Xiaomi is disrupting the entry-level market with the Redmi Note 15, now retailing for approximately 182 euros via Cdiscount. This 4G handset pairs a MediaTek Helio G100-Ultra chipset with a 6,000 mAh battery and a 6.77-inch AMOLED display, targeting budget-conscious users.
Let’s be clear: the “speed” being marketed here isn’t about breaking world records in synthetic benchmarks. It’s about the price-to-performance ratio. When you drop the cost of a device below the 200-euro threshold, you usually expect a compromise in display tech or battery longevity. Xiaomi isn’t doing that. By leveraging the Helio G100-Ultra, they’ve managed to keep power consumption in check while maintaining a snappy UI experience.
It’s a strategic play. Xiaomi is providing 256GB of internal storage, ensuring that the average user isn’t fighting for space every time they update an app.
The Silicon Reality: Decoding the Helio G100-Ultra
The heart of the Redmi Note 15 is the MediaTek Helio G100-Ultra. The Helio line focuses on stability and efficiency for 4G environments. It brings the speed of global operation and controlled energy consumption.

In a market where ARM-based architectures are becoming increasingly homogenized, the G100-Ultra serves as a reliable workhorse. The integration of Google’s Gemini Live allows for fluid exchanges leading to optimizations of your ideas.
This is where the efficiency comes in. It’s a lean architecture that maximizes battery life.

- Utility: Support for reverse charging, effectively turning the phone into a power bank for your other devices.
The 6.77-inch AMOLED screen is the other standout. AMOLED technology allows for a high-level visual comfort.
