Rivals to consider

Display & Design

The Redmi Note 15 Pro features a spacious 6.83-inch AMOLED panel with a 1220×2772 resolution, delivering crisp 1.5K visuals with an impressive 86.8% screen-to-body ratio1. The display reaches up to 3,200 nits peak brightness2, ensuring excellent outdoor visibility even under direct sunlight. The 120Hz refresh rate provides smooth scrolling and responsive touch interactions for gaming and daily use.

The device boasts IP68/IP69K certification, offering protection against submersion up to 1.5m for 30 minutes and high-pressure water jets1. At 211 grams, it’s heavier than its predecessor due to the larger battery, but the weight distribution feels balanced in hand. The dual nano-SIM setup maintains practicality for users needing multiple numbers.

Performance & Thermals

The MediaTek Dimensity 7400 Ultra SoC powers the device, an overclocked version of the Dimensity 7300 found in the Note 14 Pro. Built on a 4nm process, this chipset handles everyday tasks smoothly, from social media browsing to multitasking between apps. The processor delivers 7% improvements in both CPU and GPU performance compared to its predecessor, paired with a 5,200mm² vapor chamber for thermal management during extended gaming sessions.

The phone comes with either 8GB or 12GB of RAM paired with 256GB or 512GB of UFS 2.2 storage. While not the fastest storage standard available, it provides adequate read/write speeds for most users’ needs.

Camera Quality (Photos & Video)

The camera setup remains unchanged from the predecessor, featuring a 50MP main sensor with optical image stabilization and an 8MP ultrawide lens with a 112-degree field of view. The main camera uses a 1/1.95″ sensor size with 1.6µm pixels, capturing decent detail in good lighting conditions. The OIS helps reduce blur in low-light shots and provides steadier video recording.

The 20MP front camera handles selfies adequately, though it lacks the higher resolution found in some competitors. Video recording tops out at 4K 30fps on the main camera, with electronic stabilization helping to smooth out handheld footage.

Battery Life & Charging

The standout feature is the massive 7,000mAh battery, up from 5,500mAh in the Note 14 Pro. This substantial capacity should easily deliver all-day battery life even for heavy users, with many potentially seeing two days of moderate use. Charging speeds are set at 45W for the standard Note 15 Pro, which is slower than some competitors but still respectable for overnight charging.

The device supports 22.5W reverse wired charging, allowing it to function as a power bank for other devices — particularly useful given the large battery capacity.

Software & Updates

The phone runs Android 15 with Xiaomi’s HyperOS 2 interface1, representing the latest software from both Google and Xiaomi. HyperOS 2 brings a cleaner interface compared to older MIUI versions, with improved animations and better optimization for the large display.

Xiaomi hasn’t officially confirmed the update policy for this device yet, but based on recent Redmi Note models, users can expect at least two major Android updates and three years of security patches.

Price & Availability

• China pricing: Starts at CNY 1,999 (approximately ₹23,000) for the 12GB/256GB variant

• India pricing: Expected around ₹24,990 for the base variant (unconfirmed)

• Availability: Launched in China on August 21, 202534; India launch date not yet announced

The device is currently only confirmed for the Chinese market. According to tipsters, the Redmi Note 15 Pro series could launch in India in October5, though Xiaomi hasn’t made any official announcements regarding Indian availability.

Should You Upgrade?

From last year’s model: If you own the Redmi Note 14 Pro, the upgrade primarily brings a larger battery and slightly bigger display. Unless battery life is a major concern, you can comfortably skip this generation as the camera and overall performance improvements are minimal.

From a 2-year-old phone: Users with a Redmi Note 12 Pro or older will see substantial improvements across the board — the newer processor, massive battery, improved display brightness, and IP69K certification make this a worthwhile upgrade for enhanced daily use experience.

For budget-conscious buyers: At the expected ₹24,990 price point, the device offers solid value, especially for users prioritizing battery life. However, waiting for official India pricing and comparing with festive season deals on the Note 14 Pro might yield better value.

FAQs

Does Redmi Note 15 Pro include a charger in the box? This hasn’t been confirmed for the Indian market yet. The China variant’s box contents may differ from what arrives in India.

Is there an IP rating for water resistance? Yes, both Note 15 Pro models feature IP68/IP69K water and dust resistance4, offering protection against submersion and high-pressure water jets.

Does it support eSIM or microSD expansion? The device uses dual nano-SIM slots. MicroSD expansion and eSIM support haven’t been confirmed for this model.

When will it launch in India? No official announcement yet. Rumors suggest an October 2025 launch for India5, but this remains unconfirmed by Xiaomi.

Pros

• Exceptional 7,000mAh battery capacity for multi-day usage

• Bright 3,200 nits AMOLED display with smooth 120Hz refresh rate

• IP69K certification provides superior water and dust protection

Cons

• Camera setup unchanged from predecessor despite price increase

• 45W charging speed feels slow for such a large battery

• No official India launch date or pricing confirmation yet

Verdict

The Redmi Note 15 Pro impresses with its massive battery upgrade and enhanced durability, making it an attractive option for users who prioritize all-day reliability over cutting-edge performance. While the unchanged camera system and modest processor upgrade might disappoint spec enthusiasts, the combination of a large, bright display and exceptional battery life addresses real-world usage needs effectively. For Indian consumers, the lack of official launch confirmation means playing the waiting game, but if priced competitively around ₹25,000, this could be a solid mid-range choice for battery-conscious buyers. However, those seeking camera improvements or flagship-level performance should look elsewhere or wait for the Pro+ variant.
