Design & build

The Redmi Note 15 line looks and feels slim. The Note 15 5G has a curved front and back, a thin metal-reinforced mid-frame, and high-durability glass on the screen.

It measures about 7.35 mm thick and weighs 178 g. The phone comes in Mist Purple, Black and Glacier Blue and has IP66 dust/water resistance.

The standard Redmi Note 15 is a bit thicker and heavier than the 5G version but offers a larger 6,000 mAh battery with the same 6.77-inch AMOLED display. It focuses on better battery life, while the 5G model is slimmer and lighter.

Display Specifications

The Redmi Note 15 features a 6.77-inch FHD+ AMOLED display with a 120 Hz refresh rate and 240 Hz touch sampling, delivering smooth visuals and responsive touch input.

High peak brightness ensures good outdoor visibility, while HDR support and a wide color gamut enhance video quality.

Overall, the display is well-suited for everyday use, media consumption, and casual to moderate gaming, though it is not designed for ultra-high refresh competitive play.

Performance

Powered by the Snapdragon 6 Gen 3, the device uses a 4 nm mid-range chipset with Cortex-A78 and A55 cores paired with an Adreno 710 GPU.

It delivers smooth everyday performance and good efficiency but falls short of flagship-level power. LPDDR4X RAM and UFS 2.2 storage ensure responsive daily use.

Casual and popular games run well at medium settings, while demanding titles need reduced graphics.

Thermals remain controlled, with only minor throttling during sustained heavy workloads, aligning with typical mid-range performance expectations.

Battery

The Redmi Note 15 lineup features large batteries ranging from about 5,520 mAh to 6,000 mAh, depending on the variant, paired with 45 W wired charging.

Battery life typically lasts a full day or more, with 7–9 hours of screen-on time under balanced use.

Charging is fast for the segment, reaching around 50% in 30 minutes and a full charge in just over an hour. Wireless charging is not supported, and heavy use or high refresh settings can reduce runtime.

Software, updates & connectivity overview

The phone ships with HyperOS 2 based on Android 15, offering a clean, customizable interface with strong privacy controls and AI-assisted features.

Xiaomi promises long-term support with up to four major Android updates and six years of security patches, with HyperOS 3 (Android 16) expected later. Connectivity is well-rounded, including dual 5G, Wi-Fi 5, Bluetooth 5.x, NFC (market dependent), and USB-C.

Extra features like an IR blaster, 3.5 mm headphone jack, microSD expansion, in-display fingerprint sensor, face unlock, and a full set of sensors add practical value for everyday use.

Pricing and Storage Options in India

The Redmi Note 15 5G in India is available in 8 GB + 128 GB and 8 GB + 256 GB variants, both using LPDDR4X RAM and UFS 2.2 storage with microSD expansion.

Priced under ₹25,000, it offers competitive value in the mid-range segment. Strong highlights include the 108 MP camera, AMOLED display, and large battery, making it a solid option in the ₹20k–₹25k bracket, though some rivals offer faster memory or larger batteries.
