    • There are no exterior screws. The top and bottom panels of the rear case are made of plastic, but cannot be separated from the rest of the case.

    • Prying the body of the phone out of the rear case is fairly straight-forward, the plastic clips holding it are flexible enough to bend without breaking, and are not too strong.

    • Fingerprint sensor cable connects the rear case to the interior of the phone, but is long enough that you can safely disconnect it without damaging it.

    • Fingerprint sensor is the only component left in the rear case.

    • Fairly easy to remove by pushing through the back of the case.

    • First layer of removable components includes: loudspeaker assembly, antenna, buttons, vibrator bracket, front- and rear-facing cameras.

    • Next out: interconnect cable and antenna interconnect.

    • Next out, daughterboard with charging port.

    • Motherboard removal, the only component removed from the motherboard is a rubber duct for the microphone.

    • The main board is pretty minimal, but the headphone jack is soldered on, making jack replacements expensive.

    • Final components off of the display assembly are the vibrator and earpiece speaker.

    • The fused, midframe-mounted display assembly is last out, making fixing a broken screen a more expensive and time consuming repair.

    • The Xiaomi Redmi Note 3 earns an 8 out of 10 on our repairability scale (10 is the easiest to repair):

    • Despite no external screws, the rear case is fairly easy to remove.

    • Battery is easy to access and remove.

    • Modular design with charging port on its own daughterboard means many components can be independently replaced.

    • Display assembly is a single fused component, that requires disassembling the entire phone to replace.

    • Manufacturer does not provide user-accessible repair documentation.

Thanks for this guide. Almost Identical to a Galaxy Note 3 screen replacement. A lot easier than I though it would be.

Thank you so much for posting this teardown!

My Redmi Note 3 Pro developed a charging problem, and this post gave me the basics I needed to replace the usb daughterboard.

The phone was acting weird... When plugged in to a charger, the led indicator did not light up. I tried 7 different chargers and cables including 0.5, 1 and 2amp units. What was strange was that when it was plugged into a dual or quad port charger, any other devices stopped charging immediately. Those with led indicators switched off when it was plugged in.

I hoped it was a short circuit or fault in the usb port, which I learned here was replaceable. So I ordered the part on eBay and replaced it myself at home. All up it cost me $11 to fix my phone, and it is now working as normal again.

I'd like to add that one of the screws holding the speaker assembly is hidden under a tiny sticker, and the assembly and usb daughterboard are both also held in place by glue or double sided tape. Lift carefully and they come off quite easily.

Where did you buy the usb charging port board (daughterboard)? I have the exact same problem, except the turning off of charging on devices only happens when I bend the charger down slightly. Do you have any problems with mobile data/ calling/wifi and or bluetooth?
