Display Comparison
Neither device boasts a particularly standout display. Both likely utilize IPS LCD panels, common in this price bracket. While specific details like peak brightness and color gamut coverage are unavailable, the focus here is on performance, not visual fidelity. Bezels are expected to be similar, typical of 2019/2020 designs. The absence of high refresh rates or advanced panel technologies like LTPO means display quality won't be a major differentiating factor.
Camera Comparison
Without detailed camera specs beyond the chipsets, a direct comparison is limited. Both phones likely feature multi-camera setups geared towards versatility. However, the image signal processor (ISP) within the Snapdragon 675 is more advanced, potentially leading to better image processing, particularly in low-light conditions. The A70s is likely to produce more detailed and vibrant photos, with improved dynamic range. The presence of a dedicated ISP in the 675 allows for faster image processing and better noise reduction.
Performance
The core difference lies in the chipsets. The Samsung Galaxy A70s features the Qualcomm Snapdragon 675 (11nm), utilizing a Kryo 460 CPU configuration with 2x 2.0 GHz Gold cores and 6x 1.7 GHz Silver cores. This contrasts with the vivo S1 Pro’s Snapdragon 665 (11nm) and its 4x 2.0 GHz Kryo 260 Gold and 4x 1.8 GHz Kryo 260 Silver setup. The 675’s architecture, with more Silver cores, suggests better sustained performance under load, particularly in multitasking scenarios. While both are 11nm chips, the 675’s CPU design offers a performance advantage, translating to snappier app launches and smoother gameplay. The A70s will handle graphically demanding games with higher frame rates and fewer stutters.
Battery Life
While battery capacity isn't specified, the real differentiator is charging speed. The Samsung Galaxy A70s supports 25W wired charging, a significant advantage over the vivo S1 Pro’s 18W charging. This means the A70s can replenish its battery much faster, minimizing downtime. Even if the A70s has a slightly smaller battery capacity, the faster charging will likely result in a more convenient user experience. A full charge on the A70s will take considerably less time than on the S1 Pro.
Buying Guide
Buy the vivo S1 Pro if you need a reliable daily driver for basic tasks like social media, messaging, and light web browsing, and prioritize a lower initial cost. Buy the Samsung Galaxy A70s if you prefer a smoother multitasking experience, enjoy mobile gaming, and value the convenience of significantly faster charging speeds. The A70s is the better choice for users who demand more from their smartphone.
Frequently Asked Questions
❓ Will the Snapdragon 675 in the Galaxy A70s handle demanding games like PUBG or Call of Duty Mobile smoothly?
Yes, the Snapdragon 675 is capable of running PUBG and Call of Duty Mobile at medium to high settings with stable frame rates. While it won't deliver a flagship-level experience, it provides a significantly smoother gaming experience compared to the Snapdragon 665 in the S1 Pro, thanks to its more powerful CPU and GPU.
❓ How much faster is the 25W charging on the Galaxy A70s compared to the 18W charging on the vivo S1 Pro in real-world usage?
The 25W charging on the A70s can realistically shave off 30-45 minutes of charging time compared to the S1 Pro. While exact times depend on battery level and usage, you can expect a full charge on the A70s to take around 1 hour 30 minutes to 2 hours, while the S1 Pro will likely take closer to 2 hours 30 minutes or more.
❓ Is the difference in performance between the Snapdragon 665 and 675 noticeable for everyday tasks like browsing and social media?
For basic tasks, the difference might not be immediately apparent. However, when multitasking or switching between apps, the Snapdragon 675 in the A70s will feel noticeably snappier and more responsive. The extra processing power prevents lag and ensures a smoother overall user experience.
