watch battery life, Samsung is heavily touting the 4-day battery life on its competing Galaxy Watch (we saw 5 days our own testing). iFixit seems to reckon that Apple if could manage to shrink down the massive Taptic Engine, it could squeeze in a larger battery.

The ad ends with the line "there's a better you in you", clearly leaning on the fact that wearing an Apple Watch will somehow make you more active than you were before. But it is enabled only for people aging 65 or older when they set up the Apple Watch and the iOS Health app. The watch can now automatically detect falls using the next-gen gyroscope and call emergency services. You'll get a tap on your wrist and an audible alarm, plus an on screen alert saying "It looks like you've taken a hard fall".

AppleWhat is fall detection on Apple Watch? One of the most talked about however is its Fall Detection capability, which Apple claims will detect falls and allow the user to contact emergency services if needed.

However, if for some reason you can not respond to your Apple Watch, and you're immobile for about a minute, it will begin a 15-second countdown while vibrating and sounding a progressively louder alarm. If you want to know more about the feature, including how to turn it on, read on.


Overseas customers looking to get the new Apple Watch, and keen on the new ECG feature shouldn't worry, though.

While talking about the Watch Series 4, Apple also explained about one of the key features - Fall detector. But on harder surfaces it worked fine.


But for all that the Apple Watch does, it's still fun to accessorize. Its speaker is also 50% louder than the Series 3.

The Apple Watch 4 is actually slimmer than its predecessor by 0.7 mm.


Apple said all falls are recorded in the Apple Health app (unless you reply that you didn't fall when your Apple Watch asks).
