Infinix Smart 2 HD Rear Back Battery Door With Side Buttons - Black, Verified Fit

About this product

This rear back body casing is the back door that covers the battery compartment, built as a direct replacement for the Infinix Smart 2 HD, a 2018 Android Go device with a 6.00-inch IPS LCD display at 1440x720 resolution and a plastic-bodied chassis measuring 159.5 x 76.1 x 8.3mm and weighing 155g. It replaces a cracked, scratched, or missing back door and comes pre-fitted with side buttons so the power and volume controls are ready to snap into place along the housing edge. Because the Smart 2 HD ships in four factory colors — Sandstone Black, Bordeaux Red, Serene Gold, City Blue — this Black variant is intended for units that were originally black or for anyone standardizing on a matte black finish.

• Molded to the Smart 2 HD's exact 159.5 x 76.1 x 8.3mm footprint and 155g weight distribution
• Pre-attached side buttons aligned to the phone's power and volume rocker positions
• Cutout positioned for the single 8MP rear camera module
• Open channel for the micro USB charging port at the base of the housing
• Clearance for the 3.5mm headphone jack and speaker grille
• Finished in Black to match or replace the Sandstone Black factory option

How it fits your Infinix Smart 2 HD

Because the Smart 2 HD carries a plastic body rather than a glass or metal back, the original back door snaps onto the frame using plastic clips rather than adhesive — this replacement housing is molded to match that same clip pattern so it seats flush against the 8.3mm-thick frame without gaps. The camera cutout lines up with the phone's single 8MP rear lens, positioned in the upper section of the back door as on the factory unit, and the housing leaves the micro USB port at the bottom edge fully open for charging at the device's native 5W. The pre-installed side buttons correspond to the power and volume keys on the right edge of the frame; they need to be seated into the internal button contacts during installation so they respond with the same tactile click as the original door. This back door does not extend to the front of the phone, so it has no effect on the 6.00-inch IPS LCD display or its 1440x720 panel — that surface is only protected if you're separately running a screen protector.

What you should know

This listing covers the Infinix Smart 2 HD only — it is not compatible with the Infinix Smart 2, Smart 2 Pro, Smart 3, or Smart 3 Plus, which use different chassis dimensions and button layouts despite the similar model names. This is a housing/back-door replacement, not the 3500mAh battery cell itself; the battery is not included and must be reused from your existing phone or sourced separately. The casing restores the phone's original closed-back appearance and reseals the battery compartment, but it is a like-for-like structural replacement rather than an added layer of drop or impact protection — it carries no drop-rating or ruggedized-case claim. Fitting a rear back door requires opening the phone, disconnecting the battery, and transferring the side buttons and internal clips correctly; because the Smart 2 HD's MediaTek MT6580 processor and 1GB RAM board sit close to the rear housing, we recommend professional installation to avoid flexing the motherboard or damaging the dual Nano-SIM tray, and opening the device yourself may affect any remaining manufacturer warranty.
