Redmi 15 vs Redmi 15 5G: Same Big Battery, Different Speeds

The new Redmi 15 Series brings two solid options for users who want a phone that lasts all day and performs reliably. Both models pack a 7000mAh battery, a large 6.9-inch FHD+ display, and the latest Xiaomi HyperOS 2 experience. But beneath the surface, the Redmi 15 and Redmi 15 5G have distinct personalities—one built for everyday essentials, the other tuned for speed and future connectivity. Let’s break down how they differ and which one suits you better.

Design and Display: Sleek look, identical screen quality

Both phones share a premium feel thanks to their quad-curved back with metallic accents and IP64 dust and splash resistance. The main difference lies in the finish and weight: Redmi 15 is slightly lighter at 214g and comes in Sandy Purple, while Redmi 15 5G weighs 217g and introduces Ripple Green among its colors. Each is comfortable to hold and resistant to daily wear.

The display experience is nearly identical: a 6.9-inch FHD+ panel with up to 144Hz AdaptiveSync refresh rate and 288Hz touch sampling. Brightness peaks at 850 nits (HBM), and TÜV certifications ensure low blue light and flicker-free viewing. With Wet Touch Technology 2.0, you can still swipe smoothly even with damp hands—perfect for real-world use.

Performance: Reliable 4G vs future-ready 5G

Under the hood, the Redmi 15 runs on the Snapdragon 685, a 6nm chip optimized for balanced performance and power efficiency. It handles everyday apps, streaming, and light gaming effortlessly. In contrast, the Redmi 15 5G steps up with the Snapdragon 6s Gen 3, also a 6nm processor, bringing faster graphics and, of course, 5G connectivity for those ready to jump on next-gen networks.

Both models support up to 16GB RAM (with Memory Extension) and 2TB expandable storage, ensuring plenty of space for photos, videos, and apps. The 5G version also adds Bluetooth 5.1 and optional NFC depending on region. If your area has 5G coverage, the Redmi 15 5G offers better futureproofing. Otherwise, the Redmi 15 remains a great pick for value hunters.

Camera and AI: Everyday clarity with smart tools

The two models share the same simple yet capable setup—a 50MP main camera (f/1.8) and an 8MP front camera. They capture social-media-ready shots with auto night mode and portrait beautification. For those who love creative control, the Redmi 15 5G adds AI-driven features like AI Erase for removing distractions and AI Sky for enhancing skies with one tap.

Both support Circle to Search with Google and Google Gemini integration, making it easy to find information or complete tasks through natural AI prompts. The 5G variant simply goes a bit further, offering smarter editing options built right into the gallery.

Battery and Audio: Long-lasting power and immersive sound

Battery life is the highlight of this series. Both models feature Xiaomi’s largest smartphone battery yet—a 7000mAh Surge Battery. You can expect up to two full days of use, while 33W fast charging gets you back to 100% quickly. Even better, there’s 18W reverse charging, letting you top up other devices in a pinch. The Smart Charging Engine 2.0 and Battery Health 4.0 system intelligently adapt charging speed to protect long-term battery life.

Audio is equally impressive, featuring Hi-Res Audio and Dolby Atmos for immersive sound, plus a 200% volume boost for clear playback in noisy environments. Both devices run on Xiaomi HyperOS 2, offering features like shared clipboard, call sync, and multi-device connectivity across Xiaomi’s ecosystem.

In summary, the Redmi 15 is the better value pick—affordable, long-lasting, and reliable for daily use—while the Redmi 15 5G adds 5G connectivity, a slightly faster chipset, and smarter AI tools for users who want more headroom. The series starts at USD 149 for Redmi 15 and USD 199 for Redmi 15 5G, with configurations up to 8GB+256GB.
