Real-World Performance & First Impressions
Display & Design
The Note 15 sports a 6.77-inch OLED display that offers 120Hz refresh rate, 3,200 nits peak brightness, and Full HD+ resolution. The phone gets an in-display fingerprint scanner.1 This represents a major upgrade from previous generations, with the OLED panel bringing deeper blacks and more vibrant colors. The 3,200 nits peak brightness ensures excellent outdoor visibility even in direct sunlight. The in-display fingerprint sensor modernizes the design compared to side-mounted alternatives.
Performance & Thermals
It is equipped with a Snapdragon 6 Gen 3 SoC and is available in 6 GB/128 GB, 8 GB/128 GB, 8 GB/256 GB, and 12 GB/256 GB variants. It gets UFS 2.2 storage and LPDDR4X RAM.1 While the Snapdragon 6 Gen 3 isn’t a flagship processor, it provides solid mid-range performance suitable for everyday tasks, social media, and moderate gaming. The UFS 2.2 storage ensures decent app loading times, though it’s not as fast as UFS 3.1 found in higher-end devices.
Camera Quality (Photos & Video)
At the back, the smartphone features a dual camera setup with a primary 50 MP Light Fusion 400 sensor with f/1.8 aperture and a 2 MP depth camera. For selfies and video calls, the device features an 8 MP camera.1 The 50MP main sensor should deliver good daylight photography with adequate detail. The dual-camera setup is modest compared to triple-camera competitors, but the Light Fusion 400 sensor promises improved low-light performance. Video recording capabilities haven’t been detailed yet but are expected to include 1080p recording at minimum.
Battery Life & Charging
The Redmi Note 15 packs a 5,800 mAh battery and supports 45W fast charging and 18W wired reverse charging.1 The substantial 5,800mAh battery should easily last a full day of heavy use or potentially two days with moderate usage. The 45W charging is competitive for this segment, likely achieving a full charge in approximately 60-70 minutes. The reverse charging feature adds versatility for emergency power sharing with other devices.
Software & Updates
The Note 15 runs Android-15 based HyperOS 2 out of the box.1 HyperOS 2 represents Xiaomi’s latest interface evolution, promising smoother animations and better optimization. While specific update commitments haven’t been announced for the Indian variant, Xiaomi typically provides 2-3 years of Android updates and 4 years of security patches for the Note series.
Price & Availability
• Starting price: ₹13,9992 for the base variant (expected)
• Availability: Its India launch can happen by October 2025. Meaning this phone may be available for Indian buyers in time for the festive season3
Should You Upgrade?
From last year’s model: If you own the Redmi Note 14, the upgrade brings meaningful improvements in display technology (OLED vs LCD), battery capacity, and brightness levels. However, unless you specifically need the OLED display or larger battery, you could skip this generation.
From a 2-year-old phone: Users with Redmi Note 13 or older devices will see substantial improvements across the board – better display, newer processor, improved cameras, and significantly larger battery. This makes for a worthwhile upgrade, especially considering the expected competitive pricing.
For budget-conscious buyers: At an expected ₹13,9992 starting price, the Redmi Note 15 offers excellent value with its OLED display and large battery. However, waiting for initial reviews and potential festive season offers in October could yield better deals.
