The Realme 16 Pro Plus 5G takes the raw brightness crown. Its 6,500-nit APL peak brightness is the headline figure, backed by a 144Hz refresh rate and a higher 2800 x 1280 resolution. In direct sunlight, it is among the brightest screens in the mid-range segment.
The Redmi Note 15 5G fights back where it matters most for daily users. Its 3,200-nit display offers 12-bit colour depth, an 8,000,000:1 contrast ratio, 3840Hz PWM dimming, and all three TUV Rheinland eye-care certifications. These are features that protect your eyes during long sessions, something the Realme page does not specify.
One correction from the previous version of this article: the Realme’s 6,500 nits figure refers to APL (Average Picture Level) peak brightness, not sustained screen brightness. Its normal mode sits at 600 nits, while HBM is 1,800 nits.
WINNER: Realme 16 Pro Plus 5G for maximum brightness and refresh rate. Redmi Note 15 5G for eye-care certifications and contrast performance.

This table makes the difference unmistakable. The Realme 16 Pro Plus 5G is a three-camera system with a dedicated 50MP periscope telephoto delivering 3.5x optical zoom and up to 120x digital zoom. The Redmi Note 15 5G has no telephoto lens at all.
The main camera gap is also significant. A 200MP Samsung HP5 sensor with 2-axis OIS and support for 4K at 60fps on the Realme sits opposite a 108MP sensor with 4K limited to 30fps on the Redmi. Both have 8MP ultra-wide lenses on the rear.
For selfies, the gap is equally wide. The 50MP front camera on the Realme crushes the 20MP sensor on the Redmi for detail, especially in low light and portrait shooting.

WINNER: Realme 16 Pro Plus 5G, clearly. It has more cameras, more zoom, better video, and a superior selfie sensor.
Battery and Charging Comparison: 7,000mAh vs 5,520mAh
Battery & Charging | Realme 16 Pro Plus 5G | Redmi Note 15 5G |
Battery Capacity | 7,000mAh (typical) | 5,520mAh (typical) |
Battery Type | Titan Battery | Silicon-Carbon (Si/C) EV-grade |
Charge Cycles | Not specified | Over 80% capacity after 1,600 cycles (~5 years) |
Wired Fast Charging | 80W Ultra Charge (SUPERVOOC) | 45W Turbo Charging |
Charger in Box | Yes, 80W charger included | No adapter included (PD 45W recommended) |
Wireless Charging | Not supported | Not supported (receive) |
Reverse Charging | Not supported | 18W wired reverse charging |
Estimated Full Charge | ~44 minutes (realme Lab) | Not officially stated |
USB Port | USB Type-C | USB Type-C |
The Realme 16 Pro Plus 5G has the larger battery and the faster charger. A 7,000mAh Titan Battery with 80W charging from the box means most users will never run out of power. Realme also includes the 80W adapter in the box. The Redmi Note 15 5G comes with a silicon-carbon battery. Xiaomi’s internal data claims over 80% capacity retention after 1,600 complete charge cycles, which translates to approximately 5 years of daily charging. That is a genuine longevity advantage. The 18W wired reverse charging is also unique in this segment. It lets you use the phone as a portable power bank for earbuds or smartwatches. Note that Xiaomi does not include the 45W charger in the box.
Storage Comparison: UFS 3.1 vs UFS 2.2
| Storage Specs | Realme 16 Pro Plus 5G | Redmi Note 15 5G |
| RAM Type | LPDDR5X | LPDDR4X |
RAM Options | 8GB / 12GB | 8GB (India); 6GB / 8GB / 12GB (Global) |
| Internal Storage | 128GB / 256GB | 128GB / 256GB (India); up to 512GB (Global) |
| Storage Type | UFS 3.1 | UFS 2.2 |
| Expandable Storage | Not supported | Yes, microSD up to 1TB (Hybrid SIM slot) |
| SIM Configuration | Dual SIM (Nano + Nano) | nano SIM 1 + Hybrid (Nano SIM or microSD) |
The Realme 16 Pro Plus 5G uses faster LPDDR5X RAM paired with UFS 3.1 storage. This combination means faster app launches, quicker file transfers, and smoother multitasking under load compared to the LPDDR4X and UFS 2.2 on the Redmi. The Redmi Note 15 5G counters with expandable storage support. The hybrid SIM tray lets you slot in a microSD card up to 1TB instead of a second SIM. The Realme offers no such flexibility. If you need more space, you are locked into the variant you buy.
WINNER: Realme 16 Pro Plus 5G on storage speed. Redmi Note 15 5G on flexibility and expandability.

The Realme 16 Pro Plus 5G ships with Android 16 and makes a clear, published commitment to 4 years of OS updates and 6 years of security patches. That is a strong promise for a mid-range phone. The Redmi Note 15 5G launches on Android 15 with HyperOS 2. Xiaomi’s update track record has improved significantly, and the global spec sheet notes up to 4 major OS upgrades. However, Xiaomi has not published a formal security patch commitment for this model. On build quality, the Realme earns an IP69 Pro rating that includes IPX9K protection against high-pressure water jets at high temperature. The Redmi’s IP65 and IP66 covers splash and dust resistance only. The Realme also uses Corning Gorilla Glass 7i. The Redmi uses a high-durability glass that passed SGS drop tests from 1.7 metres face-down onto marble. One area where the Redmi wins convincingly: audio. Dual speakers, Dolby Atmos, Hi-Res certification, and a 300% volume boost claim make it a standout media device for its price. The Realme official India page does not detail audio specs.

The Realme 16 Pro Plus 5G asks for more because it delivers more, specifically a triple camera system, faster storage, a bigger battery with a faster charger included, Wi-Fi 6, and Android 16 from day one. If you plan to keep the phone for 3 to 4 years, that investment pays off over time.

Performance Head-to-Head: Snapdragon 7 Gen 4 vs Snapdragon 6 Gen 3
The Snapdragon 7 Gen 4 in the Realme is manufactured on 4nm and clocked at up to 2.8GHz. It is paired with LPDDR5X RAM and UFS 3.1 storage, giving it a multi-layer performance advantage over the Snapdragon 6 Gen 3.
The Snapdragon 6 Gen 3 in the Redmi is also 4nm, with cores clocked up to 2.4GHz. It handles social media, streaming, light gaming, and multitasking without issue. The Adreno 710 GPU manages casual titles well. For GPU-intensive gaming, though, the Realme’s chipset pulls ahead.
For the average buyer who browses Instagram, watches Netflix, takes calls, and chats on WhatsApp all day, the Snapdragon 6 Gen 3 is genuinely sufficient. For gamers, video editors, or anyone pushing the phone hard, the Snapdragon 7 Gen 4 with its AirFlow vapour chamber cooling system is the right choice.

Conclusion
The Realme 16 Pro Plus 5G wins this comparison on raw hardware. It has the brighter display with a higher refresh rate, the more capable triple camera with genuine optical zoom, a larger and faster-charging battery, quicker storage, a more powerful chip, better water resistance, and a longer confirmed software update cycle. The Redmi Note 15 5G is not a runner-up in any shameful sense. It is one of the best smartphones available under Rs. 25,000 in India right now. The silicon-carbon battery, the certified eye-care display, the Dolby Atmos speakers, and the 18W reverse charging make it a genuinely thoughtful piece of hardware at its price. If your budget stretches, buy the Realme. You will feel every rupee of that difference in how it performs. If it does not, the Redmi Note 15 5G will not disappoint you.
