About the Xiaomi Redmi Note 15
The Redmi Note 15 is the entry point to Xiaomi's biggest-selling family, and it plays that role sensibly rather than chasing headline specs. You get a 6.77-inch AMOLED panel with a 120Hz refresh rate and a peak brightness figure that helps in bright sunlight, a Snapdragon 6 Gen 3 chip that handles everyday apps and light gaming without drama, and a 5,520mAh battery paired with 45W charging, which is quick for this end of the market. The 108MP main camera is stabilised and produces detailed daylight shots, though the 8MP ultrawide alongside it is basic and there is no telephoto lens. Two things set it apart from rivals: it still takes a microSD card, so cheap storage expansion is on the table, and it has stereo speakers with Dolby Atmos. The trade-off for sitting at the entry point of the range is IP66 splash and dust protection rather than the full immersion rating the Pro models carry. It is a dependable, unflashy phone rather than an exciting one.

Frequently asked questions
Is the Redmi Note 15 worth buying?
The Redmi Note 15 is worth buying if you want a large AMOLED screen, solid battery life and expandable storage without paying mid-range money. Its Snapdragon 6 Gen 3 chip is built for everyday use rather than demanding games. If you want a sharper 1.5K screen, a 200MP camera or full waterproofing, the Redmi Note 15 Pro is the better fit.
Does the Redmi Note 15 have expandable storage?
Yes, the Redmi Note 15 supports microSDXC cards, using a shared slot alongside the SIM. That is increasingly rare and useful if you store a lot of photos or offline media. Internal options run from 128GB up to 512GB depending on the configuration.
How good is the Redmi Note 15 camera?
The Redmi Note 15 has a 108MP main camera with optical image stabilisation, which captures plenty of detail in good light and holds up reasonably after dark thanks to pixel binning. The 8MP ultrawide is a step down in quality, and there is no zoom lens. The 20MP front camera is fine for video calls and selfies.
Is the Redmi Note 15 waterproof?
The Redmi Note 15 has an IP66 rating, which means it is dust tight and protected against powerful water jets, so rain and spills are not a problem. It is not rated for immersion, unlike the Redmi Note 15 Pro and Pro+ which carry IP68 and IP69K ratings. Treat it as splash resistant rather than waterproof.
How does the Redmi Note 15 compare to the Redmi Note 15 Pro?
The Pro moves up to a 6.83-inch 1.5K OLED panel, a MediaTek Dimensity 7400 Ultra chip, a 200MP main camera and a much larger 6,580mAh battery, plus full IP68/IP69K water resistance. The standard Redmi Note 15 is lighter at 178g against 210g and keeps microSD expansion, which the Pro drops. Choose the Pro for the camera and battery, or the standard model if size, weight and expandable storage matter more.
Does the Redmi Note 15 have a headphone jack?
No, the Redmi Note 15 does not have a 3.5mm headphone jack, so you will need USB-C or wireless headphones. It does have stereo speakers with Dolby Atmos support, which is a genuine upgrade over the single speakers common on entry-level phones. Bluetooth headphones remain the simplest option for private listening.

Based on main-sensor size (1-inch / 1/1.3" beats 1/2.0"), telephoto reach (periscope > 5x > 3x optical), image processing tier (Apple Pro, Pixel Pro, Galaxy Ultra, Honor Magic Pro, Xiaomi Ultra), pro video features (ProRes, Apple Log, Dolby Vision), camera-partnership branding (Leica, Hasselblad, Zeiss) and OIS. Older flagships are de-rated since image processing pipelines have advanced significantly each generation. Megapixel count is deliberately downweighted — it correlates poorly with real-world camera quality. Where DXOMARK has lab-tested the phone, its measured score replaces this estimate.

Based on battery capacity (mAh) adjusted for platform efficiency calibrated against NotebookCheck, Tom's Guide, GSMArena and CNET reviewer tests. Apple A-series gets +45% (iOS process freezing + LTPO 1Hz + tuned panels make iPhone Pro Max outlast many 6500+ mAh Android phones in measured tests). Top Snapdragon / Dimensity flagships get +15%, budget chipsets are penalised −15% to −25% to reflect less efficient displays and looser background limits. Charging speed is excluded — see the separate Fast charging tag for that.
