Massive 7000mAh Battery for Two Days of Power

One of the biggest highlights is its 7000mAh Xiaomi Surge battery, the largest ever on a Redmi device. This powerhouse can last up to two days on a single charge under light usage. Even if your battery drops to just 1 per cent, you can still make calls for nearly an hour or leave it on standby for over seven hours. With 33W fast charging and 18W reverse charging support, you can also power up other devices on the go.

Stunning 6.9-inch FHD+ Display with 144Hz Refresh Rate

For those who love watching videos, gaming, or scrolling through photos, the Redmi 15 5G’s large 6.9-inch display delivers immersive visuals. The screen supports a refresh rate of up to 144Hz, ensuring smooth scrolling and responsive gameplay. TÜV Rheinland certifications for Low Blue Light, Flicker-Free, and Circadian Friendly viewing also make it easier on your eyes during extended use.

Built for Durability with IP64 Splash and Dust Resistance

Singapore’s humid weather and occasional downpours are no problem for the Redmi 15 5G. It comes with IP64-rated splash and dust resistance, plus Wet Touch Technology 2.0 so you can still use the phone even with damp hands. While it’s not meant for full water submersion, the added protection means you can carry on without worrying about minor spills or splashes.

Reliable 5G Performance with Snapdragon® 6s Gen 3

Under the hood, the Redmi 15 5G runs on the Snapdragon® 6s Gen 3 Mobile Platform, giving you fast 5G connectivity and smooth multitasking. With up to 16GB RAM (via memory extension) and support for 2TB of expandable storage, you get plenty of speed and space for apps, media, and work files.

AI-Enhanced Photography with 50MP Dual Camera

Photography fans will enjoy the 50MP AI dual camera system, complete with creative features like AI Erase, AI Sky, and Dynamic Shots. Whether you’re snapping portraits, cityscapes, or food shots, these AI tools help you edit and enhance your photos effortlessly.

Immersive Audio with Dolby Atmos and Hi-Res Audio

If you use your phone for music or streaming, the Redmi 15 5G’s audio experience won’t disappoint. It offers Hi-Res Audio, Dolby Atmos® support, and a 200% volume boost, giving you loud, clear, and rich sound whether through the speakers or headphones.

Pricing and Availability in Singapore

The Redmi 15 5G comes in Ripple Green, Titan Grey, and Midnight Black. The 8GB+256GB variant is priced at SGD249 and is available via mi.com, Shopee, Lazada, Xiaomi Stores, and authorised retailers across Singapore.
