Redmi Note 15 5G is a mid-range 5G smartphone in the hugely popular Note series, built to offer a flagship‑like display and battery at an affordable price. It sits just below the Redmi Note 15 Pro models but still packs a 120 Hz AMOLED screen, Snapdragon 6 Gen 3, and a big battery, making it a balanced all-rounder for gaming, multimedia, and everyday use across markets like India, Europe, and Southeast Asia. The Redmi Note 15 is launching on 6 January.

OVERVIEW: REDMI NOTE 15 5G
Design and Display
Redmi Note 15 follows Xiaomi’s new flat-edged design language, with a glass front, plastic frame, and a clean rectangular camera island on the back. The phone measures roughly 164 x 75 x 7.4 mm and weighs about 178 g, so it feels slim and fairly light in hand despite its big battery. The body is rated IP66 for dust tightness and high-pressure water resistance, and Xiaomi also advertises drop resistance up to around 1.7 m in some global specs, which adds confidence if the device slips from a pocket or desk. Color options globally typically include Black, Glacier Blue, and a lighter Mist/Purple shade, each with a satin matte finish that hides fingerprints more effectively than glossy backs.
On the front, the Redmi Note 15 uses a 6.77-inch AMOLED panel with a 1080 x 2392 resolution and around 388 pixels per inch, so content looks sharp without pushing power consumption as high as QHD. The screen supports a 120 Hz refresh rate for smooth scrolling and animations, plus high-frequency PWM dimming and a peak brightness in the 3,000+ nits range, which keeps it readable outdoors and allows HDR video playback on platforms like YouTube. Xiaomi protects the display with scratch/drop‑resistant glass (Dragon Crystal or a Mohs level 5 type layer, depending on region). The bezels are slim, and the punch‑hole selfie camera sits at the top center, giving roughly 89–90% screen-to-body ratio.
Cameras
Photography is handled by a dual rear camera system focused on a strong main sensor plus a useful ultrawide. The main camera is a 108 MP wide lens with an f/1.7 aperture, around a 1/1.67″ sensor size, phase‑detect autofocus, and optical image stabilization. This combination lets the phone capture detailed daylight shots and brighter low‑light images with less blur, while 9 in 1 pixel binning outputs 12 MP photos for regular use. The secondary camera is an 8 MP ultrawide with a 16 mm equivalent focal length that is handy for landscapes, architecture, and group photos. There is no separate telephoto, but the high‑resolution main sensor supports usable 2x–3x in‑sensor zoom.
The rear camera shoots video in 4K at 30 fps, and you can switch to 1080p at 30 fps if you want. Plus, gyro-EIS keeps your footage steady and smooth. Up front, the Redmi Note 15 packs a 20 MP selfie camera with an f/2.2 lens. It records 1080p video-perfect for social media, video calls, or even a bit of vlogging.
Performance
Inside, Redmi Note 15 is powered by Qualcomm’s Snapdragon 6 Gen 3, a 4 nm mid‑range 5G SoC with a CPU cluster of four Cortex-A78 performance cores at up to 2.4 GHz and four Cortex-A55 efficiency cores for lighter tasks. This chip is paired with an Adreno 710 GPU, which is strong enough for popular titles like BGMI, Free Fire, and Call of Duty Mobile at medium-to-high graphics and a stable frame rate. RAM and storage options vary by market but commonly include 6 GB + 128 GB, 8 GB + 256 GB, and up to 12 GB + 512 GB, using UFS 2.2 storage and offering a hybrid microSD slot for expansion if needed.
Redmi Note 15 runs Android 15 with Xiaomi’s HyperOS 2 on top. Xiaomi has committed to multiple years of OS and security updates on its newer devices, and the Note 15 benefits from the new HyperOS design language, smoother animations, and tighter integration with Xiaomi ecosystem products like tablets, TVs, and wearables. Features like Game Turbo, memory extension (virtual RAM), and advanced privacy controls are included.
Battery and Charging
Battery life is one of Redmi Note 15 strongest points. The phone uses a silicon‑carbon or Li-Ion cell of around 5,500-5,800 mAh capacity, depending on whether you look at regional versions or typical/nominal figures. In daily use, this translates into at least a full day and often closer to a day and a half of mixed browsing, social apps, streaming, and some gaming. Charging is rated at 45 W wired, which can take the phone from empty to about 50% in half an hour and to full in roughly an hour. Some specs also mention support for 18-22.5 W reverse wired charging, meaning you can top up accessories like earbuds or another phone using a cable.

Connectivity
As a 5G device, Redmi Note 15 supports a wide range of sub-6 GHz 5G bands across regions, along with the usual 4G LTE, 3G, and 2G support. There is dual-SIM capability (nano + nano), Wi-Fi 5 or Wi-Fi 6 (depending on the listing), Bluetooth 5.x, NFC in many markets, GPS/GLONASS/Galileo/BeiDou positioning, and an IR blaster on the top edge to control TVs and other appliances. USB-C 2.0 is used for charging and data, and OTG support is present.
For audio, the phone includes stereo speakers with Dolby Atmos support and high-resolution audio certification. Many recent Redmi mid-rangers have dropped the 3.5 mm headphone jack; whether your region gets the jack or not will depend on the specific global vs. China variant, so it is worth checking the local product page. Biometric security is handled by an under-display optical fingerprint sensor, backed by AI face unlock.
