⚠️️ Before disassembling, do not forget to turn your phone off.
Disassembly/Repair of the mobile device Xiaomi POCO X5 (Xiaomi POCO X5 2111317PG) with each step description and the required set of tools.
Step 2. Remove the tray
Use the ejection tool (aka Needle) or Paperclip. Push the tip all the way into the hole until the tray ejects, and then pull the tray of SIM and Memory card (Micro SD) out.
⚠️️ Pay attention! The tool must be inserted into a hole on the edge of the phone's housing. Do not press too hard. It may break the tray eject mechanism.
Step 3. Open the back cover
We recommend using a special heating device such as a separator machine, heat gun, or heating mat. It will simplify the process. You can use a home hairdryer, but you will have to make a nozzle by hand or have a suitable one in the kit to gently heat and concentrate the heat flow in the right place.
ℹ️️ The surface of the back cover must be heated to soften the adhesive underneath. The approximate heating temperature is 50° C / 125° F.
Use a thin plastic film or pick for separation. To facilitate the process, you can use isopropyl alcohol. It is often the most difficult to pass the tool between the parts to be divided. Choose the far edge from the FFC cables or buttons.
Do not use a lever or any force for separation that could damage the elements inside.
Step 7. Disconnect the battery connector
Disconnect the battery connector as soon as possible. It is better to use a non-metal or plastic tool to avoid any damage.
ℹ️️ The POCO X5 model has a battery BN5J with 5000 mAh capacity (aka rechargeable battery).
Step 11. Open the middle cover
Pry over the edges. Move an opening tool along the edge detach the clips and remove the middle cover with transmission lines and pads for antenna. The middle cover protects the printed circuit board (PCB).
Try to lift the cover by the edges and don't push anything too far inside, so as not to accidentally break or short-circuit anything on the circuit board.
Step 12. Unscrew one screw
Using a Philips 1.5 mm screwdriver (PH#000), unscrew one screw holding the cover with a loudspeaker.
Step 14. Disconnect the connectors
Disconnect the two connectors of the two coaxial cables, inter-board cable connector.
⚠️️ Do not pull on the cable or pry it with a sharp tool, the connectors are pretty weak and break easily, or the cable falls out of the end (lug).
Step 15. Remove the daughterboard
Remove the sub-board. It may be glued to the frame or attached with attachments like latches or hooks, so be careful.
ℹ️️ The sub-board contains a charging port (Micro-USB), microphone, spring contacts for the speaker, vibration motor, and an antenna unit.
⚠️️ It is not necessary to insert the tool underneath when removing the sub-board. Internal components could be damaged.
Step 16. Disconnect the connectors
Pry up the display module/inter-board cable connector, and two connectors of the two coaxial cables.
Step 17. Remove the motherboard
Carefully remove the printed circuit board. There is no need to use a lever or try to reach the circuit board by force. Make sure that nothing is getting in the way or holding the circuit board.
The motherboard, also, may be attached with attachments like latches or hooks, be careful.
⚠️️ Do not bend the circuit board when removing it or push tools under it. Unbeknownst to yourself, you can damage components or cables from the inside.
Step 18. Remove the cameras
Disconnect the connectors and remove the three rear cameras and one front (selfie) camera.
Step 19. Remove the battery
We move on to removing the battery. We need to read on the brown tabs A and B which one we need to pull, and we need to unwrap all of them so the tabs don't interfere with the battery removal and don't hold it.
And as it became clear from the description, we have to pull on tab A. Gently pulling up, detach the battery. As we can see the battery is also held on by a transparent protective layer that protects the inter-board cable.
