Frequently asked

When will the POCO M8 Pro 5G stop getting security updates?

POCO extended its support policy with this generation, giving the M8 Pro 5G four Android upgrades and six years of security patches from its January 2026 launch, so it should be maintained until roughly January 2032. It ships on Android 15 with HyperOS 2 and can climb toward Android 19 over time. That kind of runway used to be reserved for flagships, which makes it a standout for anyone keeping a budget phone for many years.

Is the POCO M8 Pro 5G worth buying in 2026?

For under $300 it is one of the best-supported and best-equipped budget phones you can buy. The OIS main camera, 100W charging, IP69K sealing and six-year patch guarantee mean the roughly $299 price works out to about $4.15 a month of safe use across its life. It is not a gaming powerhouse and the secondary cameras are basic, but as a dependable long-life daily driver it is hard to beat.

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.
