No
sooner
has
the
Phone
16
lineup
arrived
than
the
folks
at
iFixit
start
taking
them
apart,
a
process
made
easier
this
time
around
by
the
day-one
release
of
repair
manuals
from
Apple.
The
disassembly
process
shows
the
Camera
control
is
a
real
button
that
moves,
along
with
a
flex
cable
that
likely
measures
force,
and
the
heat
sink
that
appears
positioned
to
keep
the
A18
chip’s
Neural
Engine
cool
while
it
handles
AI
workloads.
For
this
year’s
refresh,
the
base
iPhone
16
may
be
more
interesting
than
the
Pro
model
for
one
reason
—
it’s
the
first
one
using
electrically
debondable
adhesive
for
its
battery
enclosure.
As
reported
in
June
by
The
Information,
Apple
isn’t
using
the
new
adhesive
on
all
of
its
phones
yet,
but
now
we
have
a
lot
more
information
about
how
it
works
in
real
life.
The
process
described
in
Apple’s
repair
documents
matches
the
debonding-on-demand
demo
from
adhesives
giant
Tesa.
After
disconnecting
the
battery
from
the
board,
you
apply
electric
current
from
a
power
source
(a
9-volt
battery
for
90
seconds
will
do
it),
and
the
previously
glued-in
battery
slips
out
easily
enough
that
gravity
alone
can
do
the
job.
Then
to
make
the
adhesive
stick
for
the
new
battery,
it
just
needs
pressure.
Apple
notes
that
over
time,
the
time
to
release
could
get
longer,
but
on
these
brand-new
phones,
iFixit
found
that
using
20V
current
was
enough
to
undo
the
bond
in
five
seconds,
and
Apple
says
you
can
use
up
to
30V.
iFixit
also
brought
in
some
microscopic
close-ups
of
the
frame
that
holds
the
battery
and
the
machined
ridges
it
has
to
give
the
battery
something
to
stick
to.
