1. Larger Battery
Redmi 15 5G features a 7,000 mAh silicon-carbon battery. Its predecessor Redmi 14 series (e.g., Redmi 14/14C/Note 14 5G), typically offered between 5,110–5,500 mAh. It means that you will experience a significantly longer battery life for your day-to-day use.
It boasts of fast 33 W wired charging, plus 18 W reverse wired charging to power your other gadgets. The battery features Smart Charging Technology 2.0, 1 % Power Lock Mode, and potentially 2.3-day usage capability on a single charge.
2. Higher Display Refresh Rate
Redmi 15 5G sports a 6.9″ FHD+ IPS display with up to 144 Hz refresh rate. In contrast, the Redmi 14 series usually had 120 Hz displays—either IPS or AMOLED, depending on the model. This means that you will enjoy smoother scrolls, animations, and gaming visuals. You will notice these when loading fast-paced content.
The device is with TÜV Rheinland certifications for Low‑Blue‑Light, Flicker‑Free, and Circadian‑Friendly display to reduce eye strain.
3. Processor & RAM Improvements
This smartphone is powered by a Snapdragon 6s Gen 3 (6 nm) chip with up to 16 GB (including virtual RAM). The processors of the previous Redmi 14C and Redmi Note 14 5G were Snapdragon 4 Gen 2 and Dimensity 7025 Ultra, respectively. With this upgrade, the company makes efforts for smoother multitasking and more efficient performance.
4. Camera & AI Enhancements
Redmi 15 5G comes with dual rear cameras (50 MP + 2 MP macro/depth), with AI features like AI Erase, AI Sky, and creative filters. In the Redmi 14 and Note 14 series, we saw higher-resolution camera sensors—for example, Redmi Note 14 5G’s triple-camera setup (50 MP + ultrawide + macro). But the Redmi 15 5G offers more AI-assisted shooting modes and creative flexibility. A plus point for photo enthusiasts!
Selfies are handled by an 8 MP front camera (f/2.2).
5. Design & Build
The device boasts a large 6.9″ display, an aerospace-style camera module, and IP64 splash resistance. The Redmi 14 series typically featured smaller screens (up to around 6.7″) and varied build materials (plastic to glass). It means that Redmi 15 5G provides a distinctly bolder look with more appealing aesthetics and durability.
6. Software Improvements & Updates
Redmi 15 5G is pre-loaded with Android 15 (HyperOS 2.x) and promises 2 OS upgrades + 4 years of security updates. Its predecessors came with shorter official support windows. This ensures that you will enjoy longer support for software issues and a smoother software experience for a long time.
7. What’s More
