Winner
Xiaomi Redmi K90 Pro Max
Lifespan decides this one: the Redmi K90 Pro Max is supported until Oct 2031 at $8.11 per month of safe use, while the Nova 15 Pro runs out in Dec 2028 ($17.61/month). On a which-lasts-longer question, that's not a tie — it's the whole answer.
Value Score: Nova 15 Pro 67 · Redmi K90 Pro Max 82 — methodology
Who should pick which
Beyond the scores — our take on each phone and the buyer it actually suits.
A slim, camera-and-battery-focused Huawei mid-premium phone with a bright 120Hz screen and 100W charging, but it's China-first, runs HarmonyOS without Google, and support is only estimated.
Pick it if
- ✓ Huawei-ecosystem users who want flagship-style cameras and battery without flagship prices
- ✓ Buyers who prioritise a bright screen, fast charging and a real zoom lens
- ✓ People comfortable living without Google services
Skip it if
- ✗ You need Google apps, wireless charging or guaranteed long-term updates
- ✗ You want easy global availability and local warranty support
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.
Pick it if
- ✓ Value-focused buyers who want flagship silicon on a budget
- ✓ Battery-life-obsessed users
Skip it if
- ✗ You need a guaranteed, documented update policy
- ✗ You require an official warranty in your country

Frequently asked
When does the Huawei Nova 15 Pro stop getting updates?
Huawei does not publish a fixed update schedule. As a mid-premium Nova device we estimate around 2 HarmonyOS updates and roughly 3 years of security patches from its December 2025 launch, so into about 2028, typically a bit shorter than Huawei's top Mate flagships and well short of the 6 to 7 years some rivals now promise.
Does the Nova 15 Pro work with Google apps outside China?
No. It ships with HarmonyOS 6 and Huawei Mobile Services and has no Google Play Store. It is also sold primarily in China, so buying it elsewhere means importing, dealing with region-specific software and losing easy access to Google apps, fine for Huawei fans but frustrating for anyone tied to Google.
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.
