Infinix Smart 6 Purple Rear Battery Back Door Casing Replacement - Verified Fit

About this product

This is a replacement rear back body casing (battery door) made specifically for the Infinix Smart 6, a 2021 budget phone with a 6.6-inch IPS LCD screen and a 164.8 x 75.8 x 8.5mm plastic frame and back panel. It is designed as a direct swap for a cracked, scratched, or discoloured original back cover, restoring the phone's outer shell without replacing the whole device. The cutouts and mounting points are shaped to match the Smart 6's factory layout, including the rear camera module and the speaker grille, so the panel seats the way the original plastic back does.

• Matches the Infinix Smart 6's 164.8 x 75.8mm footprint and 8.5mm body thickness
• Cutout aligned to the 8MP + QVGA dual rear camera housing
• Purple finish as an alternative to the stock Polar Black, Heart of Ocean, and Tranquil Sea Green colours
• Same plastic-back construction as the original Smart 6 body
• Openings for the speaker grille and microphone position as on the stock back door

How it fits your Infinix Smart 6

The Infinix Smart 6 weighs 189g and carries its 5000mAh battery under a plastic back panel measuring 164.8mm tall by 75.8mm wide, and this replacement door is cut to that exact footprint so the phone's weight distribution and in-hand feel stay the same after the swap. The camera cutout lines up with the 8MP + QVGA rear camera pairing on the top-left corner of the original back, and the panel leaves the micro-USB charging port at the bottom edge fully clear, along with the side-mounted volume and power buttons. Because the Smart 6's IPX2 rating is not a certified seal (splash resistance only, unrated), this back door is not designed to reproduce or restore any water resistance — it's a physical shell replacement, not a gasketed component. The purple finish sits on the same plastic substrate as the factory colours, so it holds a similar surface texture and catches light in a comparable way to the original back.

What you should know

This casing is made for the Infinix Smart 6 only — it will not fit the Infinix Smart 5, Smart 7, Smart 8, Hot series, or Note series, since body dimensions and camera placement differ across those models. It is a cosmetic and structural back-panel replacement: it restores the phone's outer appearance and closes the battery compartment, but it does not include a battery, does not add impact or drop protection beyond what the original plastic back offered, and does not carry any water-resistance rating of its own. Fitting a new back door means opening the phone's rear housing to access the battery and internal frame, which can affect any remaining manufacturer warranty on the device — if your Smart 6 is still under warranty, check the terms before installation. Because this involves prying near the battery compartment, we recommend having it fitted by a phone repair technician rather than doing a first-time DIY install, to avoid flexing the battery or damaging the retaining clips.
