The Redmi 9 M2004J19G has surfaced again, this time it was the FCC that released certification data and along with it some salient details about the upcoming phone. It will launch with MIUI 11, if that was ever in question, which likely means Android 10 out of the box.
The phone will be powered by a 5,000mAh battery. Unfortunately, theres no info on the charger there was some speculation that it will be 10W, a downgrade from the 18W charger the previous model used.
This will be an LTE phone, its too early for the series to go 5G. It will also support 2.4GHz and 5GHz Wi-Fi with 802.11ac, aka Wi-Fi 5.
