Xiaomi has officially launched the Redmi Note 15 Pro+ 5G in China, featuring a 7000 mAh battery and a 120 Hz AMOLED display. The device, introduced on 21 August 2025, signals Xiaomi’s effort to push its mid-range Note series into the premium performance category, blending battery endurance, processing speed, and design finesse.
Redmi Note 15 Pro+ 5G Design and Display: 120 Hz AMOLED for Flagship-Level Visuals
The Redmi Note 15 Pro+ 5G sports a 6.83-inch AMOLED panel with a 120 Hz refresh rate and 1.5K resolution (1280 Ă— 2772 pixels). Xiaomi said during the launch that the adaptive refresh rate technology dynamically adjusts between 60 Hz and 120 Hz depending on content, helping to conserve power during light use.
According to Gadgets 360, the screen achieves up to 1800 nits peak brightness, ensuring visibility even under direct sunlight. The display supports HDR10+ and Dolby Vision, features that bring it closer to flagship phones priced above â‚ą40,000.
Performance and Hardware: Snapdragon 7s Gen 4 and Advanced Cooling
Under the hood, the smartphone is powered by Qualcomm’s Snapdragon 7s Gen 4 processor built on a 4-nanometre fabrication process, which improves efficiency and reduces thermal output. It is paired with up to 12 GB LPDDR5 RAM and 256 GB of UFS 4.0 storage, offering faster data access and app loading times.
In benchmark tests reported by India Today Tech, the device scored above 750,000 on AnTuTu, placing it comfortably among the top-performing midrange phones of 2025. Xiaomi’s custom vapor cooling chamber ensures consistent gaming performance during extended sessions.
“The combination of Snapdragon 7s Gen 4 and Xiaomi’s MIUI 15 optimization represents a balance of power and efficiency rarely seen in this segment,” said Ankit Malhotra, Senior Analyst at Counterpoint Research.
Battery Life: 7000 mAh Capacity with 90 W Fast Charging
The 7000 mAh battery is the phone’s standout feature, making it one of the largest batteries in its category. Xiaomi claims the device can provide up to two days of mixed-use runtime, including streaming, photography, and gaming.
It supports 90 W turbo charging, capable of reaching 50 percent charge in about 15 minutes and full charge in approximately 38 minutes, according to company figures. The charger is included in the box — a decision contrasting with some rivals that now sell chargers separately.
Battery longevity is aided by Smart Charge 4.0, an algorithm that adapts to usage patterns to slow charging overnight, reducing long-term wear on the lithium-polymer cells.
Redmi Note 15 Pro+ 5G Camera System
The Redmi Note 15 Pro+ 5G includes a 108 MP main camera, an 8 MP ultra-wide sensor, and a 2 MP macro lens. The primary sensor uses Samsung’s ISOCELL HM6 technology for enhanced low-light performance and faster autofocus.
Video recording supports up to 4K at 60 fps, with optical image stabilization (OIS). On the front, a 32 MP selfie camera housed in a punch-hole cutout caters to vloggers and social media users.
Early reviewers on Chinese tech platforms noted improved image sharpness and colour balance compared to the Note 14 Pro+, though low-light noise remains noticeable in extreme conditions.
Durability and Build: IP68 Protection and Refined Design
For the first time in the Note series, Xiaomi has provided IP68 certification for dust and water resistance, bringing the device closer to flagship standards. The phone uses a frosted glass back panel with an aluminium frame and Corning Gorilla Glass Victus protection on the front.
The design has been refined with thinner bezels and a flatter edge aesthetic, similar to Xiaomi’s flagship 14 series.

According to Canalys, mid-range phones with larger batteries and high-refresh displays have seen a 24 percent year-on-year sales increase in India, driven by users seeking long-lasting performance in regions with limited charging access.
Xiaomi’s Strategy: Capturing the Midrange Market
Xiaomi’s Note series remains a key revenue driver for the company, especially in India and Southeast Asia. With the Redmi Note 15 Pro+ 5G, the brand is doubling down on features that resonate with power users — large batteries, high-refresh displays, and efficient processors.
“The Note series bridges affordability and premium experience, and Xiaomi’s consistent upgrades show how critical this category is to its global market share,” said Navkendar Singh, Associate Vice President at IDC India.
Xiaomi is also expected to launch localized variants for the Indian market, potentially including different charging speeds and camera sensors to meet pricing constraints.
Environmental Initiatives and Sustainability
In line with its global environmental goals, Xiaomi has pledged to reduce packaging plastic by 60 percent by 2026. The company also operates a battery recycling program in select markets, encouraging users to trade in old devices for store credits.
The Redmi Note 15 Pro+ 5G uses energy-efficient display technology that lowers power draw by up to 14 percent compared to last year’s model, according to Xiaomi’s internal data.
5G and Connectivity: Preparing for Next-Gen Networks
The smartphone supports dual 5G standby, Wi-Fi 6E, and Bluetooth 5.3, ensuring compatibility with next-generation networks. The inclusion of 13 5G bands makes it suitable for international use, including in India’s major telecom circles.
Industry observers believe such support is crucial as India’s 5G network rollout expands beyond metro cities. “Smartphones like the Redmi Note 15 Pro+ 5G are helping accelerate mainstream 5G adoption,” said Tarun Pathak of Counterpoint Research.
Launch Offers and Early Buyer Discounts
In China, Xiaomi has introduced early-buyer discounts and bundle offers that include discounted accessories such as Redmi Buds 6 Pro and wireless chargers. However, the company has not confirmed Indian launch offers yet.
Experts expect limited-time promotions with bank cashback and exchange bonuses once the model debuts in India, mirroring Xiaomi’s strategy from previous Note launches.
Future Outlook: What It Means for 2026 Smartphones
The Redmi Note 15 Pro+ 5G exemplifies a broader industry shift toward battery endurance and display quality as differentiators in the midrange segment. Analysts predict more brands will follow Xiaomi’s model, combining large batteries, fast charging, and adaptive refresh displays in their 2026 releases.
