The “Note” series has always been the bread and butter for Xiaomi in India. But let’s be honest—lately, the competition from brands like Realme and Motorola has been brutal. The real truth is, Xiaomi needed a home run to start 2026, and the Xiaomi Redmi Note 15 5G is their answer.
Launched on January 6, 2026, with a starting price of ₹22,999, this phone isn’t just a minor spec bump. It is officially the slimmest and lightest Redmi Note ever made. But in a market where everyone is offering “flagship killers,” does a slim design and a 108MP camera justify the price hike? We spent a week with the Mist Purple variant to find out.

DESIGN & BUILD (Deep Dive)
Don’t waste your money if you are looking for a rugged, bulky tank. The Redmi Note 15 5G is built for the fashion-forward user. At just 7.35mm thin, it feels incredibly sleek. Xiaomi has finally brought the 3D Curved Display to the base “Note” model, which was previously reserved for the ‘Pro’ and ‘Pro+’ variants.
The back panel is where the magic happens. The Mist Purple version we tested features a “wave-like” pattern that shifts under light. It’s a head-turner, but it’s also practical. The curved edges mean the phone doesn’t dig into your palms. Surprisingly, despite the thinness, they’ve managed to keep the IR Blaster at the top—a classic Xiaomi touch that many of us still love.
DISPLAY & VISUALS
The screen is arguably the biggest upgrade this year. We are looking at a 6.77-inch Curved AMOLED panel.
- Outdoor Visibility: In our testing under the harsh 12:00 PM Delhi sun, the 3200 nits peak brightness was a lifesaver. You won’t be squinting to read a WhatsApp message here.
- Color Accuracy: It supports 100% DCI-P3 color gamut. Movies on Netflix look vibrant, with deep blacks that only an AMOLED can provide.
- The “Wet” Factor: Xiaomi introduced Wet Touch 2.0. We tested this by splashing some water on the screen and trying to type. While it’s not perfect, it’s significantly better than previous years where a single drop of rain would make the ghost-touches go wild.
PERFORMANCE & GAMING/USAGE
Under the hood, we have the Snapdragon 6 Gen 3. Now, let’s talk real numbers. In our AnTuTu v10 test, it scored around 626,000.
- Daily Tasks: Switching between Instagram, Slack, and Chrome is buttery smooth. HyperOS 2 feels much lighter than the old MIUI days.
- Gaming: We played BGMI and Genshin Impact. In BGMI, you can easily hit a stable 60 FPS on “Smooth + Extreme” settings. However, after about 40 minutes of gaming, the area near the camera module does get warm (around 41°C). It’s not “hot,” but you’ll feel it.
- Longevity: Xiaomi is promising 4 years of OS updates and 6 years of security patches. This is a massive win for someone who doesn’t want to change their phone every two years.
CAMERA / OPTICS
The star of the show is the 108MP Samsung HM9 sensor with OIS. This is the first time this specific sensor is appearing in this segment.
- Daylight: The details are crisp. If you zoom into a photo of a building, you can actually read the signs far away.
- Low Light: The OIS (Optical Image Stabilization) does its job. Night mode takes about 2 seconds to process, but the results are clean with minimal noise.
- The “Weak” Link: The 8MP ultra-wide is just… okay. It’s useful for landscape shots, but the color temperature is slightly different from the main 108MP sensor.
BATTERY & ENDURANCE
Xiaomi used an EV-grade Silicon-Carbon battery this time. This tech allows them to cram a 5,520mAh capacity into that tiny 7.35mm body.
- The 0-100% Test: Using the inbox 45W charger, the phone went from 0 to 50% in exactly 28 minutes. A full charge took about 68 minutes.
- Real World Usage: On a heavy day with 5G enabled, 2 hours of YouTube, and 1 hour of gaming, we still ended the day with 15% battery left. Most users will easily get 1.5 days out of this.

THE COMPETITION (Auto-Selected Rivals)
Redmi Note 15 5G vs Realme P4 5G vs Samsung Galaxy M36 5G
| Feature | Redmi Note 15 5G | Realme P4 5G | Samsung M36 5G |
| Price | ₹22,999 | ₹17,999 | ₹18,999 |
| Display | 3200 nits Curved AMOLED | 2000 nits AMOLED | 1000 nits Super AMOLED |
| Chipset | Snapdragon 6 Gen 3 | Dimensity 7050 | Exynos 1380 |
| Camera | 108MP (OIS) | 50MP | 50MP (OIS) |
The Verdict on Rivals:
The Realme P4 is cheaper, but it feels like a toy compared to the premium build of the Redmi Note 15. The Samsung M36 has better software (One UI), but the charging speed (25W) is painfully slow in 2026. The Winner is the Redmi Note 15 5G because it offers the best “premium feel” and display in this bracket.
FINAL VERDICT
Buy it if:
- You want the best-looking phone under ₹25k. The slim design is unbeatable.
- You consume a lot of content. The 3200 nits curved display is a treat for Netflix.
- You want a phone that lasts. 6 years of security updates is industry-leading at this price.
Skip it if:
- You are a hardcore competitive gamer. Look at the iQOO Z-series instead for raw power.
- You hate curved screens. They look great but can be prone to accidental touches.
- You want the fastest charging. 45W is good, but competitors offer 80W.
