hey guys Scott with iFixit here and
today we're gonna talk tear downs
specifically all the Apple tear downs
we've done recently starting with the
iPhone 8 and iPhone 8 plus while the
opening procedure was pretty much the
same as the procedure in the iPhone 7
the iPhone 8 and 8 plus had plenty of
interesting things for us to find the
iPhone 8 lost some tripoint screws in
the display cable bracket but before we
got too excited about Apple removing
these pesky screws we found one down in
the top tech engine bracket and in both
the display bracket and the topic engine
bracket in the iPhone 8 plus the battery
adhesive strips have been changed from
two full-length strips to for shorter
tabs most likely to avoid being overlaid
on the wireless charging coil speaking
of batteries the batteries and both
phones lost a little capacity the iPhone
8 came in at six point nine six watt
hours down from the seven point four
five watt hour battery in the seven in
the eight plus at a ten point two eight
watt hour battery down from the 11.1
watt hour battery in the seven plus
however Apple does claim that battery
life should be about the same as the
previous generation the Apple watch
Series 3 didn't have any surprises for
us during the opening procedure as it
was remarkably similar to the series two
inside the watch we found a ton of tiny
tripoint screws a battery with a four
percent increase in capacity support for
qi wireless charging and a whole new
section of RF chips surely responsible
for handling two added LTE functionality
interestingly after the teardown we dug
into that non LTE version of a series
three and found some changes including a
battery with slightly lower capacity and
a taptic engine with a different style
of connector the non LTE version had
coiled copper connectors that formed
copper to copper contacts while the LTE
taptic engine was soldered directly onto
the board we were expecting the new
Apple TV 4k to be nothing more than a
board in a box but once we got in we
found a new addition to the Apple TV
family a fan all that 4k HDR playback
must come at a thermal price we also
found an upgraded processor the Apple TV
4k has the 18x fusion processor a big
improvement from the a8 found in the
fourth generation Apple TV all of these
teardown generated some questions from
you guys and hopefully we've got some
answers first up
what's the reason that necessitated
reducing the capacity and the batteries
of the iPhone
that's a good question in my opinion
Apple reduced the battery capacity to
make room for new internal components
such as the qi wireless charging coil
now that being said apple says that
battery life will be about the same as
it was in the previous generation so
performance probably will not be that
different the layout of the iPhone 8
looks pretty much the same as the layout
in the iPhone 7 can you use an iPhone 7
display in the iPhone 8 so we actually
did some testing on this and found that
the LCD from an iPhone 7 does work on
the iPhone 8 however the digitizer from
an iPhone 7 does not work on an iPhone 8
so therefore it's not a perfect fit I
heard that Apple was suing Qualcomm
after the increased royalty fees for
using their chips does the Apple watch
Series 3 still use Qualcomm chips or did
they switch to Intel we actually found
Qualcomm chips on our iPhone 8 or iPhone
8 plus and our Apple watch series 3
which does suggest that Apple and
Qualcomm is still pretty reliant on each
other and lastly with everything upside
down down under how'd you guys keep all
the electronics from falling out oh hi
You cheeky Mike just kidding it turns
out gravity's actually upside-down in
Australia as well so we didn't really
have much of a problem we have a ton of
tear downs coming up soon so make sure
that you subscribe to our Channel I'll
see you next time
