NeoTeo's verdict
Which of the two is the better buy
The Xiaomi Redmi K90 Max is the pick for anyone seeking a current, powerful phone: its Dimensity 9500, 16 GB of RAM, and 3500-nit AMOLED display put it well ahead of the Redmi 9. The major tradeoff is that the K90 Max lacks Google services, which the Redmi 9 has.
The K90 Max’s screen measures 6.83″ versus 6.53″, with 1280 × 2772 px versus 720 × 1600 px. Its main camera also leads, with 50 MP and a 1/1.55″ sensor versus 13 MP and 1/3.06″; it records video up to 8K, while the Redmi 9 tops out at 1080p.
The K90 Max pairs an 8550 mAh battery with 100 W charging, against 5000 mAh and 10 W. It also adds 5G and Wi-Fi 7. The Redmi 9 keeps practical advantages: Google services, expandable storage, and a 3.5 mm headphone jack. It makes sense for someone who needs those features, not for someone seeking stronger performance, a better display, or more capable cameras.
