DIY Huawei P20 Pro Battery Repair Guide

Before Starting, 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 out the sim tray, and then follow with the back cover removal.

Here, we are using a heating pad to remove the back cover. Place the back cover side on the heating pad and, select the mobile phone heating option, and leave it till the heating completes.

Alternatively, you can use a heat gun or hair dryer. Once you feel the heating is enough, use a suction cup to lift the back cover in between, insert a plastic card pry tool, and gently cut the adhesive around.

While you are taking off the back cover, be gentle. The flash sensor is attached to the back cover to unplug the connector, move the back cover to the left-hand side and undo the plug.

Take out the back cover and take out the board frame with the pad by undoing screws undo 9 screws and lifting the frame using a pry tool.

Next, unplug the battery and main flex connectors.

Next, insert the pry tool by the top left and slowly lift the battery. Be gentle in this process and pull out the battery.

Now take out the battery and, replace the new battery, and paste the adhesive back here. We are not adding any glue but adding new adhesive to the new battery.

Next, secure the main flex and battery connectors to the logic board.

Next, place the board frame with NFC by adding 9 screws.

Before installing the main back cover, make sure it has enough glue on it. If not, use b7000 glue or new double-sided backup adhesive.

Next, connect the flash sensor plug and place the back cover on the body.

Finally, we added bonding clips to fasten the back cover, leave it for some time, and remove it. If not, use some rubber bands to tighten the back cover.
