Redmi 15C Review: Big Screen, Long Battery, Strong Value

Introduction

Redmi is known for phones that give strong value at low prices, and the Redmi 15C continues this pattern. It brings a large display, dependable performance, and a big battery, all at an affordable price. For anyone looking for a reliable phone on a tight budget, it is worth a look.
Display

The Redmi 15C comes with a 6.9 inch screen that feels big and immersive. It works well for watching videos, reading, and scrolling through apps. The screen peaks at 660 nits, so it is still visible outside in most situations.
The highlight is the 120Hz refresh rate, which makes scrolling and animations smooth. It is a rare feature in this price range. The Dot Drop notch looks a bit old, but it does not affect daily use. The phone also has an IP64 rating for dust and water resistance, which is not common for budget devices.
Design
The Redmi 15C looks and feels better than many phones in its category. The Moonlight Blue color has a soft shimmer, and it is also available in Midnight Black, Mint Green, and Twilight Orange.
Even though the body is plastic, it feels solid in the hand. At 205 grams, the phone has a weight that makes it feel steady and more premium than expected.
Camera

The phone has a 50MP main camera and an 8MP front camera. Photos look sharp in good lighting. Colors are not always perfect, but they are close enough for everyday use. Video recording goes up to 1080p at 30fps. It is not made for professional filming, but it handles basic content well.The selfie camera delivers clear shots with a bit of beauty enhancement. Portrait mode looks fine when the light is right.
Software
HyperOS 2 is the name of the phone’s user interface, which is based on Android 15. The security patches date from August 2025 and are therefore somewhat older at the time of testing. However, Xiaomi promises updates until 2031, i.e. 6 years from launch, as well as at least two new Android versions.
Performance
The phone is powered by the MediaTek Helio G81 Ultra processor. It handles everyday tasks like messaging, browsing, and social media without lag. Light games such as Mobile Legends and Roblox run smoothly with only rare drops in frame rate.
The unit tested has 4GB RAM and 128GB storage, with support for virtual RAM expansion up to 8GB. This helps multitasking and keeps the phone stable.
Battery
Battery life is one of the strongest features of the Redmi 15C. The 6,000mAh battery lasts more than a full day of heavy use. Redmi rates it for up to 22 hours of video playback, 82 hours of music, and 20 hours of reading.The phone charges with 33W fast charging, reaching 50 percent in about 31 minutes. It also supports reverse charging, so it can top up other devices.
