POCO X3 Pro specifications
Up until now, very little information was available regarding the POCO X3 Pro specifications. However, the recent tweet from leaker Mukul Sharma states that this phone will be equipped with a Snapdragon 860 chipset. The phone will feature an FHD+ display with a 120Hz refresh rate and a 5,200mAh battery. Of course, since this is a leak, it should be taken with a pinch of salt. The Snapdragon 860 is said to be an improved variant of the Snapdragon 855 with faster clock speeds. The 5,200mAh battery should support fast charging, but more details aren’t known right now.

Since the POCO F3 is expected to be a rebranded Redmi K40, it should have a 6.67-inch FHD+ display with a 120Hz refresh rate, the Snapdragon 870 chipset with 5G connectivity, up to 12GB RAM and 256GB storage, and a 4,520mAh battery with 33W fast charging support. The Redmi K40 also comes with a triple rear camera setup with a primary 48-megapixel sensor, an 8-megapixel ultra-wide unit, and a 5-megapixel macro sensor. It gets stereo speakers, Dolby Atmos, IP53 rating, and runs Android 11 based MIUI 12 OS.
