Xiaomi Redmi 15 5G coming soon with gigantic 7,000 mAh battery that also doubles as power bank
After an extensive leak recently revealed numerous details about the Redmi 15 5G, Xiaomi has now officially unveiled the mid-range smartphone for the first time on a teaser website. This website confirms that the Redmi 15 5G will be officially unveiled on 19 August, 2025. The smartphone will be available in at least three colours: Sandy Purple, Frosted White and Midnight Black.
All three versions feature a strikingly textured back, ranging from a matte texture on the black model to a striking ice texture on the white variant. The real highlight is the battery, which has a remarkable capacity of 7,000 mAh. The silicon-carbon battery is said to retain 80% of its original capacity after four years of use. According to Xiaomi, the Redmi 15 5G can also be used as a power bank and charge other devices with up to 18 watts via a USB-C cable.
The battery is said to provide a runtime of 23.5 hours when playing YouTube videos or 55.6 hours when streaming music via Spotify. The mid-range smartphone features a 6.9-inch, 144 Hz display and a Qualcomm Snapdragon 6s Gen 3, a 6 nm ARM chip from 2024 that houses two ARM Cortex-A78 performance cores with boost clock speeds up to 2.3 GHz and six Cortex-A55 efficiency cores.
According to a previous leak, the Redmi 15 5G will come with 8 GB of RAM and 256 GB of flash storage. Cameras include an 8 MP selfie camera and a 50 MP main camera. To reduce costs, Xiaomi is reportedly installing an IPS panel instead of an OLED, while the casing is only IP54 certified and so not fully waterproof.
