Disassembly/Repair of the mobile device Xiaomi 13 Lite (Xiaomi 13 Lite 2210129SG) with each step description and the required set of tools.

⚠️️ Before disassembling, do not forget to turn your phone off.

First of all, we need to remove the card tray. To do this, we use a special tool, insert it into the hole and carefully push out the card tray.

⚠️️ If the tray does not come out well, we can additionally use tweezers.

We move on to heating the back cover. For this we use a heating mat, you can use a hair dryer. We heat the surface of the back cover to about 70° C or 160° F.

And after 5 to 7 minutes, we can move on to detach the back cover. We use a thin plastic film to detach the back cover. We find the right place where we can pass our plastic film.

In our case, we can't pass the film under one of the corners, but we can pass the film in the area of the side buttons.

⚠️️Carefully, without hurrying, we work with the tool. It is necessary to be careful in the area of the side buttons not to damage the cables, it is necessary to be careful in the area of the cameras not to damage the lenses.

⚠️️Since the cover is curved, it will always be difficult to pass on the corners.

We have only the gasket on the back cover.

Then we need to bend aside the flashlight cable, because there is another screw underneath this cable.

Using a screwdriver Phillips 1.5 mm (PH #000), unscrew the ten screws.

And now we can carefully detach the cover that hides the motherboard. We detach the cover with a non-metallic tool.

Disconnect the two battery connectors as soon as you can. Use a non-metallic or plastic tool to avoid a short circuit.

ℹ️️ The Xiaomi 13 Lite 2210129SG model has a battery BP4E with a capacity of 4500 mAh (also known as a rechargeable battery).

Then we disconnect the connector and remove the flashlight cable.

After that we move on to removing the screws at the bottom.

Using a screwdriver Phillips 1.5 mm (PH #000), we unscrew the five black screws.

Using a screwdriver Phillips 1.5 mm (PH #000), we unscrew the two small silver screws. 

Next, we need to detach the cover with the loudspeaker.

As always, it is really important that we find the right place where we can pry and lift the cover off.

We try to detach the cover from different sides, but we don't need to force it, because once we find the right place, the cover will open with ease.

So we find the right place, open it, lift the cover, turn it over and as we can see, in order to detach the cover with the speaker, we also need to disconnect the coaxial cable connector on the motherboard.

And we remove the cover with the speaker and the coaxial cable.

After that, we disconnect the inter-board cable connector, we disconnect the fingerprint sensor connector, we disconnect the coaxial cable connector, and we release the cable itself.

And we move on to detach the sub-board. We need to also, find the right place where we can gently pry and lift the sub-board.

In one of the places, we can see the clip that holds the sub-board in place. This is the best place to hook and lift the sub-board and pull it out.

On the sub-board we have the microphone, the charging port, and the card holder on the back side.

We disconnect the inter-board cable connector, display cable connector, coaxial cable connector and bend the cable aside.

And we move on to detach the cameras on the motherboard.

First we disconnect one front camera and as we can see, in order to unglue the heat dissipating coating, we need to detach the second front camera.

We detach the cameras and carefully peel off the copper heat dissipating coating and we put the cameras aside.

After that we can detach the rear cameras.

Carefully pry up the edge, slightly hold the cameras so they don't fly out, and lift, and remove the cameras.

If we can't detach the large main camera (because it is taped to the display frame) - we will do it later, after removing the motherboard.

And we can try to remove the motherboard.

We also need to find the right place where we can pry up and carefully remove the motherboard.

As we can see on the display frame under the motherboard, we have some thermal paste left.

Finally, we move on to detach the battery.

We unwrap two brown tabs with the letters A and B. We read the description, which tab we need to pull and which one we need to unwrap.

And as the description makes clear to us. We should unwrap the tab with the letter B, which is located in the middle - to the side as much as possible, so that it does not interfere with us. And the wide tab, which is located on the edges with the letter A, carefully pull upwards.

And, we pull the tab with the letter A upwards and detach the battery.

As we can see, under the battery we have a transparent protective coating, which protects the inter-board cable.

ℹ️️ In the display frame remained: the earpiece speaker, fingerprint sensor, coaxial cable, and vibration motor.
