DIY Google Pixel 3a Battery Repair Guide

To start, we need to have the right tools to proceed with the repair, which you can find in the description. First, turn off the phone and take off the sim tray, and then the lcd screen removal from the front.

To remove the lcd, 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 hair dryer. Around the screen edges until the pasted adhesive becomes soft. Once you feel the heating is enough, use a suction cup to leave the screen. Then, insert a plastic car pry tool or something similar to cut the adhesive around the lcd screen.

Lift the screen gradually and disconnect the connector plug by undoing two screws. And remove the metal shield. There’s an adhesive strip on top of the connector. It is missing from this device. If you have the sticky, peel it off and place it while connecting the lcd screen.

Next, take out the mid-frame plate by undoing 14 screws, and then by using a plastic car pry tool or triangular picker, move on the phone to release the mid frames clips.

Next, lift the mid-frame by the bottom rise to 45 degrees, release the proximity sensor, and then take out the frame.

Next, on the body, disconnect the battery connector. Write four sensor flex connect and both ends on the main flex cable.

Next, take out the main flex and disconnect the left four sensor plug in the board.

Next, move the sensor plug aside and take out the broken battery by peeling the adhesives. There are two adhesive tabs on this phone for the battery, top left and bottom right. Gently peel the adhesives by holding the phone. Be careful. You might end up with damaging four sensor flex cables.

Once the battery adhesives have come out, use a pry tool to gently lift the battery and slowly take it out.

Next, take out the broken battery and replace the new battery on the body with adhesives.

Next, place the main board flex and connect it by both ends and then connect the left and right four sensor plugs and the battery.

Next, connect the proximity sensor and place the mid-frame by adding 14 screws here. We take out the frame proximity sensor and then connect it to the logic board. When placing the mid-frame, gently pick the sensor through the opening and put it in the frame.

We are doing this to eliminate the difficulty of clicking the sensor plugged into the board while installing the frame. Also, insert the SIM tray.

Next, place lcd screen on the body and then connect the lcd plug and add the shield by inserting two screws and also the tape, which we don’t have, but you may have.

Before installing the lcd screen, ensure it has enough glue on it. If not, use b7000 glue on your double-sided lcd screen adhesive.

Finally, we are adding a binding place to time the lcd screen with the body. Leave it for some time and remove it. On the other hand, you can use rubber bands and leave them for some time. I hope you have enjoyed the battery replacement guide. Let us know if you have any questions.
