Ultimately, the Redmi A3x is a slimmed-down version of the Redmi A3. For example, Xiaomi equips the Redmi A3x with the Unisoc Tiger T603, a 22 nm chipset with two ARM Cortex-A75 CPU cores running at 1.8 GHz and six Cortex-A55 CPU cores restricted to 1.6 GHz. By contrast, the Redmi A3 relies on the more powerful Helio G36. Other areas remain unchanged though, including a 6.71-inch display that resolves at 1,650 x 720 pixels with 500 nits peak brightness and a 90 Hz refresh rate.
Moreover, the Redmi A3x also has a 5,000 mAh battery that it can recharge at up to 10 W via USB Type-C. On top of that, Xiaomi will offer the device with either 3 GB or 4 GB of LPDDR4X RAM and 64 GB or 128 GB of eMMC 5.1 flash storage. Please note that the latter can be expanded with up to 1 TB MicroSD cards. Furthermore, Xiaomi has included a mere 8 MP primary camera, as well as a QVGA auxiliary lens and a 5 MP front-facing camera. For reference, the Redmi A3x measures 168.4 x 76.3 x 8.3 mm and has a 3.5 mm jack, along with dual SIM support and a side-mounted fingerprint sensor. The Redmi A3x runs Android 14 too, and should receive two major Android updates with security updates until 2027.
