DISPLAY AND DESIGN.

Redmi Note 15 4G boasts a sleek, modern design that perfectly blends a high-end look with tough durability. It’s impressively slim at about 7.9mm thick and weighs in at 183.7g, making it easy to handle even with its hefty internal battery.

With a crisp FHD+ resolution of 1080 x 2392 pixels and a super-smooth 120Hz refresh rate, it’s hard to beat. One of its standout features is the peak brightness of 3,200 nits, which, combined with 3840Hz PWM dimming, keeps the screen clear and easy to read even in bright sunlight, while also minimizing eye strain in darker settings.

PERFORMANCE AND SOFTWARE.

Redmi Note 15 4G is driven by the MediaTek Helio G100 Ultra, a 6nm chipset that’s all about delivering top-notch 4G performance. This processor boasts an octa-core setup, featuring two powerful Cortex-A76 cores that can hit speeds of up to 2.2 GHz, making it perfect for multitasking, scrolling through social media, and enjoying some casual gaming. To keep everything running smoothly, you can choose between 6GB or 8GB of LPDDR4X RAM, which can even be virtually expanded by an extra 8GB thanks to Xiaomi’s Memory Extension technology. When it comes to storage, you have the option of 128GB or 256GB of UFS 2.2 flash memory, plus a microSDXC slot for those who need extra space for their media collections. On the software front, the phone launches with Android 15, featuring Xiaomi’s latest HyperOS 2 interface. This version is crafted for seamless connectivity across devices and comes with deep integration of Google Gemini AI, offering handy tools like AI-assisted image editing, smart search, and real-time translation. Xiaomi is also promising a “48-month like-new software experience,” which means the system will be optimized over time to keep things running smoothly as the phone ages. Plus, it’s set to receive up to four major Android OS upgrades, ensuring it stays up-to-date with new apps and security standards all the way through 2029.

CAMERA SYSTEM.

Redmi Note 15 4G boasts an impressive 108MP primary camera, powered by the Samsung ISOCELL HM9 sensor. This sizable $1/1.67$-inch sensor comes with an $f/1.7$ aperture and employs 9-in-1 pixel binning technology, which really enhances its low-light performance and clarity. One of the standout features is its 3x in-sensor lossless zoom, allowing you to zoom in on your shots without needing a separate telephoto lens. While it doesn’t have an ultra-wide sensor and instead uses a basic auxiliary depth lens, the main camera is fine-tuned with a “RAW domain algorithm” to boost dynamic range and improve night photography. On the front, there’s a notable upgrade with a 20MP selfie camera ($f/2.2$), up from the 16MP sensors in earlier models. This front camera supports AI beautification and portrait modes, making it perfect for social media snaps and high-def video calls. When it comes to video, both the front and rear cameras can record in 1080p at up to 60fps, delivering smooth footage. However, it doesn’t support 4K recording, which is a common compromise in this price range to focus on high megapixel counts and battery efficiency.

BATTERY AND CHARGING.

Redmi Note 15 4G is all about endurance, boasting a hefty 6,000mAh silicon-carbon battery. This cutting-edge battery tech means it packs a punch with higher energy density, giving you way more power than typical batteries without making the phone feel bulky. Xiaomi proudly claims that this battery can easily last over two days with light to moderate use, earning it the title of “battery king” in its price range. Plus, it’s built to last, rated to keep at least 80% of its health even after 1,600 full charge cycles, which means you can count on it for reliable performance for four to five years of daily use. When it comes to charging, the phone features 33W Turbo Charging, letting you hit 50% in just a little over 30 minutes. One cool highlight is its 18W wired reverse charging capability. This nifty feature turns your smartphone into a portable power bank, so you can use a USB-C cable to charge up accessories like your wireless earbuds or even lend a hand to a friend by giving their phone a quick boost.
