The latest specs rumor about the Xiaomi Mi 12 has concentrated on its memory type. Unsurprisingly, it's expected that the Mi 12 will sport the brand-new LPDDR5X RAM that has just been announced by JEDEC. This latest improvement offers up to over 33% faster data transfer rates than the LPDDR5 RAM found in phones like the Xiaomi Mi 11.
