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

Summary

The Xiaomi Redmi Note 15 SE 5G is a 2026 mid-ranger on the Snapdragon 6 Gen 3, with a 6.77-inch 120 Hz OLED rated at 800 nits, a 5800 mAh battery with 45 W charging, and an IP66 body at 178 grams. Our catalog scores it 93 on compactness, with the 6/128 GB trim listed new near $215. A single 50-megapixel main camera anchors the rear. The Xiaomi Redmi Note 15 5G is the line sibling, and 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 peak, and the deep contrast of the panel is the visual selling point at this price. The IP66 body at 178 grams is light for its screen size, and our compactness score of 93 marks one of the easiest large phones to carry in the catalog. The design stays restrained with a clean rear and a modest camera island.

Performance

The Snapdragon 6 Gen 3 earns an everyday axis of 58 and a gaming axis of 15 in our model: everyday apps, media and navigation run smoothly on the 120 Hz panel, while 3D gaming stays in the light-title zone. Tracked trims carry 6 to 8 GB of RAM for orderly multitasking. Our records do not list a software window for this model.

Camera

A single 50-megapixel main sensor anchors the rear without ultrawide or telephoto partners, and our records track no optical stabilization or video ceiling for this model. The camera axis of 10 is bottom-tier: daylight documentation shots are the working mode, and the single-lens layout leaves no versatility. The OLED screen, not the camera, is where the budget went.

Battery and charging

The 5800 mAh battery scores 56 on our battery axis, a comfortable full day and often more at moderate use, and the 45 W charger scores 26 in our records, restoring the cell in about an hour and a half. The pairing of a light 178-gram body with this capacity is the model's engineering argument. Wireless charging is absent at this tier.

Verdict

The Redmi Note 15 SE 5G is a light, sealed, OLED-equipped mid-ranger at $215 new: a 93 compactness score, an IP66 body and a 5800 mAh cell in 178 grams. The bottom-tier single camera and the undocumented update window are the explicit trade. For buyers who prioritize screen, weight and sealing over optics, it is a rational budget pick, with the Redmi Note 15 5G as the line sibling.
