Xiaomi Redmi Note 15 5G review: specs, battery & used prices

Summary

The Xiaomi Redmi Note 15 5G is Xiaomi's 2025 mid-range workhorse: a Snapdragon 6 Gen 3, a 6.77-inch 120 Hz OLED, and a 5,520 mAh battery with an IP66 rating. The 6/128 GB tier lists at $199 new, while the used record shows the 12/256 GB tier around $298 across two sales — an odd premium over the base new price that reflects trim shortages rather than depreciation. Five OS-update years are declared.

Display and design

The 6.77-inch OLED refreshes at 120 Hz with 800 nits of peak brightness; screen quality is 61/100 — an OLED with a 120 Hz refresh at a $199 opening price is the headline of the model. The 178 g body scores 93/100 on compactness, and IP66 covers heavy rain and water jets, short of submersion.

Performance

The Snapdragon 6 Gen 3 posts everyday responsiveness 67/100 and gaming 15/100 — a modern efficiency platform: daily operation is smooth, and gaming beyond casual titles is not the brief.

Camera

The camera pairs a 108 MP main sensor with optical stabilization and an ultrawide, recording 4K30; camera score 37/100. The high main-sensor resolution and OIS give it daylight detail above its bracket; low light and the secondary lens are where the price shows.

Battery and charging

Battery life scores 50/100 on the 5,520 mAh cell, while 45 W charging scores 26/100 — above the bracket's 18-33 W norm. The battery-and-charging pair is coherent: a day of use and a quick partial refill.

Verdict

At $199 new, the Redmi Note 15 5G buys a 120 Hz OLED, IP66, OIS, and a five-year update window — a strong mid-2020s baseline. The Xiaomi Redmi Note 12 Pro is the previous-generation alternative, and the Xiaomi Redmi Note 13 is the 2023 model it succeeds in the used market.
