Xiaomi launches Redmi 15C with bigger battery and faster charging

Xiaomi has rolled out its new Redmi 15C, a budget smartphone that takes a big step up in battery life and charging speed while keeping its price firmly in the affordable range. The device replaces last year’s Redmi 14C and aims to grab attention with a larger screen, stronger power pack, and improved features designed for everyday use.

Bigger display and smoother refresh rate

The Redmi 15C comes with a 6.9-inch HD+ display that supports a 120Hz refresh rate, giving users smoother scrolling and better visuals while watching videos or gaming. The screen reaches up to 810 nits of brightness, making it easier to view outdoors. Xiaomi has also secured TÜV Rheinland certifications for low blue light and flicker free performance, which means longer usage with less eye strain.

The phone features a notch design with an 8MP front camera tucked inside. It is not a high-end selfie camera, but it is meant to cover casual video calls and basic photography needs.

Performance powered by Helio G81 Ultra

Under the hood, Xiaomi is sticking with the MediaTek Helio G81-Ultra processor. It is an octa-core chip that combines two Cortex-A75 cores for heavy tasks with six Cortex-A55 cores for efficiency. While not a top performer compared to flagship processors, it is tuned for smooth handling of daily apps, light gaming, and multitasking.

The device comes with RAM options of 4GB, 6GB, or 8GB, paired with either 128GB or 256GB of storage. Xiaomi also allows virtual RAM expansion of up to 8GB, giving the higher models the feel of 16GB RAM when needed. Storage is expandable up to 1TB with a microSD card, which keeps the phone flexible for users with large media libraries.

It runs on Android 15 with Xiaomi’s HyperOS 2, offering updated system optimizations and design.

Battery life takes a leap forward

The biggest highlight of the Redmi 15C is its 6000mAh battery with 33W fast charging, a major jump from the 5160mAh and 18W charging of the Redmi 14C. This means users can expect longer hours of use and faster top-ups.

To put it into perspective, a 6000mAh battery can easily last more than a day for heavy users and close to two days for average use. For many buyers in the budget range, this improvement will likely be the deciding factor.

Here’s a quick comparison of the Redmi 15C vs Redmi 14C battery setup:

This upgrade makes the Redmi 15C one of the most battery-reliable phones in its price range.

Camera setup for everyday shots

On the rear, the Redmi 15C carries a 50MP main camera with an f/1.8 lens, accompanied by a secondary sensor for depth or additional support. This setup allows users to take sharper photos in daylight and improved shots in low light conditions.

The 8MP front camera is more basic but enough for social media photos and video calls. While the phone does not focus on high-end photography, it gives a balance that fits its budget category.

Added features and design touches

The phone has a side-mounted fingerprint scanner, a 3.5mm headphone jack, FM Radio support, and IP64 dust and water resistance. At 205 grams and 7.99mm thick, it is fairly slim for its size and large battery.

It comes in four color options: Moonlight Blue, Midnight Black, Mint Green, and Twilight Orange. Xiaomi has emphasized that Moonlight Blue and Twilight Orange were created using a dual-color magnetic ink process, inspired by ocean tides and sunlight at different times of day.

Connectivity includes dual 4G VoLTE, Wi-Fi on both 2.4GHz and 5GHz bands, Bluetooth 5.4, GPS with GLONASS, and a USB Type-C port.

Pricing and availability

The Redmi 15C is priced from USD 119 (about Rs. 10,475), making it one of the most affordable large-screen smartphones with a high refresh rate and long battery life. Prices may vary depending on the region and RAM or storage configuration.

With this launch, Xiaomi is continuing its push to capture the entry-level and mid-range markets by offering premium-style features at budget prices.

The Redmi 15C does not bring a major performance leap compared to its predecessor, but its larger battery, faster charging, and smoother display could make it a hit among cost-conscious buyers who prioritize lasting power over raw speed.

As smartphones become more power-hungry with apps and streaming, devices like the Redmi 15C show that lasting battery life remains one of the strongest selling points in the budget segment.
