Xiaomi Redmi Note 15 4G review: specs, battery & used prices

Summary

The Xiaomi Redmi Note 15 4G is a 2025 entry mid-ranger on the Helio G100, pairing a 108-megapixel main camera with a 6.77-inch 120 Hz OLED rated at 800 nits, a 6000 mAh battery and 33 W charging in an IP64 body at 184 grams. Our catalog scores it 89 on compactness and 60 on battery life, with three years of OS updates declared; everyday use sits at 36 and gaming at 6. Tracked listings start at about $199 for the 6/128 GB trim. The Xiaomi Redmi Note 15 5G is the network-upgraded sibling, while the Xiaomi Redmi 15 4G is the battery-first alternative.

Display and design

The 6.77-inch OLED refreshes at 120 Hz with an 800-nit rating, scoring 61 on our screen axis: OLED contrast at an entry price, though outdoor brightness is modest. The 184-gram IP64 body earns a compactness score of 89, unusually light for a phone carrying a 6000 mAh cell.

Performance

The Helio G100 posts an everyday axis of 36 and a gaming axis of 6 in our model: the platform covers communication, media and everyday apps at entry-mid expectations, with gaming beyond casual titles outside the brief. The three-year software window is a relative strength at the price.

Camera

Photography relies on a single 108-megapixel main camera; our records list no ultrawide or telephoto, and optical stabilization is absent. The camera axis of 22 marks daylight-snapshot capability with crop-zoom headroom from the resolution, and the usual entry-tier limits everywhere else.

Battery and charging

The 6000 mAh battery scores 60 on our battery axis, a comfortable full day and often more at moderate use, while 33 W charging earns a charging score of 15. At 184 grams, the endurance-to-weight ratio is the practical highlight of the hardware.

Verdict

At about $199 new for 6/128 GB, the Redmi Note 15 4G is an OLED-screen endurance value: a 6000 mAh cell and a large 120 Hz OLED in one of the lightest bodies in its class. Camera and performance scores frame the trade-offs. Used market data is sparse, so the new price is the reference.
