DIY Poco X2 | Xiaomi Redmi K30 BN46 Battery Repair Guide

Before Starting, we need to apply some heat. You can use a heat gun hairdryer or a heat mat. But make sure you don’t put too much heat on the phone and try to use the heat in the area with adhesives that are usually there around the frame or sometimes around the camera lens.

Also, once the heat is applied, you can use a suction cup to pull the back cover up a little bit to create a space where you can insert your pry tool.

Next, we are using a plastic card to cut through the adhesive that is holding up the back cover well.

After unscreening, we will use a spudger tool to disconnect the main flex LCD and get it out of the way.

In the bottom of the battery, you can see there is an adhesive that has a black slab, which you can catch and start pulling. Remember always that try to stretch it as slowly as you can.

Because a simple jerk can break it, and then it will be a problem for you to remove the battery.

You might have to end up using some chemicals. And pick up the battery, which can bend the battery that will really make a mess.

Once the battery is removed, you can use double side tape glue or these additives to install it back.

Just get the mean flex cable out of the way for the LCD to install it back. Make sure that it is sitting properly from all sides.

It is recommended to put all the connectors back on before you try to turn on the phone, all the LCD batteries, everything.

Now just go back and reverse all the things you have done, install the shield put all the screws back make sure they are all in their place.

Next, all the screws have to be back in their place.

You can use a double-sided tape or glue and put it around the corners. We should leave it there for a while.
