Xiaomi Redmi K90 Pro Max
By Muhammad Tahir · Updated July 2026 · how we review
The Redmi K90 Pro Max squeezes Snapdragon 8 Elite Gen 5 and a 7,560mAh battery into a mid-range price, but its update timeline is Xiaomi's typical estimate, not a written guarantee.
Is the Redmi K90 Pro Max still supported?
Our estimateSupported until October 2031 · Buy-by October 2029
✓ Yes — the Redmi K90 Pro Max is expected to be supported until October 2031, roughly 5.1 more years.
Apple doesn't publish an end date, but iPhones have a consistent ~6-year update track record — on that basis the Redmi K90 Pro Max should be supported until around October 2031. Buying it today still gets you about 5.1 years of safe use, and Apple's written legal minimum is 5 years (verified July 2026).

Frequently asked questions
How long will the Redmi K90 Pro Max receive updates?
Xiaomi hasn't published a written promise for this China-only model, so PhoneLifespan estimates 4 years of OS upgrades and 6 years of security patches based on Redmi K-series track record, putting realistic end-of-support around October 2031.
Can I use the Redmi K90 Pro Max in the US?
It's not officially sold in the US; you'd need to import a Chinese unit, manually add Google apps, and accept no US carrier certification or warranty.
What makes the K90 Pro Max stand out?
It pairs the same Snapdragon 8 Elite Gen 5 found in Xiaomi's true flagships with a 7,560mAh battery, Bose-tuned speakers, and a 5x periscope telephoto, all at roughly half the price of the Xiaomi 17 Pro Max.
Redmi K90 Pro Max vs Poco F8 Ultra -- which is the better buy?
They're closely related: the Poco F8 Ultra is effectively the global-market twin sharing the Snapdragon 8 Elite Gen 5 and Bose audio tuning, but it has genuine global retail availability and a confirmed 4-year OS / 6-year security promise, while the K90 Pro Max remains China-only with an estimated update timeline.
