Xiaomi's unofficial update policy gives short shrift to the Redmi, Redmi Note, and POCO C series
According to a report posted on Telegram in the Xiaomi & MIUI News channel, the unofficial Xiaomi update policy for Android and MIUI upgrades shows that some devices will receive a total of six major software updates while others will only get three. In the case of the Xiaomi Mi A series, these smartphones will apparently only receive two upgrades, but as they are currently part of the Android One program this means two major OS updates that come straight from Google itself.
As for smartphones directly serviced by Xiaomi, it appears that all Xiaomi-branded devices can expect four MIUI upgrades and two Android upgrades. So that’s all the Mi series, Mi Mix, Mi Max, Mi Note, and Mi T (9T, 10T, etc.) phones. Premium devices from both the Redmi and POCO ranges also get the 4 + 2 treatment, with the Redmi K series, POCO F lineup, and POCO X phones included in the more-supported end of this unofficial update policy.
Unsurprisingly, budget-level smartphones get a short shrift in comparison. Redmi Note and POCO M smartphone users can expect to receive three MIUI upgrades and just one Android update, while the outlook for owners of regular Redmi series devices (Redmi 8, Redmi 9, etc) and POCO C phones (POCO C3) is even bleaker with apparently only two MIUI upgrades and a single Android update.
