vivo S15e
- Fast 66W charging with quick initial boost
- Sleek and modern design (implied by vivo's brand)
- Potentially efficient 5nm Exynos 1080 chipset
- Potentially lower sustained performance compared to Snapdragon 870
- Display brightness likely lower than Poco F4
Xiaomi Poco F4
- Powerful Snapdragon 870 chipset for gaming and multitasking
- Bright 1003 nit display for excellent outdoor visibility
- Faster full charge time (38 minutes)
- Design may be less premium than the vivo S15e (subjective)
- Camera performance details are limited
Display Comparison
The Poco F4 boasts a significantly brighter display, reaching a measured 1003 nits, compared to an unspecified brightness for the S15e. This translates to superior visibility under direct sunlight. While both displays likely utilize AMOLED technology (implied by the 'Infinite' contrast ratio on the Poco F4), the Poco F4’s higher peak brightness is a tangible advantage. The lack of information on the S15e’s panel type and refresh rate leaves the Poco F4 as the clear winner in display quality.
Camera Comparison
Both phones feature 'Photo / Video' capabilities, but detailed sensor information is missing for both. However, the market positioning suggests the Poco F4 likely prioritizes overall camera performance. While the S15e may excel in specific scenarios (like portrait mode, a vivo strength), the Snapdragon 870’s superior ISP (Image Signal Processor) generally leads to better image processing and video stabilization. Without specific sensor details, it’s difficult to definitively declare a winner, but the Poco F4’s chipset gives it an edge.
Performance
The core difference lies in the chipsets. The Poco F4’s Snapdragon 870 (7nm) features a Kryo 585 CPU clocked up to 3.2 GHz, while the vivo S15e utilizes the Exynos 1080 (5nm) with a Cortex-A78 prime core at 2.8 GHz. Despite the Exynos 1080’s smaller manufacturing node, the Snapdragon 870’s architecture and higher clock speeds generally translate to better sustained performance and more efficient thermal management. The Snapdragon 870’s Adreno 660 GPU also provides a performance edge in graphics-intensive applications. This means less throttling during extended gaming sessions on the Poco F4.
Battery Life
Both devices share an endurance rating of 101 hours, suggesting comparable battery life under similar usage patterns. However, the charging speeds differ. The Poco F4 supports 67W wired charging with PD3.0 and QC3, achieving a full charge in 38 minutes. The S15e’s 66W charging reaches 50% in 18 minutes, but a full charge time isn’t specified. While the S15e charges quickly initially, the Poco F4’s complete charge time is faster, offering more convenience. The similar endurance ratings suggest the 5nm Exynos 1080 is relatively efficient, but the Snapdragon 870’s optimization also contributes to comparable battery life.
Buying Guide
Buy the vivo S15e if you prioritize a sleek design and fast 66W charging, and your usage primarily revolves around social media, casual gaming, and everyday tasks. Buy the Xiaomi Poco F4 if you demand consistent performance for gaming, video editing, or multitasking, and value a brighter, more vibrant display for media consumption. The Poco F4 is the better option for power users.
Frequently Asked Questions
❓ Does the Exynos 1080 in the vivo S15e overheat during prolonged gaming sessions?
While the 5nm process is efficient, the Exynos 1080 is known to throttle under sustained load, particularly in graphically demanding games. The Snapdragon 870 in the Poco F4 generally handles heat more effectively, maintaining higher frame rates for longer periods.
❓ Is the 2MP macro camera on either phone actually useful for taking detailed close-up photos?
Typically, 2MP macro cameras on phones in this price range offer limited detail and image quality. They are often included for marketing purposes but rarely deliver truly impressive macro photography. Expect soft images and limited dynamic range.
❓ Can the Poco F4 reliably run PUBG Mobile at 90fps?
Yes, the Snapdragon 870 in the Poco F4 is capable of running PUBG Mobile at 90fps with high graphics settings. However, sustained performance may vary depending on the device's thermal conditions and background processes.
❓ How does the charging speed of the vivo S15e compare to real-world usage?
The S15e's 66W charging reaches 50% in 18 minutes, which is very fast for a quick top-up. However, the time to reach 100% is not specified, and the Poco F4's 67W charging completes a full charge in 38 minutes, offering more convenience for users who prefer a complete charge.
