Xiaomi has now launched the Redmi Note 15 in its home market. Available for as little as CNY 999 (~$139), the Xiaomi Redmi Note 15 still features hardware like a 3,200-nit OLED display, a modern Qualcomm Snapdragon chipset and a 50 MP primary camera.

Xiaomi has released the Redmi Note 15 in China, about which it revealed no details beforehand unlike the Redmi Note 15 Pro and Redmi Note 15 Pro Plus. Nonetheless, the Redmi Note 15 contains quite a few changes from the Redmi Note 14 (curr. $279 on Amazon).

For example, this year's model has grown 2 mm taller to measure 164 x 75.42 x 73.5 mm while dropping from 190 g to 178 g. As a result, Xiaomi has found enough space to include a 6.77-inch OLED display, which outputs at 1080p, 120 Hz and with 3,200 nits peak brightness. On top of that, battery capacity has grown from 5,110 mAh to 5,800 mAh between generations, albeit while retaining 45 W wired charging.

Moreover, Xiaomi has swapped the Dimensity 7025 Ultra from last year's model for the newer and more powerful Qualcomm Snapdragon 6 Gen 3. According to our benchmarks, this change should deliver around 18% performance improvements alone. Xiaomi has also swapped camera sensors to the Light Hunter 400, which could well be somewhat of a downgrade from the Sony LYT-600 used in the Redmi Note 14.
Xiaomi has not commented on international availability yet. Based on recent leaks, the company will offer the handset outside its home market as the Redmi Note 15 5G, though. For reference, the Redmi Note 15 is available in Azure Blue, Midnight is Dark and Starlight White colour options at the following prices:

  • 6 GB RAM/128 GB storage - CNY 999 (~$139)
  • 8 GB RAM/128 GB storage - CNY 1,099 (~$153)
  • 8 GB RAM/256 GB storage - CNY 1,299 (~$181)
  • 12 GB RAM/256 GB storage - CNY 1,499 (~$209)
