the iPhone 4s is well on its way to
being ancient in technology years but
that doesn't mean it can't work if
you're still rocking an iPhone 4s and
its original battery it might be time
for a boost so today I'm going to show
you how to replace the battery in your
iPhone 4s for this repair you're going
to need an iPhone 4 5-point pentalobe
screwdriver a phillips triple 0
screwdriver plastic opening tools and an
anti-static project tray this is just an
overview so be sure to check out the
step by step guide on ifixit.com when
you do your repair when you're ready to
reassemble your phone we recommend
working backwards on the same guide
first step is removing the pentalobe
screws on the bottom of the phone on
either side of the charge port once
you've done that and organized your
screws on a magnetic mat or tray turn
your phone over and pop off the back
panel to do that we're just going to
hold it in both hands and use our thumbs
to release it and lift it from the phone
now you can see the battery there's a
bracket attached to the connector and
it's held in place by a couple of screws
let's remove the two Phillips screws and
then get to work on the connector use a
plastic opening tool to gently detach
the battery connector from its socket
the battery connector comes off
vertically from the logic board do not
apply force to its sideways pay
attention to the pressure contact
underneath the top screw of the battery
connector this may come loose while
prying the battery connector from its
socket now that the battery is
disconnected we can take it out of the
phone to do that we're just going to
insert the edge of our plastic opening
tool between the battery and the outer
case then run a plastic opening tool
along the right edge of the battery two
completely separate it from the adhesive
securing it to the outer case now we can
use the clear plastic pull tab to peel
the battery off the adhesive securing it
to the iPhone and lift it right out
