It is not clear when the Redmi 11T Pro can be upgraded to the Pempie, as no specific timetable has been officially announced. However, as Pempie is a new operating system and may require more testing and adaptation to make it fully compatible with the Redmi 11T Pro's hardware and software environment, we may have to wait a while before we see the upgrade roll out. We can follow official announcements and updates for the latest information and possible timelines.
