Xiaomi Poco X3 NFC Rear Back Housing Replacement Battery Door - Grey

About this product

This is a rear back body housing (battery back door) built specifically for the Xiaomi Poco X3 NFC, replacing the original plastic back panel when it is cracked, scratched, or removed for a repair. The Poco X3 NFC ships with a glass front and plastic back and plastic frame, and this housing matches that same plastic construction and the 165.3 x 76.8 x 9.4mm body so it seats flush without added bulk. It comes in Grey, mirroring the Shadow Gray finish Xiaomi sells alongside Cobalt Blue, so a repaired unit still looks close to stock rather than mismatched. This is a structural replacement part, not a snap-on case, so precision at the camera cutout and button openings matters more than it would with an accessory.

• Molded to match the Poco X3 NFC's plastic back and plastic frame build
• Cut for the quad rear camera housing (64MP + 13MP + 2MP + 2MP array)
• Sized to the exact 165.3 x 76.8 x 9.4mm chassis, keeping the phone's 215g balance unchanged
• Grey finish matched to the Shadow Gray color option
• Openings for the volume rocker and power button on the frame edge

How it fits your Xiaomi Poco X3 NFC

Because the Poco X3 NFC uses a plastic back and plastic frame rather than a glass or metal unibody, the back door is designed to be removed and reseated during a screen or battery repair, and this housing is cut to the same panel lines so the camera bump for the 64MP + 13MP + 2MP + 2MP quad array sits centered and flush once installed. The perimeter follows the phone's 165.3 x 76.8 x 9.4mm frame, so the volume and power buttons, the USB-C charging port at the base, and the 3.5mm headphone jack all line up with their original openings rather than needing to be forced. It does not extend to or cover the 6.67-inch IPS LCD display up front, which is protected separately by the phone's Gorilla Glass 5 layer; this door only addresses the rear housing. Since the Poco X3 NFC carries an IP53 splash-resistance rating from the factory, note that any rating tied to seal placement and adhesive is set by Xiaomi at the time of manufacture, and reinstalling a back door on your own does not carry a claim to preserve that same seal.

What you should know

This housing is made for the Xiaomi Poco X3 NFC specifically; it is not intended for the standard Poco X3 (non-NFC variant with different internals), Poco X3 Pro, or Poco X3 GT, and you should confirm your exact model before ordering since back panel cutouts and camera housing shapes differ across those variants. This is a cosmetic and structural rear panel, not a shock-absorbing case: it restores the outer shell and camera surround but does not add drop protection or scratch resistance beyond what the original plastic panel offered. Fitting a replacement back door means opening the phone, so this is a repair-grade part best handled by someone experienced with phone disassembly or by a professional technician, and installation can affect any remaining manufacturer warranty on your device. We recommend disconnecting the battery before removal and reseating any adhesive strips or seals correctly to avoid dust or moisture ingress given the phone's IP53 rating.
