Redmi 15 5G Review: Snapdragon 6s Gen 3 performance & 7000mAh battery

Xiaomi has expanded its lineup with the Redmi 15 5G, a phone built around a 7000mAh battery that simply refuses to quit — this phone is built for heavy users who hate carrying chargers around. Designed for heavy users, media & streaming, everyday use, it brings 5G connectivity, a large 7000mAh battery, a smooth 144Hz display, and the Snapdragon 6s Gen 3 chipset into one well-rounded package.

The phone sits at a competitive price in the Indian market. It doesn't try to compete with premium flagships — instead it focuses on delivering a balanced everyday experience, and in that mission it largely succeeds.

Design & Build Quality

At 217g, the Redmi 15 5G feels noticeably heavy in the hand — the price you pay for that large battery inside to hold. With an IP64 rating, it offers real protection against dust and splashes for everyday use. A side-mounted fingerprint sensor unlocks the phone quickly and reliably. Storage can be expanded via microSD, which media-heavy users will appreciate.

Design Rating: 6.9/10

Display

The phone features a 6.9-inch IPS LCD panel with a 144Hz refresh rate and 1080 x 2340 resolution. Scrolling through apps, social media and websites feels noticeably smoother than standard 60Hz displays. With 850 nits of peak brightness, it stays perfectly readable even outdoors. The ~374 PPI density keeps text sharp and crisp. It's a capable panel for everyday content, though not as vibrant as AMOLED rivals.

Display Rating: 8.1/10

Performance

Powering the Redmi 15 5G is the Qualcomm Snapdragon 6s Gen 3. Daily tasks such as browsing, video streaming, online classes, messaging and social media all run smoothly. It scores around 6,20,000 on AnTuTu, which is solid for this segment — casual games and multitasking are handled without major issues.

It runs Android 15 with HyperOS 2 on top out of the box. The interface is clean, well-optimised and easy to live with day to day.

Performance Rating: 6.4/10

Camera Performance

The Redmi 15 5G comes with a 50MP main camera. In daylight, the primary camera captures detailed photos with natural colours and good dynamic range. Video recording is limited to 1080p, which is acceptable for social media and OTT sharing. Selfies come from a 8MP front camera — good enough for video calls and social posts.

Camera Rating: 5.8/10

Battery Life

Battery life is one of the biggest strengths of the Redmi 15 5G. The 7000mAh battery easily lasts one and a half to two days with normal usage — browsing, streaming and calling without battery anxiety. The 33W fast charging tops it up quickly whenever you do need to charge. It can even reverse-charge your earbuds or smartwatch in a pinch.

Battery Rating: 9.2/10

Software Experience

The phone ships with Android 15 and HyperOS 2 on top. It comes with the usual preloaded apps, most of which can be disabled. For everyday use the software feels smooth and stable, and it stays that way over the long term.

Should You Buy the Redmi 15 5G?

If you're looking for a phone for heavy users and media & streaming, the Redmi 15 5G is a strong option. Snapdragon 6s Gen 3 performance and massive 7000mAh battery are its standout strengths. It's not perfect though — no wireless charging and no 3.5mm headphone jack may bother some buyers. For students, office users and families looking for a dependable device in this budget, it is an easy recommendation.
