Both smartphones use the same 6 nm Dimensity 6300 processor and 6,000 mAh battery, but the realme provides faster charging, a smoother display, and higher camera resolution.
General
Both are dual-SIM 5G smartphones running Android 15, with the realme weighing about 197 g and the vivo weighing 199 g.

The realme is about 2 g lighter and slightly thinner. The vivo is taller and gives you separate slots for two SIM cards and a microSD card.
Display and design
The realme C75 5G has a 6.67-inch 120Hz LCD, while the vivo Y19s 5G has a slightly larger 6.74-inch 90Hz LCD with higher verified HBM brightness.

The realme provides the higher refresh rate, which can make scrolling and supported animations look smoother. The vivo reaches a higher verified HBM brightness figure, which can help in bright surroundings.
→ Keep in mind: Refresh rate affects how smooth movement looks on screen. It does not make the processor itself faster.
Performance and software
Both phones use the 6 nm MediaTek Dimensity 6300 with eight CPU cores and speeds reaching up to 2.4 GHz, so their basic processing hardware is closely matched.

| User interface | realme UI 6.0 | Funtouch OS 15 |
| Storage | 64GB / 128GB | 64GB / 128GB |
Neither device has a processor advantage because both use the same chipset and graphics hardware. Software optimisation, RAM configuration, storage load, and background applications can still affect day-to-day responsiveness.
→ Buy this if: Choose a 6GB RAM configuration if you regularly keep several applications open. The extra memory gives the phone more space for multitasking than a 4GB version.
Camera features
The realme C75 5G has a 32MP main rear camera and 8MP front camera, while the vivo Y19s 5G uses a 13MP + 0.08MP rear setup and 5MP front camera.
| Spec | realme C75 5G | vivo Y19s 5G |
|---|
| Rear camera setup | Single main camera | Dual camera |
| Main camera | 32MP, f/1.8 | 13MP, f/2.2 |
| Secondary rear camera | No dedicated secondary camera confirmed | 0.08MP, f/3.0 |
| Ultra-wide camera | No | No |
| Macro camera | No | No |
| Front camera | 8MP | 5MP, f/2.2 |
| Rear video recording | Up to 1080p at 30 fps | Up to 1080p at 30 fps |
| Front video recording | Up to 1080p at 30 fps | Video supported |
The realme offers higher camera resolution on both the rear and front. This can provide more image detail in suitable conditions, although lighting, processing, focus, and sensor quality also affect the final image. Neither phone has an ultra-wide or telephoto camera, so both focus mainly on basic everyday photography.
Storage and connectivity
The vivo Y19s 5G supports microSD expansion up to 2TB and has a dedicated memory-card slot, while the realme uses a hybrid SIM and memory-card arrangement.

| Storage options | 64GB / 128GB | 64GB / 128GB |
| Expandable storage | Supported through hybrid slot | Up to 2TB |

| NFC | Not confirmed | No |
| USB | USB Type-C | USB Type-C, USB 2.0 |
| FM radio | Not confirmed | Supported |
| Memory-card arrangement | Hybrid slot | Dedicated microSD slot |
→ Pro tip: The vivo is more practical if you need two active SIM cards and expandable storage at the same time. The realme's hybrid arrangement can require you to choose between the second SIM and memory expansion.
Battery and other features
Both phones have 6,000 mAh batteries, but the realme supports 45 W charging and 5 W reverse charging compared with 15 W charging on the vivo.
| Spec | realme C75 5G | vivo Y19s 5G |
|---|
| Battery capacity | 6,000 mAh | 6,000 mAh |
| Wired charging | 45 W | 15 W |
| Reverse charging | 5 W | Not confirmed |

| Speaker feature | Super Linear Speaker, 300% Ultra Volume mode | 200% Volume and Audio Booster |
| Security | Side fingerprint sensor | Side fingerprint sensor |
| Water and dust protection | IP64 | IP64 |
The equal battery capacity means charging is the clearer difference. The realme's 45 W charging provides three times the rated charging power of the vivo's 15 W system. realme also states that five minutes of charging can provide up to 4.8 hours of calling under its laboratory conditions. Actual charging and usage times can vary.
