Frequently asked
How long will the Redmi K90 get updates?
There's no official Xiaomi document for this China-only model, so PhoneLifespan estimates 4 years of OS upgrades and 6 years of security patches based on Redmi's recent track record, putting realistic end-of-support around October 2031.
What's the difference between the Redmi K90 and K90 Pro Max?
The K90 uses the older Snapdragon 8 Elite (not Gen 5), an 8MP ultra-wide instead of 50MP, and a smaller 7,100mAh battery versus the Pro Max's 7,560mAh -- at a notably lower CNY 2,599 starting price.
When will the Redmi Note 15 Pro+ 5G stop getting security updates?
The Redmi Note 15 series carries a four OS upgrade and six-year security commitment, so from the January 2026 global launch the Pro+ should be patched until about January 2032. It ships on Android 15 with HyperOS 2 but is set to move to HyperOS 3 and Android 16 quickly, and can reach roughly Android 19 over its life. That is a notable upgrade over the three-to-four-year windows earlier Note Pro+ phones received.
Is the Redmi Note 15 Pro+ 5G worth buying in 2026?
It is one of the strongest mid-range all-rounders if you value a headline camera and durability. The 200MP sensor, 100W charging and IP69K sealing feel a class above the price, and with six years of patches the roughly $449 cost breaks down to about $6.25 a month of safe use. The caveats are the basic secondary cameras and a chipset tuned for efficiency rather than top-tier gaming.
