Hi everyone, Welcome back to geardo,
Today we will show you how to replace the battery on the google pixel 4a mobile phone.
To start, we need to have the right tools to proceed with the repair, which You can
find in the description.
The first step is the LCD screen removal from the front.
To remove the screen, it needs to heat gently around the screen cover edges until the pasted
adhesive becomes soft.
For this, we are using a heating pad.
Place the front screen side on the heating pad.
Select the mobile phone heating option and leave it till it completes.
Alternatively, you can use a heat gun or hairdryer.
Once you feel the Heating is enough, use a suction cup to lift the screen a little and
insert a plastic card pry tool or something similar to cut the adhesive around
the LCD screen.
Next, Lift the screen gradually to about a 90% degree angle from the top and pull out
the lcd connector bracket by undoing two screws.
Next, disconnect the lcd connector to free the screen from
the body.
Next, eject the sim tray.
Next, undo eight screws on the mid-frame plate.
Next, using a plastic card pry tool or triangle picker, move around the phone to release the
clips.
While pulling out, be gentle; cables connect with the logic board.
Pull out the housing and gently lay the back cover from the top on the surface.
Be highly gentle in this process, do not apply force to the phone or cables.
Next, take out the logic board bracket by undoing seven screws.
Be gentle with flex cables while moving
the bracket.
Next, disconnect the battery plug.
Next, disconnect the fingerprint button and flash sensor plugs from the board to release
the back cover from the body.
Next, flip the body frame and remove the adhesive tape pull tabs.
There are two pulling tabs in this model.
Next, gently grab the pull tab from a tweezer or fingers and then pull away until it slips
out from the battery.
This process will take time and be gentle and hold the phone steadily while doing
the procedure.
Next, perform the same steps to remove the other adhesive strip from the battery.
Next, flip the body and release two adhesive tapes holding the battery.
Next, gently pry out the not working battery from
the body.
Next, place the new battery with adhesive.
Next, place two adhesive tapes on the battery.
Next, Maintain the back housing to 90 degrees and secure the FIngerprint and sensor plugs
to the board.
Next, secure the battery plug.
Next, place & secure the board bracket by adding seven screws.
Next, gently slide the body to the housing from the top and then to the bottom.
Next, gently press to fasten the clips on the body with the housing.
Next, insert the sim tray.
Next, secure nine screws on the mid-frame plate.
Next, place and connect the lcd screen plug and add two screws with
the bracket.
Next, turn on the device for verification & testing.
Next, Before installing the LCD Screen, ensure it has enough glue; if
not, use B7000 glue or a new double-sided LCD adhesive.
Gently slide in the screen from the bottom and then to the top.
Slightly apply pressure on screen edges.
Finally, we are adding bonding clips to fasten the lcd screen.
Leave it for some time and remove it; if not, use some rubber bands to tighten the screen
to the body.
