Redmi 15 5G Leak Reveals 144Hz Display, Snapdragon 6s Gen 3, and Massive 7,000mAh Battery

Following multiple leaks surrounding the Redmi 15C 4G, new information has surfaced about its more powerful sibling — the Redmi 15 5G. The upcoming budget-friendly 5G phone from Xiaomi is shaping up to be a significant upgrade over its predecessors in both performance and battery life.

Key Highlights of the Redmi 15 5G (Leaked):

Display:

The Redmi 15 5G is rumored to feature a large 6.9-inch Full HD+ (1080p+) LCD with an impressive 144Hz refresh rate — a major leap from the 720p+ panels used in past Redmi number series models. This puts it ahead of the more common 120Hz screens in its class.

Processor & Performance:

Unlike the typical Snapdragon 4-series chips used in devices like the Redmi 13 5G and 14C 5G, the new phone will reportedly be powered by the Snapdragon 6s Gen 3, a 6nm chip paired with up to 8GB of RAM and up to 256GB of internal storage. This is a notable performance bump in the entry-level 5G segment.

Battery:

The phone's tagline — “One Charge. Two Days. Zero Worries.” — speaks to its massive 7,000mAh battery. While charging speeds are limited to 33W, the huge capacity means users may only need to recharge once every two days. Only the Redmi Turbo 4 Pro and Redmi K80 Ultra have larger batteries in Xiaomi’s lineup.

Cameras:

Camera hardware includes a 50MP main sensor, a 2MP depth/macro lens, and an 8MP front-facing camera. Nothing groundbreaking here, but it stays competitive for its class.

Extras:

The leak also confirms NFC support, a welcome addition in budget markets where it's not always guaranteed.

Expected Price:

The leaked pricing — RM 699 to RM 750 — comes from Malaysia and converts to approximately $165–$180. This places the Redmi 15 5G firmly in the affordable 5G smartphone category.

Launch Timeline

There’s no official word yet from Xiaomi on the Redmi 15 5G launch date, but with increasing leaks and the Redmi 15C 4G expected soon, both models might see staggered launches in the coming weeks.

The Redmi 15 5G is shaping up to be one of the most exciting budget 5G phones of 2025, thanks to its high-refresh-rate display, upgraded chipset, and huge battery — all at an accessible price point.
